Title: Message Title

Adrian Wyssmann created an issue   Jenkins / JENKINS-61983 The ci-pipeline fails immediately with git.exe rev-parse "null^{commit}"" returned status code 128 Issue Type: Bug Assignee: Unassigned Components: bitbucket-branch-source-plugin Created: 2020-04-21 07:04 Environment: Jenkins ver. 2.222.1 Priority: Minor Reporter: Adrian Wyssmann I used to do the following in the Jenkins file   library identifier: "pipeline-helper@$env.BRANCH_NAME", retriever: modernSCM( [$class: 'GitSCMSource', remote: 'https://scm.sc.intra/scm/jenkins/pipeline-helper.git', credentialsId: 'bitbucket.service.user' ]) defaultCipipelineMaven { nodes = 'devops' /* label of jenkins nodes*/ email = 'y...@comapny.org' } The usage of `$env.BRANCH_NAME` made it easy to test changes of a feature branch of the `pipeline-helper` without that I had to manually change the branch identifier. This worked well until now where this suddenly results in an error ERROR: Could not resolve null hudson.plugins.git.GitException: Command "D:\jenkins\tools\git\bin\git.exe rev-parse "null^{commit}"" returned status code 128: stdout: null^{commit} stderr: fatal: ambiguous argument 'null^{commit}': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git <command> [<revision>...] -- [<file>...]' I recently updated from the previous LTS version 2.204 but not sure if that's when it started failing...   Add Comment   This message was sent by Atlassian Jira (v7.13.12#713012-sha1:6e07c38) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
