Java decompiler plugin not working
I have the JD-eclipse-plugin installed. I want to decompile the classes within a jar-file. So I select the jar-file within Project-Explorer and click Decompiler in the Menu. However both decompilers (JAD and JD-core) are greyed out.
I also tried the steps shown in this blog on AVAJAVA Web Tutorials. I guess the blog is a bit outdated, however I can see within Windows-->Preferences-->Java-->Decompiler that Jad is correctly set up. But there is no JD-eclipse found within Preferences-->General-->Editors-->File Associations as you can see in the following image.
. Now I right click the jar-file within Project-Explorer, but there is no such "Attach Source File".
Did I miss anything to set up the plugin?
EDIT: I´m using the following setup: Eclipse: Mars.1 Release (4.5.1); JadClipse 4.0.0; JDK 1.8
EDIT2: Forgot to mention that I use Tomcat and want to dive into the libraries from /WebContent/WEB-INF/lib. This is not working, I cannot further collapse the jar-files.
Obviously I mixed the actual JD-eclipse-plugin an a plugin called JadClipse for Eclipse which is a slightly different plugin from eclipse marketplace. Thus when I followed the installation instructions of JD-eclipse, I could set the options for the screenshot posted within the question. So I set JD-eclipse as default for both *.class-files with and those without source-code.
Second mistake I did was a pretty silly and obvious one, namely that I wanted to browse the jar-files from within WEB-INF-folder of my Tomcat instead of from within Java Resources. Thus I could not dive into the jar-files at all hindering me to get to the class-level and thus to decompile those classes contained within the jar.
I hope this helps anyone outside also having trouble with the plugin for eclipse.
