NullPointerException with jgit on Git Plugin 2.0 beta















There is a simpler way to show the same (or a similar) stack trace:


	Define a new job using Git as the SCM
	Assign an ssh repository URL like ssh://mwaite@somehost/git/myrepo.git



The stack trace reports a null pointer exception visible in the web browser:

Status Code: 500

Exception: java.lang.NullPointerException

NullPointerException with jgit on Git Plugin 2.0 beta















Issue Type:


Bug



Assignee:


Nicolas De Loof



Components:


git



Created:


26/Jul/13 7:14 PM



Description:


Steps I used to see the issue:


	installed Git Client plugin 1.1.1 and restarted Jenkins
	downloaded and installed Git Plugin 2.0 beta and restarted Jenkins
	executed several successful builds without changing configurations
	confirmed those builds were correctly responding to build hooks
	use configuration page to delete git as executable, add jgit
	submitted another change to git repository, watched hooks activate



No build from Jenkins, and a null pointer exception is in the log file.

When I select "Build Now" on another job, it includes the message in its output:

selected Git installation does not exists. Using Default

That surprises me, since the "JGit" implementation is the only available implementation on my Jenkins server currently, and it is built into Jenkins.

If I then define a Git command line provider in the global configurations and adjust the problem job to use that command line provider, the job works again.
