Jenkins GitLab 集成代码下载部分

代码下载部分

找一个pipeline 类型的项目进入流水线语法， 找到片段生成器中的 checkout 。 我们使用checkout方法来进行代码下载（svn也是支持的哦） 

checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: '655050bf-da7e-4ca6-85f3-3fb03b2155ad', url: 'http://139.198.166.235:81/devops/devops-hello-service.git']]])

 这样在那个分支提交就会下载哪个分支的代码了

每个项目的代码库地址是不一样的，可以从gitlab里面信息获取到,，这些都是自动触发获得的，要是手动触发就拿不到了。

拿到project下面的git_http_url

  "project": {"id": 3,"name": "devops-hello-service","description": "","web_url": "http://76c03cb0fea1/devops/devops-hello-service","avatar_url": null,"git_ssh_url": "git@76c03cb0fea1:devops/devops-hello-service.git","git_http_url": "http://76c03cb0fea1/devops/devops-hello-service.git","namespace": "devops","visibility_level": 0,"path_with_namespace": "devops/devops-hello-service","default_branch": "master","ci_config_path": null,"homepage": "http://76c03cb0fea1/devops/devops-hello-service","url": "git@76c03cb0fea1:devops/devops-hello-service.git","ssh_url": "git@76c03cb0fea1:devops/devops-hello-service.git","http_url": "http://76c03cb0fea1/devops/devops-hello-service.git"},

}
