git - Jenkins 管道 : How to build new artifacts only if has a new commit

Question

stage('Checkout repo'){
    git branch: 'mybranch', 
    credentialsId: '6b83e39e-1c8c-44c2-9165-b1f5a857f6cb', 
    url: 'git@gitlab.com:myproject.git'}

stage('run tests'){
    sh 'mvn test'
}

stage('build artefact'){
    sh 'mvn clean package'
}

如何仅在有新提交时运行测试并制作新 Artifact ？没有触发器

Answer 1

您可以使用 Git Plugin 中的环境变量并创造一个条件:

if (env.GIT_COMMIT != env.GIT_PREVIOUS_SUCCESSFUL_COMMIT) {
  stage('run tests'){
    sh 'mvn test'
  }
  stage('build artefact'){
    sh 'mvn clean package'
  }
}

• GIT_COMMIT - 当前提交的 SHA
• GIT_PREVIOUS_SUCCESSFUL_COMMIT - SHA来自同一分支的先前成功构建的提交。
