Open source libraries are very popular in Java world. Nowadays Java/J2EE/Android developers often work with Java-based projects which using a lot of open source Java libraries.
One issue with using open source Java libraries is how to find documentation/source code for these open source libraries fast and easily? It is tedious and time consuming to search for the source code, download and attach source code packages to the libraries. If your project has 40 libraries, how long will it take to find source code for all libraries?
The solution is to use this Eclipse plugin to do the task for you with only one mouse click. This Eclipse plugin will help to find source code for open source Java libraries automatically from Internet. Just right click on a Java library, choose the menu item "Attach Java Source" and wait. The source code for the library will be found and attached to the Java library in several seconds.
- Use Update site URL: http://svn.codespot.com/a/eclipselabs.org/free-plugins/trunk/site/
- Or download offline: download plugin from http://svn.codespot.com/a/eclipselabs.org/free-plugins/trunk/site/plugin... and save it to eclipse/dropins/ folder
Note for Android developers:
- When programming Android projects using Google ADT plugin, the jar files inside libs folder will be added as libraries automatically but Eclipse will not allow change source code path for these libraries. This plugin can attach source code for Android libraries and will help Android developers in coding / debugging.
Right click on a Java library of a Java-based project and choose the menu item "Attach Java Source" and wait for the source code to be downloaded/attached to the library automatically (you will see a background job is running on Eclipse status bar).
- Find source code for Java libraries using all popular Java repositories on Internet (Like Maven Central repository, Nexus-based repositories, Eclipse P2 repositories, ...)
- (NEW) Now Eclipse plugin developers can use this plugin to find source code for Eclipse plugins using Eclipse P2 repository. Please provide feedback if you are plugin developer.
- The plugin also uses a special cloud-based search service designed for the plugin. This search service contains information about all Apache Java projects. This means source code for any Apache Java-based library will be found.
- If source code for a Java library cannot be found, the user can help the community by providing the URL to the source code archive file (in Zip or Jar file format) or SCM URL (see below note) and the source code will be found next time! You are helping youself and others when providing information about source code for a library!
Tested with Eclipse 3.5 to 3.8 (but should also work with 4.x).
- JDK 5+
- Eclipse 3.5+
- An Internet connection (to search and download source code)
SCM URL format (used when you provide source code location from SCM systems):
The SCM URL will follow the format supported at http://maven.apache.org/scm/scm-url-format.html with option fragment to indicate version as below. Various SCM types are supported (Git SVN CVS Mercurial ...).
You might also like the plugins:
- Java Examples Search to find example code from Eclipse.
- Java Dependency Viewer to view your class dependencies and package dependencies visually.

I tried attaching the sources of SWT and the JDT but neither of them works.

I just installed this plugin in a Kepler Eclipse and asked it to attach the source for one of the core Eclipse plugins so that I could see how it worked. Plugin sources no longer seem to be included in Eclipse releases, and I had been very frustrated trying to find them. But this Attacher found them automatically, downloaded and attached them in a few minutes.
Worked like a charm. I can't speak for other Open Source jars, but for Eclipse plugin sources, it was exactly what I needed.

I tested with Eclipse 3.8 and your specified jar file at http://repo1.maven.org/maven2/com/google/code/gson/gson/2.2.4/ and it worked correctly for me.

Thank you for this lovely tool! However, the option to 'Attach Java source' is grayed out for libraries that are in a different folder like say src/webroot/web-inf/lib. Also this option is grayed out when I try accessing it from the Navigator view, it's available in the Project Explorer view though. It would be nice if it can be activated for arbitrary libraries and in Navigator.

You must have the jar in the Build path of project first, the plugin cannot attach source code for any jar files not in project's Build Path.

You say in the description :
Now I installed your pluggin (kepler eclipse release) but I find no way of attaching the source - can I provide a file/folder URL to the my library project in the workspace ?
Please help, if this really solved the (very annoying issue) with ADT I will be sure to advertise !

In Package Explorer view, expand "Referenced Libraries" of your Java project, right click on your jar file(s), choose the menu "Attach java Source". That's it.

Is there a way to correct the database when it attaches the wrong source jar? The plugin keeps trying to attach the jcommander source to the testng library.

Sorry but there is no way to remove wrong links, could you give me the name+version or the md5 of the jar file? I will search and remove it from database

i tried axis.jar and commons-beanutils.jar with eclipe 3.6
I select the "Attach source file" option, and after doing this, I click on a class file but eclipse says "source not found"

There are some libraries which are not easy to find the source code automatically because it is not in our database yet. For these cases, you can help by providing the URL of the source code bundle (in zip or jar format) and the database will save the URL. Next time, you or other users will find the source code automatically.
