jad(decompiler) i n eclipse

JadClipse is a plug-in that seamlessly integrates Jad (the fast Java decompiler) with Eclipse.

Normally, when opening a class file the Class File Viewer will show a brief API outline of the class. If you install this plug-in, however, the Class File Viewer will be replaced with the JadClipse Class File Viewer that shows the decompiled source of the class. This task is accomplished by decompiling the corresponding class file in the background using Jad. Normal Java syntax highlighting as well as the Outline View are supported.

17 April 2006 - JadClipse 3.2.2 released

Changes:

• Possibility to reformat the decompiled code using the Eclipse code formatter. Check out the new option Preferences... > Java > JadClipse > Use Eclipse code formatter. This new option may interfere with formatting instructions of Jad and is therefore experimental and disabled by default.
• Preferences... > Java > JadClipse > Debug: Decompiled code is only aligned if the the output of line numbers is turned on.
• Improved integration of Outline View. Folding and other features are now supported as well as double clicks for toggling breakpoints. Breakpoints work best when the option Preferences... > Java > JadClipse > Use Eclipse code formatter is disabled and the two options under Preferences... > Java > JadClipse > Debug are enabled.

Installation

• Put the JadClipse JAR file into the plugins folder of your Eclipse installation.
• Restart Eclipse (eclipse -clean).
• Get Jad.
• Put the Jad executable into a directory that is in the execution path of your operating system. Alternatively, you can configure the path to the Jad executable under Window > Preferences... > Java > JadClipse > Path to Decompiler. (Set the full path, e.g. C:\Program Files\Jad\jad.exe)
• Go to Window > Preferences... > General > Editors > File Associations and make sure that the JadClipse Class File Viewer has the default file association for *.class files.

Troubleshooting

The JadClipse plug-in is not activated when I start Eclipse.

You'll need to launch Eclipse with the -clean flag to allow the environment to detect the plug-in. Subsequent launching of Eclipse won't require the -clean flag.

eclipse -clean

The Eclipse Class File Viewer instead of the JadClipse Class File Viewer is opened.

Go to Window > Preferences... > General > Editors > File Associations and make sure that the JadClipse Class File Viewer has the default file association for *.class files.

The JadClipse Class File Viewer does not show the decompiled source.

If the editor contains the following text segment JadClipse was not able to execute the Jad binary. Make sure that the path to the binary (Path to Decompiler) is set correcly in the preferences.
