如何编写管道以丢弃旧版本? [英] How to write Pipeline to discard old builds?

问题描述

groovy语法生成器不适用于示例步骤properties: Set Job Properties.我选择了Discard old builds，然后在Max # of builds to keep字段中输入了10，然后选择了Generate Groovy，但没有任何显示.

The groovy syntax generator is NOT working for sample step properties: Set Job Properties. I've selected Discard old builds and then entered 10 in the Max # of builds to keep field and then Generate Groovy and nothing shows up.

推荐答案

您可以使用properties方法，该方法嵌套在BuildDiscarderProperty中，最终具有您要设置的密钥.我仍然没有可靠的方法来查找每个键的正确语法.经过大量的猜测和检查:

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化语法.
