推荐答案

您可以使用 properties 方法，该方法嵌套在 BuildDiscarderProperty 中，最终拥有您想要的键放.我仍然没有可靠的方法来查找每个键的正确语法.经过多次猜测和检查:

You can use the properties method which, nested within the BuildDiscarderProperty eventually has the key you want to set. I still don't have a solid way to look up the correct syntax of each key. After much guessing and checking:

properties([[$class: 'BuildDiscarderProperty', strategy: [$class: 'LogRotator', artifactDaysToKeepStr: '', artifactNumToKeepStr: '', daysToKeepStr: '', numToKeepStr: '10']]]);

请注意，此代码段适用于脚本语法.
