避免代码merge后无法构建发布（GItlabCI + Jenkins）

1.准备工作

目标： 开发人员提交代码后触发GitlabCI ，如果有merge请求则触发Jenkins对源分支在开发环境构建测试。

2.GItlab配置

开启仅允许pipeline成功后才能merge选项

项目注册runner

项目添加.gitlab-ci.yaml文件

tags: gitlab-runner 的标签

scripts: 调用runner运行的脚本 这里讲脚本做了软连接为gitlabci   后面两个参数分别是 gitlab项目的id  jenkins项目名称

3.Python脚本

这个脚本需要软连接到/usr/bin/gitlabci,主要采用gitlab库和jenkins完成。

                #print("触发成功 构建失败！--> 请检查项目参数")
                #return False
