Jenkins运行脚本文件

Question

I have a Jenkins Pipeline that runs a script file.

I have tested the script outside of Jenkins and it runs perfectly but when I try to run it as part of the pipeline I get the following error:

/maint/git-branches.sh: line 2: syntax error: unexpected "("

The script is:

#!/bin/bash
branches=()
eval "$(git for-each-ref --shell --format='branches+=(%(refname))' refs/heads/)"
for branch in "${branches[@]}"; do
   echo "${branch##*/}"
done

And my pipeline stage is:

stage ('Fetching Branches') {
          steps {
            script {
              def branchcollection = sh (script: "sh maint/git-branches.sh", returnStdout: true).trim()
              BRANCH = input message: 'Choose branch to pull from', ok: 'Ok', parameters: [choice(name: 'BRANCH', choices: "${branchCollection}", description: '')]
            }
          }
        }

All the ')' brackets match up so there's no loose ones anywhere.

Answer 1

The pipeline code is running git-branches.sh explicitly with sh . On some systems sh is not Bash, and does not support Bash-specific features. In this case it looks like sh does not support arrays. Try modifying the pipeline code to ... "bash maint/git-branches.sh"... .
