Jenkins通过git合并分支实现自动打包_jenkins自动合并代码

实现功能：git提交代码，然后Jenkins自动打包两次，提交前的分支一次，合并后的分支一次

如：dev提交到master，使得Jenkins打两个包，即dev分支在提交合并请求时打一次，

在合并请求完成后master分支打一次

git的webhooks设置

1. Url填入jenkins的job配置

2. 勾选合并请求触发构建，勾选后在合并请求过程中会根据jenkins的详细控制进行触发

在git合并分支，触发webhooks时，会向Jenkins传递相应参数，如下示例：

以下为打开合并请求时携带的参数：
gitlabBranch : dev
gitlabSourceBranch : dev
gitlabActionType : MERGE
gitlabUserName : Administrator
gitlabUserEmail : admin@example.com
gitlabSourceRepoHomepage : http://10.9.8.185/gitlab-instance-02db178f/demo
gitlabSourceRepoName : demo
gitlabSourceNamespace : GitLab Instance
gitlabSourceRepoURL : git@10.9.8.185:gitlab-instance-02db178f/demo.git
gitlabSourceRepoSshUrl : git@10.9.8.185:gitlab-instance-02db178f/demo.git
gitlabSourceRepoHttpUrl : http://10.9.8.185/gitlab-instance-02db178f/demo.git
gitlabMergeRequestTitle : Update dev3
gitlabMergeRequestDescription : 
gitlabMergeRequestId : 6
gitlabMergeRequestIid : 6
gitlabMergeRequestState : opened
gitlabMergedByUser : root
gitlabMergeRequestAssignee : 
gitlabMergeRequestLastCommit : 9549b3448ccf41995dba6ec723715ad361676702
gitlabMergeRequestTargetProjectId : 2
gitlabTargetBranch : main
gitlabTargetRepoName : demo
gitlabTargetNamespace : GitLab Instance
gitlabTargetRepoSshUrl : git@10.9.8.185:gitlab-instance-02db178f/demo.git
gitlabTargetRepoHttpUrl : http://10.9.8.185/gitlab-instance-02db178f/demo.git
gitlabBefore : 
gitlabAfter : 
gitlabTriggerPhrase :
 
注：当完成合并请求时，gitlabMergeRequestState 的状态会改变，如下：
gitlabMergeRequestState : merged

Jenkins项目的触发设置

Jenkins配置

1. http://10.9.8.185/project/demo 为job的url，需要填入gitlab webhooks 的配置

2. 根据gitlab的触发请求选择触发构建的条件，控制权在gitlab webhooks，

如gitlab 没有push请求则jenkins不会因为gitlab的push触发构建

但合并请求的详细控制在jenkins，分别对应：打开请求，新的commit提交，完成合并，关闭合并等

Jenkins的maven文件示例

在完成git和Jenkins项目的配置后，需要根据需求书写Jenkins pipeline的maven打包文件

注：以下示例中的jacoco、junit、sonar需要额外插件

pipeline {
    agent any 
    stages {
        stage('parameters'){
            steps{
                sh '''
