After 4.7.3 upgrade, Eclipse thinks my git config is in a different place [message #1784148] Thu, 22 March 2018 23:35 Go to next message

In the past, I've noticed some oddities in the git configuration dialog. I have my .gitconfig in "C:\Users\<myuid>", but I often find eGit thinks it's in "H:\". When I've seen this in the past, I was simply able to change the path in the field to the correct one, and it would be fine for a while.

After the 4.7.3 upgrade, it appears that I can't even change this now.

I do have one environment variable that refers to that location, called "HOMEDRIVE". I find it hard to believe eGit uses that.

How do I get eGit to use the config location that I want?

Is it using the "HOME" environment variable? I'm trying not to set that, because that confuses Cygwin.

As you see below JGit on windows (if cygwin is not used) is using 1) HOME, 2) HOMEDRIVE/HOMEPATH and 3) HOMESHARE. Be aware that if cygwin is used than the code is again different (see FS_Win32_Cygwin#userHomeImpl())

Thanks, but that only confirms that I don't have any choice. I now have a handful of identical .gitconfig files littered around because my tools won't let me specify a single location for it.

What would you suggest? If the $HOME variable is not set how should (j)git find the users .gitconfig file?

Well, from the perspective of Eclipse, simply let them specify the location in a config property.

I think we should find a solution for JGit which is not Eclipse specific. Which of the environment variables HOME, HOMEDRIVE, HOMEPATH, HOMESHARE are set in your environment and how is the system property user.home set in your eclipse. If the code I attached doesn't find enough info in the listed environment variables it will call FS#userHomeImpl(). And this will use the standard system property "user.home". So maybe setting the system property "user.home" in eclipse.ini is sufficient.
