[FIXED] Run git command in Jenkins failing

Issue

GIT_COMMIT is returning null, so I tried to run the following command:

env.GIT_COMMIT = sh(script: "git rev-parse HEAD", returnStdout: true).trim()

I am now getting the following error:

fatal: not a git repository (or any of the parent directories): .git

I do have my git repo in my Jenkins workspace. Where am I supposed to run the shell script? I have multiple stage looking like:

stage('Checkout GIT')
stage('Do something else')
stage('Do an other thing')

I've been trying to run the shell command in one of these 2 last stages

Solution

You can also specify the location of your repo by wrapping your git commands into dir:

stage('Checkout repo') {
  steps {
    dir ("{env.WORKSPACE}/<path_to_repo>") {
      script {
        <your code here>
       ...
