当没有更改推送到 GitHub 时，阻止 jenkins 管道阶段失败

Question

帮助我阻止一个阶段失败，阻止进一步的阶段失败，从而阻止整个构建。问题归结为没有任何更改可以提交到 GitHub 的阶段。代码如下：

pipeline {
agent { label 'master' }

  environment {
    // 'This value is exported to all commands in this stage'
    blah
    blah..
    blah...
  } 
stages {
    stage('Check Environment') {
        steps {
            sh "echo 'Build_Id:  ' $BUILD_ID"
            sh "echo 'Job_Name:  '  $JOB_NAME"
            sh "echo 'Build_Name:  '  $BUILD_NAME"
            sh "echo 'Current Branch Name:  '  $BRANCH"
        }
    }

    stage('Checkout Source Code') {
        steps {
            git branch: 'develop', url: 'git@github.com:something-some/otherthing.git'
       }
    }

    stage('Snapshot - Version Upgrade') {
           environment {
                VERSION = readMavenPom().getVersion()
            }
        steps {
            script {
                sh '''
                #!/bin/bash -xe
                echo $VERSION
                mvn build-helper:parse-version versions:set versions:commit '-DnewVersion=${parsedVersion.majorVersion}.${parsedVersion.minorVersion}.${parsedVersion.incrementalVersion}'
                git status
                git add .
                MVN_VERSION=$(mvn -q -Dexec.executable="echo" -Dexec.args='${project.version}' --non-recursive org.codehaus.mojo:exec-maven-plugin:1.3.1:exec)
                git commit -m "Jenkins version upgrade - ${MVN_VERSION}"
                git push --set-upstream origin $BRANCH
                    '''
            }
        }
    }

    stage('Test Release - Deploy Packages To Artifactory') {
        steps {
            script {
                sh '''
                    blah
                    more blah..
                    '''
            }
        }
    }

当stage没有变化时（'Snapshot - Version Upgrade'）-stage失败了，我该如何阻止它失败，请帮忙。

这是失败的日志中的 sn-p：

如果有变化，您只能执行commit 和push：

if [ ! -z "$(git status --porcelain)" ]; then
    git commit -m "Jenkins version upgrade - ${MVN_VERSION}"
    git push --set-upstream origin $BRANCH
fi

如果您不熟悉--porcelain，请参阅documentation on git-status。
