[FIXED] JGit Check Permissions

Issue

In JGit, is it possible to check developer permissions without doing the actions (provided username and password)?

Ex: Is it possible to check if a user can clone a repository without cloning it?

Ex2: Is it possible to check if a user can push to a repository without pushing to it?

Solution

Ex1

I think, this is not supported by git itself, so no. (I might be wrong though)

As a workaround, one might use CloneCommand#setNoCheckout(boolean) [1], which prevents downloading any branch (clone command should be pretty quick). The cloned repository (cloned into some temp directory), might be removed immediately, if call succeeded.

Ex2

For push, dry-run can be used. Supported by JGit [2].

Most of the commands have some form of dry-run option.

See: Do all git commands have a dry-run option?
