When using v1.66 of the job-dsl-plugin the postBuildScripts plugin can be used as follows:

job {
  publishers {
    postBuildScripts {
      onlyIfBuildSucceeds(true)
      onlyIfBuildFails(true)
      steps {
         ... build steps ...
      }
    }
  }
}

The problem is that due to how results are migrated from the old XML style to new (See: https://github.com/jenkinsci/postbuildscript-plugin/blob/9e7a84a29a3b48b93f18606a7eaea22f03f5013a/src/main/java/org/jenkinsci/plugins/postbuildscript/PostBuildScript.java#L143-L152) the only values which can be set are SUCCESS or FAILURE using the job-dsl-plugin

I would like to also run my post build steps if a job is ABORTED for example but there is no API to do this.
