By default the ResetCommand resets to HEAD. To reset to another branch, you need to specify this branch with setRef().

For example:

git.reset().setMode(ResetType.HARD).setRef("refs/heads/level1").call();

The above command will let the current branch point to the latest commit of level1 and checkout its state into the work directory .
