permission denied when executing the jenkins sh pipeline step

Question

I have some trouble with this situation: everytime I create a new pipeline job ( entitled "pipeline"), the sh step won't work even with simple command like ls or pwd and it returns this log:

sh: 1: /var/jenkins_home/workspace/pipeline@tmp/durable-34c21b81/script.sh: Permission denied

Any suggestions?

Answer 1

I guess you use

stage(name){
   sh ./runSomething
}

Jenkins always uses to user jenkins for running scripts. There are some possibilities:

1. Jenkins is running with a different user, maybe you start it with some other user.
2. Something went running when installing jenkins, check that you have a jenkins user

Answer 2

I was getting a similar permissions denied error after following the Jenkins pipeline tutorial for a node project.

./jenkins/test.sh: Permission denied

The original pipeline Test stage looked like the following and returned that error.

stage('Test') {
    steps {
        sh './jenkins/test.sh'
    }
}

I found the following post: https://stackoverflow.com/a/61956744/9109504 and modified the Test stage to the following

stage('Test') {
    steps {
        sh "chmod +x -R ${env.WORKSPACE}"
        sh './jenkins/test.sh'
    }
}

That change fixed the permissions denied error.
