!MESSAGE Warning: EGit couldn't detect the installation path "gitPrefix" of native Git. Hence EGit can't respect system level
Git settings which might be configured in ${gitPrefix}/etc/gitconfig under the native Git installation directory.
The most important of these settings is core.autocrlf. Git for Windows by default sets this parameter to true in
this system level configuration. The Git installation location can be configured on the
Team > Git > Configuration preference page's 'System Settings' tab.
This warning can be switched off on the Team > Git > Confirmations and Warnings preference page.

user global configuration and to define the default location to store repositories: 'C:\Users\vy.vy-pc'. If this is

EGit might behave differently since they see different configuration options.
