Jenkins Groovy-使用来自readYaml的修改后的数据写回yml文件

jenkins

我正在使用Jenkins readYaml读取数据,如下所示:

data = readYaml file: "test.yml"
//modify
data.info = "b"

我想将此修改后的数据写回到Jenkins中的test.yml。如何做到这一点?

test.yml:

data:
  info: change me
  aaa: bbb
  ddd: ccc

管道脚本:

@Grab('org.yaml:snakeyaml:1.17')
import org.yaml.snakeyaml.Yaml
import org.yaml.snakeyaml.DumperOptions
import static org.yaml.snakeyaml.DumperOptions.FlowStyle.BLOCK

node {
    def yaml = readYaml file: "test.yml"
    yaml.data.info = 'hello world!'
    writeFile file:"test.yml", text:yamlToString(yaml)
}

@NonCPS
String yamlToString(Object data){
    def opts = new DumperOptions()
    opts.setDefaultFlowStyle(BLOCK)
    return new Yaml(opts).dump(data)
}

最终test.yml:

data:
  info: hello world!
  aaa: bbb
  ddd: ccc
