Here's my setup:
CentOS 6
Tomcat6 installed via yum
git 1.7.1 installed via yum
Jenkins v1.444 running under tomcat6
git-parameter 0.1
I have a project checked out from github over ssh using the git plugin. The project has 1 tag and many revisions, but when I create a git parameter that lists either tags or revisions, the parameter comes up blank.

Any ideas?
