---------------------------------
Summary: jgit tag failure is not failing the build
Key: SCM-854
URL: https://issues.apache.org/jira/browse/SCM-854
Project: Maven SCM
Issue Type: Bug
Components: maven-scm-provider-jgit
Affects Versions: 1.9.5
Reporter: Paul Vonnahme
If the 'scm:tag' command fails, I would also expect the build to fail. This
usually happens, however, we've come across a scenario where the tag fails but
the build still shows as "BUILD SUCCESS". This happens when the tag is
rejected by a pre-receive hook. Here is an example of the output:

I haven't cloned any code, but using the online viewer, it looks like what
needs to happen is in the JGitUtility, the push needs to check the status,
rather than just logging it:
https://github.com/apache/maven-scm/blob/4c13db8164691aca57ab6279c550e339e7639ae4/maven-scm-providers/maven-scm-providers-git/maven-scm-provider-jgit/src/main/java/org/apache/maven/scm/provider/git/jgit/command/JGitUtils.java#L195
A status of 'OK' is good, but if one or more of the others is found, I believe
an exception should be thrown?
http://download.eclipse.org/jgit/docs/jgit-2.3.1.201302201838-r/apidocs/org/eclipse/jgit/transport/RemoteRefUpdate.Status.html
If we want to limit the change, and not throw a new exception from JGitUtils,
further checking of the push result could happen here:
https://github.com/apache/maven-scm/blob/4c13db8164691aca57ab6279c550e339e7639ae4/maven-scm-providers/maven-scm-providers-git/maven-scm-provider-jgit/src/main/java/org/apache/maven/scm/provider/git/jgit/command/tag/JGitTagCommand.java#L93
