Debug Playframework in Eclipse

Question

I just moved from Netbeans to Eclipse. In Netbeans, I can debug Playframework applications out of the box. However, in Eclipse, it seems hard to configure this in order to debug

Answer 1

As of Play 2.1.2, I was getting the 'address in use' error when running play debug run.

The fix was to edit play.bat in play-2.1.2 directory and change these two lines:

:setDebug
set JPDA_PORT=9999

to

:setDebug
set JPDA_PORT=8551

Then in Eclipse, select Debug Configurations, find "Remote Java Application", do New. Then set port to 8551. Now you can start play using

play debug run

And then in Eclipse start debugging using the debug configuration you created about.
