Question

在Jenkins流水线中使用Groovy创建带有内容的文件

jenkinsgroovyjenkins-pipelinejenkins-job-dsljenkins-groovy

38

我想要创建一个名为groovy1.txt的文件，内容为“使用Groovy处理文件非常容易”。

注意：我不想使用shell来创建该文件，而是想使用Groovy来实现。

我在我的Jenkins管道中有以下脚本。

node {
def file1 = new File('groovy1.txt')
file1.write 'Working with files the Groovy way is easy.\n'

sh 'ls -l'
// Expecting the file groovy1.txt should present with the content mentioned above
}

但是它会抛出以下的文件未找到（权限被拒绝）错误：

java.io.FileNotFoundException: groovy1.txt (Permission denied)

Jenkins Pipeline提供了writeFile步骤，可用于在作业工作区内编写文件。

请看以下示例：

node {
    writeFile file: 'groovy1.txt', text: 'Working with files the Groovy way is easy.'
    sh 'ls -l groovy1.txt'
    sh 'cat groovy1.txt'
}

运行这个管道脚本会生成以下输出：

[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/test-pipeline
[Pipeline] {
[Pipeline] writeFile
[Pipeline] sh
[test-pipeline] Running shell script
+ ls -l groovy1.txt
-rw-r--r-- 1 jenkins jenkins 42 Jul  8 16:38 groovy1.txt
[Pipeline] sh
[test-pipeline] Running shell script
+ cat groovy1.txt
Working with files the Groovy way is easy.[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

使用 Java 的 File

正如Jon S在评论中提到的，如果你的节点步骤在主节点上执行，那么Java new File("${env.WORKSPACE}/groovy1.txt")将仅仅有效；如果在从节点上执行，则你的管道代码将失败。你可以查阅以下 Stack Overflow 线程以获取更多信息：
