Eclipse Aptana Overview

On this page you can find information about Eclipse and Aptana. You can use these IDEs for many things, including creating Android or Web based projects.

Eclipse Logo

I use Eclipse as my Primary tool for Android development. It is an IDE, written primarily in Java, which can be extended through a series of plugins. Hence you can use it not just, or even primarily, for Android development, but for a wide range of activities such as Java, JavaScript, Python, C++, Ruby, HTML or Scheme development.


The simplest way to install Eclipse to work with Android is to do download the bundle from the following site:

Once you have the bundle, you should be able to simple unzip it and then run it.

The bundle does not come with an HTML editor. To get one, choose Help Install Software

If the bundle does not work for you, or if you want to go through the process manually, then follow these steps:

  • Be sure that Java is installed.. The JRE will not work in all cases, so you should get the JDK, which includes source code for the Java classes. To install the Oracle JDK on Ubuntu, use
  • You will need to download Eclipse Classic. The current version is called Indigo, which is version 3.7.1. Older versions are called Helios, Galileo and Ganymede. In June, 2012, which should see a new version called Juno. After installation, you should see the Java Development Tools (JDT) when you chooseHelp | About | Installation Details from the Eclipse IDE.
  • Be sure to install the ADT, Android Development Tools. The AVD and SDK manager are integrated into the Eclipse IDE.

Eclipse is Java based and does not use the Windows registry. This means you can place it wherever you want, and can simply zip it up and move it around. Java, however, is a bit more complicated, so you should first ensure that the JDK is installed and then unzip your copy of Eclipse. I unzipped my copy into my c:\users\charlie directory. I then made a link from the start menu to Eclipse.exe.

You’ll want the most recent version of Eclipse. A new release is shipped in June of each year.

##Using Eclipse {#usingEclipse}

There is extensive Eclipse documentation, including many tutorials.

When you first start Eclipse, or when you select**Help Welcome** from the menu, you see the Welcome screen:

Eclipse Welcome

Notice that there are a number of useful links in the Welcome. Browse them and become familiar with their contents. When you are ready, notice that in the upper right hand corner of the Welcome screen there is a link to the Workbench.


You can always see all the available shortcuts in any particular context by pressing Ctrl-Shift-L.


The workbench is the Eclipse name for the IDE desktop. The workbench contains a series of windows, called editors or views, and they can be arranged in various patterns, which are called perspectives. If you can edit the content in a window, then it is called a Editor, and if you can’t edit the content, then it is called a View. Typically, a perspective has one editor and multiple views.

  • Workbench: The entire IDE
  • Perspective: A particular arrangement of windows
  • Views: An individual window, or segment, of the desktop with content that can’t be edited.
  • Editors: An individual window, or segement, of the desktop with content that can be edited.


Figure 01: The Eclipse workbench with an Editor in the middle (ListViewActivity3.ja) surrounded by a series of Views (Task List, Outline, Package Explorer, Problems, Javadoc, Declaration).

Changing Perspectives

Eclipse allows you to switch perspectives, or modes, depending on your current task.

XML Files and WYSIWIG Editor

There are many different XML files involved in Android development, so they have some fancy XML editors, but that is not the same thing as an advanced. When using the visual tools to edit an XML file, you want to expose the Palette, the editor, the Outline View and the Properties view. Notice that the palette has categories, such as Text Fields. Notice that you want to set the input type for the Text Field. Notice also the Custom and Library view to find some custom views that you created yourself or got from a library.


Figure 01: The Palette, the Wysiwig editor, the outline view and the properties view.

There is an Layout ActionBar at the top of the Wysiwig editor that gives you some fancy options.

You can switch between different screen sizes, such as phone and tablet, or between portrait and landscape.

Run Configurations

Suppose you want to run a PhoneGap project out of the IDE.

  • Choose **Run Run Configurations**, or right click on your project
    and choose **Run As Run Configurations**.
  • On the left select Android Application, if it is not selected already.
  • On the right select the Android page if it is not already selected, then select your Cordova project, or click the browse button and locat it. Select the Target page.
  • Choose Always prompt to select device. This will give you a chance to pick any running Android device attached to the system, be it a VirtualBox Android VM, an AVD, or physical Android device.

After completing the above steps, sive you Run Configuration a name, hit the Apply button, and then select Run. The first time you run like this it may take 5 to 10 seconds for the dialog allowing you to pick a device to pop up. The next time, however, the dialog should appear in a second or two. The dialog will allow you to select the device in which you want to run your application.

Install the HTML Editor

Go to **Help Install New Software.Set the **Work With list to:
Indigo -

Open up or expand the option labelled Web, XML and Java EE Development,but check only the Web Page Editor. Just that one item. There is a long list of items to install, but you only need the Web editor.

Also see the section on Aptana, as it shows how to install the Aptana plugin for Eclipse


Aptana is an IDE based on the Eclipse core. It is Eclipse, but it contains several custom tools designed for web developers interested primarily HTML, CSS, JavaScript, PHP and Python developers.

At this time, Aptana is based on Eclipse 3.6 (Helios) and not Eclipse 3.7 (Indigo). You can, however, install the Andtroid Development Tools (ADT) into Aptana.

  • Select **Help New Software**, from the menu.
  • Click on Available Software Sites
  • Select Eclipse Helios Update Siteand click Ok.
  • Use the Add button to install the ADT site:

After completing the above steps you will be able to do Android and Web development in the same IDE. This is particularly nice if you are interested in PhoneGap.

Aptana Plugin for Eclipse

Alternatively, you can install the Aptana Plugin into Eclipse.

Go to **Help Install New Software.**Set the Work With list to:

If you currently have PyDev installed, you may have to remove it before you can install the Aptana Plugin.

Create a Web Project

  1. Menu: **Window Open Perspective (Other) Web**
  2. Menu: **File New Web Project Default Project**
  3. In the Project Explorer right click on your new project and choose New from Template | JavaScript | JavaScript Template
  4. Alternatively, in the App Explorer, you can right in the main panel and choose New from Template | JavaScript | JavaScript Template

It is frequently a good idea to examine the .project file created when you build a web project. Because these files begin with a period, they will be treated as “hidden” files on most operating systems. As a result, you may need to tweak your file explorer to allow you to view hidden files.

These .project files are short text files, and they are not difficult to understand, at least in part. Here for instance, is a simple .project file for a web project:

<?xml version="1.0" encoding="UTF-8"?>

Notice the name of the project:


If you import this project into Eclipse, then this name will be displayed in the project manager.

I usually create web projects in Eclipse. However, there is nothing to prevent you from copying the files from one directory into a second directory. This allows you to quickly create a new project based on the work of an existing project. This system works fine, but in such cases you have to be careful to give the new project a name that differs from the name of the original project.

You cannot import two projects with the same name into the same Eclipse workspace. This means that you have to take care in certain cases:

  • If you copy a .project file from one project to another. In this case you can easily end up with two .project files with the same name. The solution is simple, open one of the .project files in an editor, and change the name.
  • If you are student in a class turning in an assignment. In such cases, you will usually want to include your name in the project, to distinguish your work from others in your class:


In general, .project files for web projects seem mysterious and confusing at first. However, they are not really very complicated and you can easily learn to work with them.

Aptana: Import Existing Web Site

If you have a big website that you want to start editing in Aptana, then you probably don’t want to use the Aptana mechanism for import it because it requires that you move files from one location to another. In other words, you probably have the files in the place where you want them, so why move them just to start using Aptana? There is, however, a simple way to create an Aptana project for your site

If possible create a workspace just one step closer to the root of of the file system than the project you want to import. This is not necessary, but may be useful, especially if you have several big web sites that you want to import in the same way described here. If you can’t or don’t want to take this step, then just open a workspace somewhere on your system.

Switch to Project Explorer. At the top, it says Local File System. Use this view to navigate to your project. Right click on the root directory for your site. Choose Promote to Project.

Remove a Plugin

Choose Help | Install Softare. Click on the What’s Already Installed? link. Select the item you want to uninstall, and press the uninstall button. (There is some chance this button is not available in earlier versions of Eclipse. In that case, I believe the correct thing to do is disable the feature that you want to remove from the IDE.)

Import a Project

If you have a project on disk that is not visible inside of Eclipse, then you need to import it. When you import the project, you add it to the IDE, so that you can see it in the Project Explorer or similar tools.

There are (slightly) different techniques for importing projects into Eclipse depending on the type of project you wish to add to the IDE. If the project is a Cordova project, then choose:

  • Import Android Existing Code into Workspace

If it is a Web Project, then choose:

  • Import General Existing Projects into Workspace

There are other ways to import other types of projects into Eclipse, but the two examples shown above should give you enough of a sense of how things work so that you can figure out how to import a Java project, Python project, or some other type of project.

Eclipse uses a file called .project to track the configuration for the projects that it maintains. This file must exist before you can import a project using the type of techniques shown above. If you just have a folder with some files in it, and there is no .project file in the folder, then choose:

  • Import General Existing Folder into Project

This will create a default .project file and allow you to begin working with the project inside the IDE. In some cases, it may be better to first create a project in Eclipse, then copy your files into the folders that Eclipse created. But for simple Web Projects, then the import existing folder option should work just fine.

HTML Snippets in Aptana or Aptana Plugin

You can create snippets in Eclipse. These snippets can be easily triggered and insert into your code at any random point. I like to set the trigger and name for each of them to begin with my initials so I can easily find my templates. Below is a screen shot showing them visible when I trigger code expansion (crtl-space) in Eclipse.

In Eclipse, from the menu: Commands | HTML | Edit this Bundle. **This should create a project called **HTML and open it in Eclipse.

In the Project Explorer, open the project called HTML. Open the templates folder and edit the file called templates.rb. Insert your snippets into the file and restart the IDE.

Here are example snippets, where trigger is what you type to trigger the snippets in the IDE after you type ctrl + space.The expansion is the code that you want to have pasted into the IDE when you choose the snippet:

snippet "csc jQuery CDN" do |snip|
  snip.trigger = "cscJQueryCDN"
  snip.expansion = "<script src=''></script>"

snippet "csc jQueryMin CDN" do |snip|
  snip.trigger = "cscJQueryMinCDN"
  snip.expansion = "<script src=''></script>"

snippet "csc Paragraph ID" do |snip|
  snip.trigger = "cscParagraphID"
  snip.expansion = "<p id=''> </p>"

Here is an example of multiline snippet. Notice that I escape the jQuery dollar sign symbol with a backslash: \$. This is necessary because the $ symbol has special meaning inside snippets:

snippet "csc jQuery Document Ready" do |snip|
  snip.trigger = "cscJqDocReady"
  snip.expansion = '\$(document).ready(function() {
    "use strict";

Below is a screen shot showing what it looks like when you edit the snippets in templates.rb. Note the you should have snippets that begin with your initials, not with mine. For instance, if your name is John Paul Jones, then your snippets could have names like jpjJQueryCDN.


Besides thetemplates.dbfile, notice also the snippets folder in the HTML project and the snippets.rb. (By the way, rb files are Ruby scripts.)

The ruble specification appears to be something that is being developed by the Aptana team. It first appeared in Studio 3, and the source is being maintained on Github. More information on the project can be found here:

Eclipse and JSHint

You can integrate JSHint into Eclipse. To install JS Hint integration into Eclipse, choose Help | Install | Add from the Eclipse menu and enter a name (ie JSHint) and this URL:

Here is what it looks like:


After you have installed JSHint, you can turn it on project by project. Bring up the context menu for your project by right clicking on the project. Select Properties and expand the JSHint node. You can turn JSHint on for all the JavaScript files in the project, or for some subset of the JavaScript files in the project. After installation is completed, I find that JSHint often does not show its hints until I save the file that I am editing. The hints usually show up as yellow flags on the left hand side of the editor.


For instance, create a web project called JSHint-LastName where LastName is your last name. A sceen shot showing the project name in the JSHint dialog is visiable above. To find the dialog, right click on your project to bring up the context menu, and then choosing Properties. **Expand the JSHint options, and set up a rule to turn on JSHint for the file **index.js in the root folder for your project. An example screen shot is shown above.

If you are using jQuery, in the options dialog, perhaps you need to add the following: “jquery: true”.

Suppose you have the following line in your code:

$("#time2").html("Also jQuery name: " +;

If you are using JSHint integration in Eclipse, you will get two warnings on this page, one for the $ from jQuery, and one for device from Cordova. Of course, both $ and device are defined elsewhere, and should be part of our code. They are not an error or a mistake. So how do we get rid of them? One way to eliminate these warnings is to place the following at the top of JavaScript file:

/*global $:false, device:false */

It turns out that jQuery is so commonly used that there is a general way to tell JSHint to ignore everything having to do with jQuery:

/*jshint jquery:true */

Notice that here we use jshint rather than global, and we set jquery to true, rather than setting $ to false. Regardless of the specifics, the comment ends up calming JSHints fears without affecting our code at run time. In particular, because the message to JSHint takes the form of a comment, it is ignored by the JavaScript run time engine.

Another approach is to put the following in the top option window in the JSHint dialog you get to from the properties context menu for the project. More specifically: right click on the project in the Project Explorer, then select Properties | JSHint | Options and set the following value, exactly as shown, in the Predefined globals window:


Now add the following to the JSHint Options window (that’s the lower of the two windows):

jquery: true

This still leaves problems with things console.log, alert, and window object. To eliminate these warnings, once again bring up the JSHint Options dialog and place all of the following in the JSHint Options window:

browser:true, devel:true, jquery:true

Here is what it looks like on my system:


Another option you should consider is strict:true.

Run JSHint as an External Tool

From inside of Eclipse you can run JSHint against the file you are currently editing. To make this work, you first need todownload the source to JSHint from the JSHint github site. The download is a zip file. You should unzip the contents of the file and place it in a well known location on your hard drive, such as the C:\Dev folder.

  • Choose **Run External Tools External Tool Configuration**
  • Select Program and click the New button
  • Set Name = JSHint
  • Set Location=C:\Windows\System32\cscript.exe
  • Set two arguments
  • Argument1 = C:\Development\jshint-r12\env\wsh.js
  • Arbument2 = ${resource_loc}

JSHint run as an External tool

Figure 01: Press the Run button to run JSHint against the current JavaScript file open in your Eclipse Editor. The results appear in the console window at the bottom of your screen.

Here is a bit more explanation of the various fields you should fill out in the External Tools Configuration dialog.

  • The Location is set to cscript.exe, which is a JavaScript compiler that ships with Windows.
  • The first of the two arguments is the path to my downloaded copy of JSHint, and in particular, to the wsh.js file, which is designed to work with the Windows JavaScript engine.
  • The second of the two arguments is a macro that resolves to the name of the file currently open in the editor. More details on the available macros are found in the Eclipse help on the external tools page.

To run this command from the IDE, choose the smaller of the two green Run buttons found on the toolbar, or just press the run button from inside the External Tools Configurations. You can see this button at the bottom right of the screen shot shown above. If by some chance you can’t find the Console window, you can access it from Window | Show View | Console(Alt + Shift + Q, C).

If you wanted to run a similar command from the command prompt, you might type something like this:

cscript C:\Development\jshint-r12\env\wsh.js c:\Temp\CordovaAndroid\assets\www\js\index.js

The command shown above has three parts:

  1. We call cscript, which is stored in c:\windows\system32 directory, which means that it should always be on our path.
  2. The firstargument points to the location where we unzipped our JSHint download. More specifically, it points to that location, and then to a particular file called wsh.js stored in the env folder. This file implements JSHint for the Windows Script engine (cscript.exe).
  3. The third argument points to the file that we want to check. The outpoint will show up on the command line.

If you are running JSHint from the command line, or as an external tool, you can specify options by placing a comment like this at the top of your JavaScript source file:

/*jshint jquery:true, browser:true, devel:true, strict:true */

You can also ask JSHInt to ignore a global variable. For instance, the following ignores a global identifier called device:

/*global device: false */

Wrapping Operators

  • **JavaScript Code Style Formatter**
Then **Edit Expressions Binary Expressions**

Then turn off Wrap before operator.
