JGitInternalException while adding files

I just tried to start working with JGit and am now stuck with a strange exception, while doing most basic things.

My code:

public class JGitTest {
    public static void main(String[] args) throws Exception {
        File worktree = new File(
                "C:\\Users\\nils\\Desktop\\tmp\\gittest\\jgittest");
        File repodir = new File(worktree, ".git");

        Repository repository = FileRepositoryBuilder.create(repodir);

        Git git = new Git(repository);
        git.add().addFilepattern(".").call();
    }
}

I get the following exception, when executing this snippet:

Exception in thread "main" org.eclipse.jgit.api.errors.JGitInternalException: Exception caught during execution of add command
    at org.eclipse.jgit.api.AddCommand.call(AddCommand.java:212)

    at org.eclipse.jgit.api.AddCommand.call(AddCommand.java:188)
    ... 1 more

I get a very similar exception, when running this snippet on a Java EE-server. Where is my mistake?

The reason for the JGitInternalException is that there is no repository at the specified location.

Despite its name, FileRepositoryBuilder.create() does not create (i.e. git init) a repository. The FileRepositoryBuilder can only be used to create instances of Repository (the class that represents a repository in JGit) for existing git repositories. Read more on this here.

To initialize a new repository, use

Git git = Git.init().setDirectory( "c:\users\..." ).call();

And don't forget to git.close() the repository once you are done using it.
