Jenkins permission denied

Jenkins

I've just installer a new (and first) Jenkins in my openshift account.

I selected the manven automativally (from apache, version 3.2.2) install in (jenkins->coinfiguration) ..

Then, I created a new job from my own git repository.

However, when I ran this job, I got the following exception:

Any idea?

The java error java.net.BindException: Permission denied is a generic error (not specific to Jenkins), that indicates the app is trying to listen in on a port that's not permitted. On Unix in particular, that would be a port below 1024 if the user is not root. Typically, your Jenkins instance is configure to be listening on port 80 directly, that could be a problem if the java process is not running as root. Try setting it to listen on port 8080 instead. Then use this port in your browser, or (more typically) front end your Jenkins with an Apache instance running as root on port 80, and proxying for Jenkins on port 8080.
