Jenkins does not recognize command sh?

Question

I\'ve been having a lot of trouble trying to get a Jenkinsfile to work. I\'ve been trying to run this test script:

#!/usr/bin/env groovy
node {
    stage(\'         


        

Answer 1

In my case, I did this.

1. Remove Path variable from Jenkins Environment variables.

2. Added 'withEnv(['PATH+EXTRA=/opt/flutter/bin'])' in my steps.
