Re: git fails updating submodule only if --quiet is specified

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I did a bunch more investigation:

My original problem was that it would work on a terminal, but not when running under jenkins.

Turns out the “-v” in the "index-pack” step is whats leading to the error.

I can reproduce the issue with the command "git submodule update --init --recursive > out.txt 2>&1"

It seems that the “-v” is dropped automatically by git if its not connected to a terminal.

This is only an issue for “git://“ urls. ssh and https seem to not be affected.
