From: http://stackoverflow.com/questions/40739694/password-not-saved-in-jira-trigger-configuration

I've installed jira-trigger-plugin which works almost fine. Only thing is, when I add a JQL filter things stop working. In the logs I see "JIRA is not configured in Jenkins Global Settings. Please set the jiraPassword"

And indeed, in /configure, the password field in 'JIRA Trigger Configuration' is empty. When I fill it in, Save it and then reload the page it's empty again. Root URL and Username are stored, password not.

Any ideas??
