Git Works Out of the Box in Hudson; Can't Even Install Plug-In in Jenkins

So after reading multiple Q&As here about why I should use Jenkins over Hudson, I went ahead and made the switch ... and now I'm regretting it. With Hudson (or at least with the Debian package I used to install Hudson), Git came "out of the box"; I didn't have to install any plug-ins or anything.

With Jenkins however, not only do I need a separate plug-in, but when I try to install that plug-in, it fails, repeatedly. I can find th开发者_高级运维e plug-in in the list of available plug-ins, check it, and get a "success" message, but after I restart Hudson the plug-in isn't there (and it's once again on the available plug-ins list).

The problem might be the warning message under the plug-in's description:

Warning: This plugin is built for Jenkins 2.1.0 or newer. It may or may not work in your Jenkins.

... except there is no 2.1.0 of Jenkins (or even a 2.anything), at least that I can find.

Has anyone else run in to this, and if so do you have any kind of workaround?

I wound up purging hudson/jenkins, then re-installing the jenkins package; this time the git plug-in installed successfully!
