Enhanced Class Decompiler integrates CFR, FernFlower, JD, Procyon, Vineflower 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, byte code view and the syntax of JDK8 lambda expression.
It is based on the popular (delisted) "Eclipse Class Decompiler" Plugin, but members of the open-source community enhanced it by removing all code which might compromise your privacy or security (i.e. everything discussed in https://0x10f8.wordpress.com/2017/08/07/reverse-engineering-an-eclipse-… and everything else which seemed suspicious) to bring back the great core plugin functionality to all Eclipse users.

please help i wanted to edit this plugin for lag with a bit of code my friend showed me but im too dumb to figure out how to edit things. I can only ctrl+f and replace things to change stuff but i can't add any lines. my other friend's minecraft server is dying slowly due to not having enough ram and this plugin can help reduce the lag so playing on the server is bareable.

Hi, I had the same issue. I went to Preferences->General->Editors->File Associations, selected both "*.class" and "*.class without source" associating them to Class Decompiler Viewer as default. In Preferences->Java->Decompiler check that the Default Class Decompiler suits your environment. Hope this helps.

Can't permanently set association Decompiler Viewer for *.class
Submitted by Pavel Kouzmitcheu on Tue, 11/12/2019 - 12:20
I'm fighting with the issue for long time, and can't find the solution.
I just did the clean Eclipse 2019-09 installation and added ECD to it. Even though the flag "Set Class Decompiler Viewer as the Default 'Java Class File' content type editor" is set looks it doesn't have any effect.
Yes, I can go to "File Associations" and set Decompiler Viewer for both "*.class" and "*.class without the source" file types, and it works but only temporary till the next restart.
After I restart Eclipse it sets the OOTB Class File Viewer for both *.class types.
Any idea how to fix it? I tried all possible combinations, created new workspaces and etc. - nothing helped. the same issue happened with the older Eclipse versions as well
It is annoying to manually associate types each time I restarted Eclipse.

It works fine with Eclipse 2019 09. Decompiler version: 3.1.1.201811062102 .Eclipse: Version: 2019-09 R (4.13.0) Build id: 20190917-1200. I'm using FernFlower decompiler, but I'm sure others will work as well.
The only problem I can't solve is to permanently set "Class Decompiler Viewer" for *.class associations. After I set it the decompiler works fine, but after the restart Eclipse restores "Class File Viewer" as default association for *.class. I tried multiple different steps to update the class default association, but after each start Eclipse restores it to the "Class File Viewer", and I don't know how to prevent it from doing it. Any advice will be appreciated (note in decompiler settings I have the Startup flag checked to set the Decompiler as default viewer - it doesn't help)

I have the same combination of versions here regarding Eclipse (for committers) and the ECD plugin. While I can see the ECD settings in the overall Preferences dialog (Window / Preferences), I cannot see the menu items for displaying decompiled class files or attaching sources fetched online. The plugin has turned useless for me with 2019-09. Any advice?

Submitted by Ilya Basin on Sat, 06/29/2019 - 05:14
In general, this plugin is satisfying, and the feature to automatically show Maven sources instead of decompiling is great. However there's one annoying thing about it: the plugin actually saves the attached sources path in the native Eclipse project configuration. This is bad for version control, please don't do that
Instead, supply the source code through the same channel the plugin supplies the decompilation result. Again, the feature is great and I don't want to disable it.

Decompiler not working in eclipse oxygen

Does not integrate with the debugger
Submitted by Vasil Panushev on Thu, 11/23/2017 - 04:58
Works fine when opening a .class file from the project tree.
But when I'm debugging an application and reach a file for which I don't have a source, the decompiler editor is not opened. Instead I see a "Source not found." editor with "Edit Source Lookup Path.." button.
.class and .class without source are associated with the Class Decompiler Viewer as suggested in the documentation.
Any setting that I missed.

This is a misleading error message from eclipse and is usually triggered by a errornous network configuration - in fact, in can be any network problem.
Did you check if you need a proxy configured in Eclipse? If the problem persist, navigate manually to https://ecd-plugin.github.io/update/ download the jar files and place them in the features and plugins folde rof your eclipse installation.
