jenkins - 如何使用 Jenkins 管道写出环境变量

Question

如何在 Jenkins 管道中使用 writeFile 写出环境变量？这似乎是一项简单的任务，但我找不到任何关于如何让它工作的文档。

我尝试了 $VAR、${VAR} 和 ${env.VAR}，没有任何效果...？

Answer 1

在声明式管道中(为 writeFile 使用脚本 block )它看起来像这样:

pipeline {
    agent any

    environment {
        SENTENCE = 'Hello World\n'
    }

    stages {
        stage('Write') {
            steps {
                script {
                    writeFile file: 'script.txt', text: env.SENTENCE
                }
            }
        }
        
        stage('Verify') {
            steps {
                sh 'cat script.txt'
            }
        }
    }
}

输出:

...
[Pipeline] { (Verify)
[Pipeline] sh
[test] Running shell script
+ cat script.txt
Hello World
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

如果你想避免 groovy，这也行:

writeFile file: 'script.txt', text: "${SENTENCE}"

要将您的环境变量与您可以执行的文本结合起来:

...
environment {
    SENTENCE = 'Hello World'
}
...

writeFile file: 'script.txt', text: env.SENTENCE + ' is my newest sentence!\n'
