Please ask questions on the mailing lists. Refer to http://jenkins-ci.org/content/mailing-lists for the names, addresses, and descriptions of the mailing lists.
Many more users read the mailing lists than read individual bug reports, so you have a much better chance of finding an answer to a question through the mailing list rather than through a bug report.
Since Jenkins is an open source project, many of the developers and testers and subscribers are using their personal time to support the project. By using a bug report that is only read by a few people, you're trying to persuade those who actively read git client plugin bug reports (a very few people) to answer your questions, instead of investigating and resolving bugs or adding features. If you ask the question on the mailing list, you're trying to persuade a much larger group of people to use their personal time to assist you.
Please use the jenkins-dev mailing list for questions specific to your installation, rather than submitting a bug report asking the question.
