在 Jenkins 管道中使用 Groovy 创建一个包含一些内容的文件
Create a file with some content using Groovy in Jenkins pipeline
我正在尝试创建一个名为 groovy1.txt 的文件，其内容为 "Working with files the Groovy way is easy."
注意：我不想使用 shell 创建此文件，而是想使用 Groovy 来实现此目的。
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
}
但它会抛出 FileNotFound（权限被拒绝）错误，如下所示
java.io.FileNotFoundException: groovy1.txt (Permission denied)

Jenkins Pipeline 提供 writeFile 步骤，可用于在作业的工作区内写入文件。
看看下面的例子：
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 此管道脚本生成以下输出：
[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
Using Java File
As Jon S mentioned in the comment, Java new File("${env.WORKSPACE}/groovy1.txt") will work only if your node step is executed on master node - if it gets executed on slave node then your pipeline code will fail. You can check following Stack Overflow thread for more information:
