Build step 'Play!' marked build as failure

I've configured settings as the plugin's page instructed and set play path to /home/ec2-user/play-1.2.5.3/play which exists but jenkins build always failed at:

play path is /home/ec2-user/play-1.2.5.3/play
Executing /home/ec2-user/play-1.2.5.3/play clean "/var/lib/jenkins/jobs/proj-web/workspace" 
[workspace] $ /home/ec2-user/play-1.2.5.3/play clean /var/lib/jenkins/jobs/proj-web/workspace
Build step 'Play!' marked build as failure
Finished: FAILURE

the jenkins log showed:

java.io.IOException: Cannot run program "/home/ec2-user/play-1.2.5.3/play" (in directory "/var/lib/jenkins/jobs/proj-web/workspace"): error=13, Permission denied

Tried chmod 777 to both the play dir and the workspace dir without luck, was I missing something?

Problem resolved. I placed play dir into another user's home, which jenkins has no permission to visit.
