How to get the git latest commit message and prevent the jenkins build if the commit message contains [ci skip]?

Question

I tried to get the git commit message in jenkinsfile and prevent the build based on commit message.

env.GIT_COMMIT doesn't return the commit details in jenkinsfile.

How to get the git latest commit message and prevent the jenkins build if the commit message contains [ci skip] in it?

I had the same issue. I'm using pipelines. I solved this issue by implementing a shared library.

The code of the library is this:

// vars/ciSkip.groovy  def call(Map args) {     if (args.action == 'check') {         return check()     }     if (args.action == 'postProcess') {         return postProcess()     }     error 'ciSkip has been called without valid arguments' }  def check() {     env.CI_SKIP = "false"     result = sh (script: "git log -1 | grep '.*\\[ci skip\\].*'", returnStatus: true)     if (result == 0) {         env.CI_SKIP = "true"         error "'[ci skip]' found in git commit message. Aborting."     } }  def postProcess() {     if (env.CI_SKIP == "true") {         currentBuild.result = 'NOT_BUILT'     } } 

Then, in my Jenkinsfile:

pipeline {   stages {     stage('prepare') { steps { ciSkip action: 'check' } }     // other stages here ...   }   post { always { ciSkip action: 'postProcess' } } } 

As you can see, the build is marked as NOT_BUILT. You can change it to ABORTED if you prefer, but it cannot be set to SUCCESS because a build result can only get worse
