github https://github.com/nviennot/jd-core-java JD-Core-java is a thin-wrapper for the Java Decompiler. This is hack around the IntelliJ IDE plugin. It fakes the interfaces of the IDE, and provides access to JD-Core. Since the Author of JD-Core is not willing to provide a library, and we all want to batch decompilation, this is pretty much our only option. I hope this will motivate the author to release a proper library.
