The working directory should be visible on a WebDAV server and none of the parent folders should contain the repository itself.
I want to separate totally the folder for .git and the working directory (on a different drive, clean from project files and others).
Using Eclipse EGIT, the repository creation allows set of working directory (Target Location) within a path within the repository.
No way found to set GIT_DIR or working_directory within Eclipse. Linking not an option (Windows)
The project .location contains the place within the repository (and that is a binary file anyway), so that should be configurable.
Is there any way to move the working directory to a totally different place? Is there a configuration option I have missed? After editing the files, do I really have to push all to the server, then commit to git?
To summarize what has been written in the comments, EGit does not support Git repositories whose work directory is at a different location than the .git directory. I.e. the core.worktree configuration setting is not taken into account.
