Jenkins Workflow：如何并行执行集成测试

Question

大家好，我一直在处理这个问题，但我找不到解决方案，因为每次都在名为 MyProject@1,2,3,4 的新目录中进行集成测试运行...

我已经声明我希望他们在特定目录中运行但这无济于事。这是我的代码示例。

parallel( FirstSuite: {
    node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 0 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=FirstSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/FirstSuite'
         } 
     }
 }, 
 SecondSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 20 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=SecondSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/SecondSuite'
         }
     }
 },
 ThirdSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 40 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=ThirdSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/ThirdSuite' 
         }
     }
 },
 FourthSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 60 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=FourthSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/FourthSuite' 
         }
     }
 },
 FifthSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 80 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=FifthSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/FifthSuite' 
         }
     }
 },
 SextSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 100 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=SextSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/SextSuite' 
         }
     }
 },
 SeventhSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 120 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=SeventhSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/SeventhSuite' 
         }
     }
 },
 EighthSuite: {
     node('master') {
         ws('/opt/.jenkins/workspace/MyProject') {
             sh 'sleep 140 && mvn -s settings.xml -f java/pom.xml integration-test -P dev  -Dmaven.repo.local=.repository -Dit.test=EighthSuite -Djava.io.tmpdir=java/target -Dlog.dir=java/target/log/EighthSuite' 
         }
     }
 },)

但我仍然在 maven 中收到 pom 不可读的错误，并且该目录丢失，因为这个 ws 命令没有帮助。我的集成测试在 MyProject@2、@3、@4 等中执行...

这是因为您使用了ws步骤。而不是使用 dir，它不检查路径的唯一性。

来自 Jenkins Pipeline Snippet Generator 关于 ws 的帮助提示：

If concurrent builds ask for the same workspace, a directory with a suffix such as @2 may be locked instead. Currently there is no option to wait to lock the exact directory requested; if you need to enforce that behavior, you can either fail (error) when pwd indicates that you got a different directory, or you may enforce serial execution of this part of the build by some other means such as stage name: '…', concurrency: 1.

If you do not care about locking, just use the dir step to change current directory.

此外，如果您的实际意图是在同一节点上执行所有执行流，我建议将 node 移出 parallel。像这样：

node('master') {
    dir('/opt/.jenkins/workspace/MyProject') {
        parallel FirstSuite: { ... },
                 SecondSuite: { ... },
                 <... other suites ... >
    }
}
