git submodules broken over SSH

[stevendgonzales]

For a repo with submodules, I am getting the below error. Any advice?

It appears this does not work because the command git config --get-regexp ^submodule\\..+\\.url does not work because git submodule update --init as been called.

If I manually run git submodule update --init in the flyweight directory then git config --get-regexp ^submodule\\..+\\.url succeeds, and I then receive a different error:

@srinivasupadhya It looks like submodule checkouts may have been broken in commit 895d9a2
as it was working prior at 9a594cd

[stevendgonzales]

trying to track down root cause, as it appears to come from https://github.com/srinivasupadhya/git-cmd/blob/master/src/com/tw/go/plugin/GitHelper.java

[stevendgonzales]

First exception is related to com.tw.go.plugin.GitHelper.fetchAndReset(GitHelper.java:100) in the git-cmd repo. I have opened an issue and suggested a possible fix that I can implement here: srinivasupadhya/git-cmd#1

[srinivasupadhya]

fixed in git-cmd. Will make new release with update soon.
