Re: Git Publisher fails with NPE when trying to push a tag Please provide more details of the job definition which is being used to create the tag and push it. For example, answers to the following questions are needed: What are the steps to reproduce the problem? What job type (Freestyle, Pipeline, Multi-branch Pipeline, Matrix, ...)? What is the git source server and what protocol is being used (ssh or https)? What is the credential type used for the git publisher (private key or username/password)?

Re: Git Publisher fails with NPE when trying to push a tag

Please provide more details of the job definition which is being used to create the tag and push it.  For example, answers to the following questions are needed:

# What are the steps to reproduce the problem? # What job type (Freestyle, Pipeline, Multi-branch Pipeline, Matrix, ...)? # What is the git source server and what protocol is being used (ssh or https)? # What is the credential type used for the git publisher (private key or username/password)? Based on the stack trace and [this line|https://github.com/jenkinsci/git-plugin/blob/a7264a2c84a935b6444032c50820d34521d55f43/src/main/java/hudson/plugins/git/GitPublisher.java#L192] in the plugin source code, I'd guess that the project name is set to null.  That is quite unexpected since a project name is seen by users.  I don't know how a user would react to a null or empty project name,.

Re: Git Publisher fails with NPE when trying to push a tag

I just ran into the same issue. The project name is not empty in my case. To answer the specific questions: In my job, I have the following steps: Clone/Fetch from SCM (git) Execute script (custom for node.js build) Archive artifacts Push tag to github - this step is configured to only happen in a release build Freestyle job Github Enterprise using HTTPS protocol Credentials are username/password The push is happening in a release build (using Github Release plugin). If I move the push to a normal post-build step (with the same parameters) the exception is not thrown.
