java - Trying to run decompiler in Eclipse Luna -

i trying debug jar file don't have source for, in eclipse luna

i have tried various decompilers, , can't things run.

the recent seems jdeclipse-realign @ http://mchr3k.github.io/jdeclipse-realign/

it installs without trouble. have set set default file association "class without source" "class file editor" this

i added jar file debugged external jar project. , when expand , right click on .class file shown on web page jdeclipse-realign, decompiled source default.

and getting blue , white icons jdeclipse-realign when select class file.

but no decompiled source :( , clicking blue icon attach decompiled source nothing.

i feel must missing 1 basic thing, can't figure out. no errors, no source.

or should using different decompiler? known work in luna?

faced same problem on luna , did following:-

1. open eclipse luna
2. go -> eclipse marketplace
3. in find box, type "jad". [stands java decompiler]
4. you single result titles "jadclipse eclipse ".
5. click on install , restart eclipse when prompted. issue fixed.
