 ## Building the merge of Source Branch into Target Branch
 
 You may want Jenkins to build the merged PR (that is the merge of `sourceBranch` into `targetBranch`) to catch any issues resulting from this. To do this change the Branch Specifier from `origin/pr/${pullRequestId}/from` to `origin/pr/${pullRequestId}/merge`
 
 If you are building the merged PR you probably want Jenkins to do a new build when the target branch changes. There is an advanced option in the build trigger, "Rebuild if destination branch changes?" which enables this.
 
-You probably also only want to build if the PR was mergeable and always without conflicts. There are advanced options in the build trigger for both of these.
