Git plugin for Hudson checkout problem

Question

When using the Git plugin for Hudson my job always fails when fetching the latest sources from my online git repository ( git://github.com/ithena/orm2dsl.git ) .

The git plugin first executes git fetch succesfully. Then it tries to execute git checkout -f origin/ , which fails as shown below. Is this a problem with my git repository or is it the checkout command that makes no sense?

Git command whithout a branch set in the job configuration:

git checkout -f origin/
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'origin/' which can not be resolved as commit?

Git command with branch set to master in the job configuration:

git checkout -f origin/master
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'origin/master' which can not be resolved as commit?

Hudson console output:

started
Checkout
[workspace] $ git fetch
Checking out origin/
[workspace] $ git checkout -f origin/
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'origin/' which can not be resolved as commit?
FATAL: Error checking out origin/

Answer 1

First, your version of Git is pretty old. I suggest you update it before you do anything else.

Second, git checkout -f origin/ is not a valid command. You either need to checkout a branch, or you can checkout a commit (by specifying the commit hash or a tag) and create a new branch of it at the same (using git checkout -b new-branch commit-hash). See the git-checkout man page for further details.
