Github user kjmrknsn commented on the issue: https://github.com/apache/zeppelin/pull/2658 @kokes I confirmed that CI test against JGit 4.9.0 always fails and one against JGit 4.5.4 passed. ## JGit 4.9.0 * comimt: https://github.com/kjmrknsn/zeppelin/commit/2afba274c83d4e9f4527fcde41e09c7707c89a4c * CI test result: https://travis-ci.org/kjmrknsn/zeppelin/builds/310104872 ## JGit: 4.5.4 * commit: https://github.com/kjmrknsn/zeppelin/commit/27b08c9d0a938dbe1e70ed27c4e6f1ba21c4dafd * CI test result: https://travis-ci.org/kjmrknsn/zeppelin/builds/310107611 So, I think JGit version should be 4.5.4, which is the latest version for Java 7: https://projects.eclipse.org/projects/technology.jgit
