How to write Pipeline to discard old builds?

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.

Jenkins version: 2.7

Solution

  • 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']]]);

    Note that this snippet is for scripted syntax.
