JD-GUI

JD-GUI is a standalone graphical utility that displays Java source codes of ".class" files. You can browse the reconstructed source code with the JD-GUI for instant access to methods and fields.

Forked from

• Java Decompiler projects home page: http://java-decompiler.github.io
• JD-GUI source code: https://github.com/java-decompiler/jd-gui
• QuiltFlower source code: https://github.com/QuiltMC/quiltflower

Changes in this fork 2022.3.28

1. QuiltFlower 1.7.0 embedded and used by default instead of JD Core.
2. Decompile jar with Quiltflower on Save All Sources (Ctrl+Alt+S) yet not individual classes which are still decompiled by JD Core.
3. Set at org.jd.gui.service.preferencespanel.ClassFileDecompilerPreferences.decompileWithQuiltflower using org.jd.gui.service.preferencespanel.GenericPreferencesPanelProvider and org.jd.gui.service.preferencespanel.Preference implementations like org.jd.gui.service.preferencespanel.QuiltflowerFileSaverPreferencesProvider for org.jd.gui.service.preferencespanel.QuiltflowerFileSaverPreferences
4. Code Reformatted with .idea/ProjectCodeStyle.xml
5. Added .idea files to repository except .idea/workspace.xml
6. Naming convention for version YYYY.MM.DD instead of 1.6.6 core 1.1.3
7. Preferences (Ctrl+Shift+P) of SourceSaver set to false so original line numbers and metadata are not generated by default.
8. Save All Sources (Ctrl+Alt+P) of a jar file named pkg.jar pkg-sources.jar will suggest the file name in order to comply with maven conventions.
9. Planned changed:
   1. Integration with other decompiler libraries using preferences at app/build.gradle 2. CFR main site hosted at benf.org/other/cfr
   2. Upgrade of ANTLR services/src/main/antlr/Java.g4 using /grammars-v4/tree/master/java/java
