无法通过Jenkins上的管道作业的jenkinsfile中的Groovy代码(或java代码)创建文件

Question

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                echo 'Building..'
                echo "whoami".execute().text
                script {
                    File f = new File('/home/jenkins/test2.txt');
                    f.createNewFile();
                }
            }
        }
        stage('Test') {
            steps {
                echo 'Testing..'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deploying....'
            }
        }
    }
}

这是因为Jenkins没有实现Groovy本身而是一个解释器(CPS) - https://github.com/cloudbees/groovy-cps

为了帮助处理所引入的复杂性,已经实施了一些常见步骤来解决诸如创建文件之类的任务.

要使用开箱即用的Jenkins管道步骤,请使用writeFile:https://jenkins.io/doc/pipeline/steps/workflow-basic-steps/#code-writefile-code-write-file-to-workspace

writeFile([file: 'file.txt', text: filetxt])

如果你自己写的是死的,我建议把它拆分成一个共享库,注意这可能会导致需要批准的ScriptSecurity警报:

final class PipelineUtils implements Serializable {
    private script=null
    private static final PipelineUtils instance = new PipelineUtils()
    @NonCPS
    String saveFile(String filename, String text) {
        String PWD = script.pwd()
        String filePath = "${PWD}/${filename}"

        File file = new File(filePath)
        file.text = text
    }
}

有关@NonCPS和非可序列化对象的信息,请参阅https://github.com/jenkinsci/pipeline-plugin/blob/master/TUTORIAL.md.
