Enhanced Class Decompiler integrates JD, FernFlower, Vineflower, CFR, Procyon seamlessly with Eclipse and allows Java developers to debug class files without source code directly. It also integrates with the eclipse class editor, m2e plugin, supports Javadoc, reference search, library source attaching, byte code view and the syntax of JDK8 lambda expression.

Enhanced Class Decompiler is a plug-in for the Eclipse platform. It integrates JD, FernFlower, Vineflower, CFR, Procyon seamlessly with Eclipse, allows you to display all the Java sources during your debugging process, even if you do not have them all, and you can debug these class files without source code directly.

This is an ad-free fork of the Eclipse Decompiler Plugin. So we enhanced it by removing all code which might compromise your privacy or security (to the best of our knowledge).

Drag and Drop installation:

If you have currently the "Eclipse" Class Decompiler installed, it is recommended to uninstall that plug-in first and remove the corresponding update site from your Eclipse installation.

1. Launch Eclipse,
2. Click on "Help > Install New Software...",
3. Drag and Drop enhanced-class-decompiler-x.y.z.zip
4. Check the components to install,
5. Click on "Next" and "Finish" buttons.
6. A warning dialog windows appear because plug-in is not signed. Click on "Install anyway" button.

1. Click on "Window > Preferences > General > Editors > File Associations"
2. "*.class" : "Class Decompiler Viewer" is selected by default.
3. "*.class without source" : "Class Decompiler Viewer" is selected by default.

1. Click on "Window > Preferences > Java > Decompiler"

Source attach:

You may configure a private Nexus repository with credentials (user/password) to download and attach sources automatically :

You may select from a list of available public repositories :

You may use this option "Wait for sources to be downloaded before trying to decompile" to avoid decompiling code for which you have sources.

Use this icon to switch decompiler while a class file is still open. Once a file is closed and re-opened, the source is cached, it is no more possible to switch decompiler.

1. Click on "Help > About Eclipse > Installation Details > Installation Software",
2. Select "Enhanced Class Decompiler",
3. Click on "Uninstall...".

Requiremnent: JDK 11 or newer (make sure JAVA_HOME environment variable points to an appropriate JDK)

If you want to test the latest features of this plugin, you have to build it from source. For this, proceed as following:

1. git clone https://github.com/ecd-plugin/ecd
2. git clone --depth 1 https://github.com/ecd-plugin/update next to this project
3. Run mvn clean package

If you want to use Eclipse and help developing, continue like this:

4. Install Eclipse for RCP and RAP Developers
5. Import all projects into Eclipse by selecting File > Import > General > Existing Projects into Workspace > Next and enter the parent of the cloned directory as "root directory".
6. Open the org.sf.feeling.decompiler.updatesite project in the Package Explorer
7. Open the file site.xml within the project
8. Press "Build All"
9. Copy the jar files generated in the build/features and build/plugins folder of the project into the correspondent folders of your normal Eclipse installation.
