Jenkins Release artifact job running on Windows fails in Git push command

I am building a Jenkins Job on Windows to automate the release process. Hence I am using the Maven release plugin.

When I do a Perform Maven Release on the job, it asks me for the SCM login, SCM Comment Prefix and SCM tag. But the job fails while doing a git push to commit the changes with the following logs.

I believe this error has to do with running a ssh agent for the Jenkins job. I followed the solution given in the stackoverflow question Maven - Error Releasing Code to GitHub (Hangs After Push) and the git push works fine in a terminal.

The SCM parameters settings in pom.xml are as follows

<scm>
        <connection>scm:git:git@github.com:elizabetht/StudentEnrollmentWithREST.git</connection>
        <developerConnection>scm:git:git@github.com:elizabetht/StudentEnrollmentWithREST.git</developerConnection>

    </scm>

Output of mvn scm:validate is as follows

Could anyone help with pointers on how to get this running as a Jenkins job on Windows?

To add to the answer https://stackoverflow.com/a/21568234/2748399, always check the jenkins logs for more detailed error. Thanks Elizabeth (https://stackoverflow.com/users/2997040/elizabetht) for mentioning me in the post!


I followed the workaround, found by @Saravana Kumar Periyasamy given under the topic 'Possible issues between Jenkins and Github' from the link https://wiki.jenkins-ci.org/display/JENKINS/GitHub+Plugin

Forced the Jenkins to run as the user that has the SSH key configured, uploaded the SSH Key generated without passphrase and viola, I made my successful Maven Release using Jenkins (After 116 attempts in figuring out the correct configuration with this Jenkins job!!)

Here is the output from the console

[INFO] Checking in modified POMs...

[INFO] Working directory: C:\Program Files (x86)\Jenkins\workspace\Upload REST Release Artifacts
[INFO] Release preparation complete.

And then the job proceeded to upload my artifacts to my release repository.

The elements in pom.xml are as follows (this worked)

<scm>
        <connection>scm:git:git@github.com:user/repo-name.git</connection>
        <developerConnection>scm:git:git@github.com:user/repo-name.git</developerConnection>
        <url>git@github.com:user/repo-name.git</url>            
      <tag>HEAD</tag>
  </scm>

In my Jenkins job configuration, I specified the Repository URL in the following format

git@github.com:user/repo-name.git

instead of using https://github.com/user/reponame.git

The entire steps I followed to get the maven release working through Jenkins is available under http://elizabetht.github.io/blog/2014/02/05/jenkins-release-upload/
