Jenkins获取git文件变更列表、提交ID、提交人、提交信息

GitLab 事件触发 Jenkins 构建只是一个启动信号，获取变更文件列表需要知晓上一次构建时某个仓库的版本号，这里 Jenkins 的插件 git-plugin 已经帮我们实现了这部分工作。所以只需要通过 git-plugin 检出代码即可。

检出代码

    checkout([$class:'GitSCM',
        branches: [[name: "*/$branchName"]],
        doGenerateSubmoduleConfigurations: false,
        extensions: [[$class:'RelativeTargetDirectory',
            relativeTargetDir: "$relativeTarget"]],
        submoduleCfg: [],
        userRemoteConfigs: [[credentialsId: "$credentialsId", url: "$gitUrl"]]])

请自行替换

$branchName

为分支名，

$relativeTarget

为检出相对路径，

$credentialsId 

为用户凭据，

$gitUrl

即 GIT仓库地址。

获取信息脚本demo

pipeline {
    agent any
    stages {
        stage('拉取代码'){
            steps {
                checkout([$class:'GitSCM',
                    branches: [[name: "*/$branchName"]],
                    doGenerateSubmoduleConfigurations: false,
                    extensions: [[$class:'RelativeTargetDirectory',
                        relativeTargetDir: "$relativeTarget"]],
                    submoduleCfg: [],
                    userRemoteConfigs: [[credentialsId: "$credentialsId", url: "$gitUrl"]]])}}
        
        stage('构建代码'){
            steps {
                script{
                    List<String> changes = getChangedFilesList()
                    println ("文件变更列表: " + changes)
 
                    String gitCommitId = getGitcommitID()
                    println("CommitID: " + gitCommitID)
 
                    String gitCommitAuthorName = getAuthorName()
                    println("提交人: " + gitCommitAuthorName)
 
                    String gitCommitMessage = getCommitMessage()
                    println("提交信息: " + gitCommitMessage)}}}}}
