Cannot upgrade git plugin beyond 3.3.0

[Sam K]

Hi

  This is at least the second time I'm facing this issue.  When i updated core Jenkins from 2.47 to 2.58 and now from 2.58 to 2.71.  I cannot upgrade git plugin beyond 3.3.0.  

   BTW, what is the difference between git client plugin and git plugin?  Do I need both?  Is one for the traditional Jenkins jobs and the other for declarative pipelines or something?  

   Our repos are hosted in bitbucket cloud.  After upgrading the git plugin, during a typical checkout, it hangs for a moment and continues but the pipeline fails because nothing got checked out.  The workspace is empty.  Once I downgrade the plugin back to 3.3.0, its fine.  

The block of code checking out from git:

       

def create_env(IP_ADDRESSES){
 git url: 'g...@bitbucket.org:company/scripts.git', branch: 'master'
 sh (script: "./create_test_env.sh ${IP_ADDRESSES} ", returnStdout: false)
 }

Error or failed checkout behaviour.  The pipeline continues without complaint that checkout did not happen and fails in the very end when it cannot find some scripts.

So you are using the SCM side of the plugin not the SCMSource side of the plugin.

There should be zero changes on the SCM side between 3.3.0 and 3.4.0 as the only changes were on SCMSource... seems very strange

I had a similar problem with our Windows nodes. One of them always threw an exception and the other one did not complete GIT commands. In the end I reinstalled the slave software (especially slave.jar). After that all worked as expected.

[Sreeram Krishna]

Thomas, did you delete the slave.jar and let Jenkins download a new one to the slave and reconnect?  I tried disconnecting and reconnecting the slave, but did not try what you did.

Yes, he downloaded the latest version of slave.jar from his Jenkins server.

Refer to https://issues.jenkins-ci.org/browse/JENKINS-45352 for the details of his investigation.

Thanks. 

Not sure if that will help me though as my slaves are all linux slaves.  Besides, I do believe disconnecting and reconnecting did install a newer slave.jar for me as is evident by its timestamp.
