I have no label on my side. Currently:

• PR are built when a new commit is pushed
• PR are not built when there are created or when we request a build through a comment

Hi, I am also suffering from this issue. I’m using Github Enterprise 2.8 with Github Pull Request Builder plugin 1.33.2 (but, this also occurs at the master branch)

In my opinion, this is more complex issue because it related to github-api. This error is occurs at this point ( https://github.com/jenkinsci/ghprb-plugin/blob/master/src/main/java/org/jenkinsci/plugins/ghprb/GhprbPullRequest.java#L365 ) by calling listCommits.

But, github’s hook returns api url /repos/:user/:repo/issues/:pr_number not /repos/:user/:repo/pulls/:pr_number.

github-api project’s GHPullRequest implements are ( https://github.com/kohsuke/github-api/blob/master/src/main/java/org/kohsuke/github/GHPullRequest.java#L250 ). At this point, we neither could modify PR’s api url nor call user defined url.
