How to access git commit message INSIDE sh STEP in a jenkins pipeline?

I need to access commit message of current fetch from git repository, while completing some sh steps of different stages of a pipe in jenkins; but I didn't find any proper solution for it. It would be also nice if I could set the commit message as an environment variable, so that I could access it later on.

Please note that this is not a repetitive question, because none of similar questions on stackoverflow addresses exactly what I need. I need to have commit message in all of sh steps of my pipeline.

You can get the commit message for the fetched commit ID and set it as an environment variables as follows:

stage('get_commit_msg') {
    steps {
        script {
            env.GIT_COMMIT_MSG = sh (script: 'git log -1 --pretty=%B ${GIT_COMMIT}', returnStdout: true).trim()
        }
    }
}

You can then use ${GIT_COMMIT_MSG} in Shell scripts in any downstream stage of your pipeline.
