我可以获取内容,但如何将其重新写回?

I can get the content, but how can I write it back again?
我想到的一种方法是对文件执行 sed
.但我认为这不是很准确.
One way that comes to my mind would be to do a sed

推荐答案
管道实用程序Steps 插件具有与 YAML 文件交互的 readYaml
和 writeYaml
步骤.writeYaml
默认不会覆盖你的文件,所以你必须先删除它.
The Pipeline Utility Steps plugin has the readYaml
and writeYaml
steps to interact with YAML files. writeYaml
will not overwrite your file by default so you have to remove it first.
def filename = 'values.yaml'
def data = readYaml file: filename
// Change something in the file
data.image.tag = applicationVersion
sh "rm $filename"
writeYaml file: filename, data: data
