I'm using this plugin https://wiki.jenkins.io/display/JENKINS/Bitbucket+pullrequest+builder+plugin as a build trigger, on Jenkins v2.140 and v2.141 it can't update the build status on Bitbucket when the build is finished (either success or failed). But on Jenkins v2.138, it is working just fine. After looking at the source code of that plugin, I believe the problem is related to this file https://github.com/nishio-dens/bitbucket-pullrequest-builder-plugin/blob/master/src/main/java/bitbucketpullrequestbuilder/bitbucketpullrequestbuilder/BitbucketBuilds.java on line 41. On Jenkins v2.140 and v2.141 it seems that it the Jenkins Root URL is null, even though it is not, I already checked the Jenkins Root URL is indeed filled with valid URL. As this plugin is quite critical to my company, can you please take a look on what changed in the latest Jenkins that caused this issue?
