Mismatch between git clone and JGit's cloneRepository [message #1854845]

I'm trying to replicate the suggestion in this stackoverflow answer:
https://stackoverflow.com/a/65464092
Basically I tried to replicate

git clone --no-checkout --depth 1 <repo>

with

Git.cloneRepository()
			.setURI(REMOTE)
			.setDirectory(localPath)
			.setDepth(1)
			.setNoCheckout(true)
			.call();

But, instead of showing a list of the files in the repo,

git ls-tree -r HEAD

gives me

fatal: Not a valid object name HEAD

The main difference I see between the files checked out by git/JGit
in .git/ is that in the JGit's version .git/ref/heads/master is missing (while still being referenced in .git/HEAD).
Is there any parameter I'm missing to make this thing work as expected? Thanks.

No, there is no parameter missing. JGit only sets HEAD correctly if it does a checkout. This might be a bug in JGit, possibly the same as bug 438013. Looks like JGit's CloneCommand should set HEAD in any case, whether it'll do a check-out or not.

The problem with HEAD should be fixed in JGit 6.4.0-SNAPSHOT. But note bug 580769 for a (minor) difference in behavior for shallow clones.

Thanks to all of you.
Is there a maven repo for snapshot versions?

Try https://repo.eclipse.org/content/repositories/jgit-snapshots/ .
