Title: Message Title

David Ishee created an issue   Jenkins / JENKINS-33907 Git plugin clone fails on linux slave with Java 1.7 Issue Type: Bug Assignee: Mark Waite Components: git-plugin Created: 2016/Mar/30 3:42 PM Environment: Jenkins 1.609.2 git-plugin v2.4.4 Java 1.7 Priority: Critical Reporter: David Ishee I have Jenkins running on a Linux machine as master, and a slave on the same machine. Git clone's fail on the slave, but work on master. Running Java 1.7 for master and slave. I've restarted the slave, and upgraded to the latest git-plugin. Exception on slave is: I seems like the root cause is: Caused by: java.lang.UnsupportedClassVersionError: org/eclipse/jgit/util/Java7FSFactory : Unsupported major.minor version 51.0 Why does this happen on a slave, and not on a master node? Does your plugin support Java 1.7?
