Hi, all. I have the Mercurial plugin<https://wiki.jenkins-ci.org/display/JENKINS/Mercurial+Plugin>installed and have been using it successfully for a long time. Recently, I began to notice that on-demand polling was not working correctly. That is, on my Mercurial central repo, I have a hook set up as follows: [hooks] changegroup.jenkins=curl http://server:port/mercurial/notifyCommit?url=ssh://scm//path/to/repo
This was suggested on the plugin's home page and mostly works pretty well. However, sometimes it would fail to trigger polling, and a build would not be started when it was supposed to be. I upgraded to version 1.44 of the plugin, since it looked like this version and version 1.43 had some changes that would fix the issue. The issue was fixed, and polling is now triggered correctly; however, I have a new problem. When a user pushes from the command line interface, they may either get a stuck SSH process or the following NullPointerException: ----- bash-4.1$ hg push pushing to ssh://scm//path/to/repo searching

message is not so bad, but it's alarming for many users; and the hung command line is especially nerve-wracking. Anyone else seen this? I couldn't find anything about it in Jira. Thanks, -- Jerry -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
