Fetch a specific string from Git commit message in Jenkins-CodePudding

I am fetching git commit message from my Jenkin freestyle project by cloning the git repo, by using the below command.

git log -1 --pretty=%B ${GIT_COMMIT}

I am able to get Git commit message using this, but I want to fetch only the specific message from that commit line . For example: [pqr9022827] ABAP Unit -> is the commit message I am obtaining, I need to know how to obtain only those string within the square brackets i.e., pqr9022827 and store it in some environment variable

CodePudding user response：

You can get all the logs according to your commit message git log --all --grep='<your commit message>'

stage ("Git Log") {
  steps{
    script {

      GIT_LOG = sh (
       script: "git log -1 --pretty=%B ${GIT_COMMIT}",
       returnStdout: true
      ).trim()

      EXTRACTED_GIT_LOG = sh (
       script: "echo ${GIT_LOG} | cut -d '[' -f2 | cut -d ']' -f1",
       returnStdout: true
      ).trim()

      echo "${EXTRACTED_GIT_LOG}"
    }
  }
