如何获取拉请求的Jenkinsfile中已更改文件的列表？

问题描述

在请求请求构建期间是否可以在Jenkinsfile中获取已更改文件的列表？我目前正在这样做...

def changeLogSets = currentBuild.rawBuild.changeSets
    for (int i = 0; i < changeLogSets.size(); i++) {
        def entries = changeLogSets[i].items
        for (int j = 0; j < entries.length; j++) {
            def entry = entries[j]
            def files = new ArrayList(entry.affectedFiles)
            for (int k = 0; k < files.size(); k++) {
                def file = files[k]
                print file.path 
            }
        }
    }

但是如果我是第一次构建新分支，则此方法不会返回任何更改，因为没有以前的构建可与之进行比较。有没有人找到解决方案？

谢谢

解决方法

据我所知，没有内置功能可以做到这一点。

幸运的是，您可以通过编程找到答案：

    def local_branch = sh (
        script: "git rev-parse --abbrev-ref HEAD",label: "Getting current branch name",returnStdout: true
    ).trim()
    println "Local branch is ${local_branch}"

    def base_branch = 'master' 
    // This is very naive.
    // In reality,you need a better way to find out what your base branch is.
    // One way is to have a file with a name of a base branch.
    // Another one is to invoke API,e.g. GitHub API,to find out base branch.
    // Use whatever works for you.
    println "Base branch is ${base_branch}"

    sh script: "git fetch origin --no-tags ${base_branch}",label: "Getting base branch"

    def git_diff = sh (
        script: "git diff --name-only origin/${base_branch}..${local_branch}",returnStdout: true
    ).trim()

现在，您在git_diff变量中有了已更改文件的列表。

使用Jenkins变更集通常无效，并且保留用于其他目的。

这也可以通过 pipeline-github 插件实现：

def changedFiles = pullRequest.files.collect {
    it.getFilename()
}
