java - Jenkins - 如何将覆盖率报告发布到 github

Question

我正在尝试使用github-pr-coverage-status-plugin ，文档说我需要在我的主分支上运行以下命令:

step([$class: 'MasterCoverageAction'])

但是当我将其添加到管道中时，出现以下错误:

java.lang.UnsupportedOperationException: Can't find GIT_URL or CHANGE_URL in envs: {BRANCH_NAME=master, BUILD_DISPLAY_NAME=#41, BUILD_ID=41, BUILD_NUMBER=41, BUILD_TAG=jenkins-testci-master-41, BUILD_URL=https://jnkns-ci.myserver.com/job/testci/job/master/41/, CLASSPATH=, HUDSON_HOME=/var/jenkins_home, HUDSON_SERVER_COOKIE=01f6aedeea333d1f, HUDSON_URL=https://jnkns-ci.myserver.com/, JENKINS_HOME=/var/jenkins_home, JENKINS_SERVER_COOKIE=01f6aedeea333d1f, JENKINS_URL=https://jnkns-ci.myserver.com/, JOB_BASE_NAME=master, JOB_DISPLAY_URL=https://jnkns-ci.myserver.com/job/testci/job/master/display/redirect, JOB_NAME=testci/master, JOB_URL=https://jnkns-ci.myserver.com/job/testci/job/master/, RUN_CHANGES_DISPLAY_URL=https://jnkns-ci.myserver.com/job/testci/job/master/41/display/redirect?page=changes, RUN_DISPLAY_URL=https://jnkns-ci.myserver.com/job/testci/job/master/41/display/redirect}

Finished: FAILURE

我尝试了多种方法来注入(inject)这些变量。在我最近的尝试中，我什至查看了 source code for this class ，所以我将管道更改为:

pipeline {

  agent any

  options {
    skipDefaultCheckout()
  }
  environment {
    // calling credentials() actually sets 3 environment variables
    // GIT_HUB with  <username>:<password>
    // GIT_HUB_USER with <username>
    // GIT_HUB_PSW with <password>

    GIT_HUB = credentials('tmhjenkins')
    DOCKER_REPO  = 'mobilityhouse'
    DOCKER_HUB   = credentials('tmhitadmin')
    GIT_URL_PROPERTY = "https://$GIT_HUB@github.com/mobilityhouse/testci.git"
  }

  stages{
    ...
    ...
stage('Coverage & Tests') {
      steps {
        sh 'pip3 install -e .'
        sh 'make coverage-xml'
        script {
          currentBuild.result = 'SUCCESS'
          sh(script: 'export GIT_URL_PROPERTY="https://$GIT_HUB@github.com/mobilityhouse/testci.git"')
          env.GIT_URL_PROPERTY = "https://$GIT_HUB@github.com/mobilityhouse/testci.git"
          step([$class: 'MasterCoverageAction'])
        }
      }
    }

...

}

唉，这也失败了。那么我应该如何在管道内正确使用这个插件呢？任何帮助将不胜感激。

绕了一段时间后，我决定更深入地了解这个 Jenkins 插件的作用(issue report in github 并没有产生太多结果......)

事实证明，主覆盖率报告已正确存储，例如正确设置了环境变量:

  step([$class: 'MasterCoverageAction',
              scmVars:
                [GIT_URL:
                 "https://github.com/xxx/testci.git",]
            ])

这会在 JENKINS_HOME 的 XML 日志文件中添加一个条目，但是插件会提示:

Can't find master coverage repository: https://github.com/xxx/testci/pull/8 in stored: {https://github.com/myorga/testci/pull/5=0.6923, https://github.com/xxx/testci/pull/6=0.6923, https://****@github.com/myorga/testci.git=0.5385, https://github.com/xxx/testci/pull/7=0.5385}

这亮起了红灯，所以我深入研究代码并发现了问题。即 PR 被插件检测为: https://github.com/xxx/testci/pull/6 但是主覆盖操作应该只保存 https://github .com/xxx/testci 因此在配置文件(解析为 HashMap )中找不到该 key 。读完代码后，修复代码非常容易。

在githubprcoveragestatus/CompareCoverageAction.java中我替换了:

final float masterCoverage = masterCoverageRepository.get(gitUrl);

使用以下行

float masterCoverage;
if (gitUrl.contains("pull/")) {
    final String myCorrectURL = "https://github.com/" + GitUtils.getUserRepo(gitUrl);
    // Using  masterCoverageRepository.get(myCorrectURL); is failing because URL is
    // https://github.com/USER/REPO/pull/PR_ID
    buildLog.println(BUILD_LOG_PREFIX + "myCorrectURL:" + myCorrectURL);
    masterCoverage = masterCoverageRepository.get(myCorrectURL);
} else {
    masterCoverage = masterCoverageRepository.get(gitUrl);
}

这解决了我的问题，本着开源的良好精神，我向fix how a URL for Pull Request is detected提出了 pull 请求，以便其他人可以从此修复中受益。
