Which NetBeans projects files should go into source control?

We normally use Eclipse for a particular Java project, but recently I imported the project into NetBeans to use its dialog building features.

Since I'll probably come back to this, I wanted to store the NetBeans project files into version control. However, I don't want to commit files that are "mine" versus "project", i.e., files with my own settings that would conflict with another user's.

NetBeans created the following structure in the top-level project area:

nbbuild
nb-build.xml
nbproject
    <various files>
    configs
    private

Clearly nbbuild is build output, so that won't go in. The nb-build.xml file seems likely, as does most of nbproject. However, nbproject/private suggests it's "mine". Peeking at "configs", it's not clear to me if that's mine or project...

Anyone have some guidelines?

Solution

The NetBeans knowledge base article on project files & version control discusses the NetBeans project files, with loose advice about which files are project specific (i.e. can be shared via version control), and which are user specific.

Here is the section on version control:

If the project is checked out of a version control system, the build (or nbbuild), dist (or nbdist), and the nbproject/private folders should not be checked into that version control system.

If the project is under the CVS, Subversion, or Mercurial version control systems, the appropriate "ignore" files are created or updated for these directories when the project is imported.

Though nbproject/private should be ignored, nbproject should be checked into the version control system. nbproject contains project metadata that enables other users to open the project in NetBeans without having to import the project first.
