It is an important use case in our organization to have ability to do shallow clone of git repositories.
Does the current implementation of JGit allow shallow clone?

Some of the Replies and Bugs regarding Shallow Clone :

This is fixed based on this BUG Log
https://bugs.eclipse.org/bugs/show_bug.cgi?id=301627

But as of a StackOverFlow link which is dated on Aug 2012 it isnt working yet
I am unable to paste the link here .. please do visit StackOverFlow and search for Shallow Clone in JGIT

Regards
Malai

If we try to load an existing shallow clone, JGit crashes with error as shown below.

"Could not create the view: Walk failure.".

It is missing the parent commit of the deepest commit in the shallow clone:

Error log below:
