@vfiee , each of the commands have its own shell. Thus, cd path would not be retained. I suggest adding a script that performs the install. This way you only have a single post pull exec command.

However, it could be a neat feature to add a script to execute:

{
    git {
        repo github-vite-demo {
            base_dir /tmp/ssh
            url https://github.com/vfiee/github-vite-demo.git
            branch main
            auth key /root/.ssh/id_rsa
            post pull script {
                name changeDir
                content {
                  cd /tmp/ssh/github-vite-demo
                  npm run install
                  npm run build
                }
            }
        }
    }
}

                npm run build

              }

          }

      }

  }

}

OK, thank you for your timely reply. I'm looking forward to the way shell is executed.

[vfiee]

Running the shell is possible, thank you very much! I'll close the issues.

post pull exec {
                name changeDir
                command /bin/sh
                args "/scripts/installAndbuild"
            }
