Git pull - fatal: read error: Invalid argument

Question

I'm trying to pull using msysgit 1.8.1 (tried with 1.7.10 and .11, too, with the same result) and always get an error which I don't know how to debug/resolve:

E:\java\myproject>git pull

Fetching submodule src/jgit/main
fatal: read error: Invalid argument

E:\java\myproject>

Between

Fetching submodule src/jgit/main

and

fatal: read error: Invalid argument

it takes approximately 5min (timeout?).

What also is strange, that one line starts with rRemote - a bug in msysgit?

Answer 1

Cloning/pulling from ssh://myserver:12345/myproject works well.

But pulling from the url recorded in the .gitmodules file of that repo, for the submodule "src/jgit/main" doesn't.

Check said url, and see if another protocol (https instead of ssh for instance) might work (again, for the url of the submodule, as specified in the .gitmodules file of the repo you just pulled).

Answer 2

I found the reason: the submodule src/jgit/main had two externals. origin pointed to the official jgit repository and another to our clone of the jgit repository. After removing origin and renaming the other to origin, it works. Looks like I had problems pulling from the official jgit repository.
