在我的詹金斯管道中,我正在使用Pipeline Utility Steps插件读取存储在yaml文件中的数据
我可以从文件中读取数据,现在我想更新该值并将其写回到文件中,如下所示:
pipeline {
agent any
stages {
stage('JOb B ....'){
steps{
script{
def datas = readYaml file:"${WORKSPACE}/Version.yml"
echo datas.MAJOR_VERSION //output is 111
datas = ['MAJOR_VERSION': '222']
writeYaml file:"${WORKSPACE}/Version.yml", data: datas
}
}//steps
}//stage
}//stages
}//pipeline
但是我遇到了错误-Version.yml已经存在:
java.nio.file.FileAlreadyExistsException: /var/lib/jenkins/workspace/t-cicd-swarm-example_hdxts-job-B/Version.yml already exist.

似乎只能写一个新文件,不能覆盖现有文件。如何从上面显示的脚本更新现有yaml文件的内容?

由于writeYaml方法没有覆盖标志,因此您似乎需要删除或重命名原始文件,然后再覆盖它。
sh '''
if [ -e Version.yaml ]; then
rm -f Version.yaml
fi
'''

根据最新文档。您可以使用一个参数来覆盖指定文件的内容:
writeYaml: Write a yaml from an object.
...
overwrite (optional): Allow existing files to be overwritten. Defaults to false.
