I share my Windows 10 filesystem with the Windows Subsystem for Linux. I keep my coding projects in the dev folder in my user directory, and share that to /mnt/c/Users/Conan/dev in WSL. Intellij runs projects from the Windows filesystem, but I use a range of command-line tools to run things (such as java) from the share in WSL.
When I start Intellij it says:
Filesystem Case-Sensitivity Mismatch
The project seems to be located on a case-sensitive file system.
This does not match the IDE setting (controlled by property "idea.case.sensitive.fs")
Is this correct? My Windows filesystem is not case-sensitive, but the files were created from bash in WSL. Which setting should I use?
Better solution than making the Linux directory case-insensitive. Make the Windows directory you are using case-sensitive. See https://blogs.msdn.microsoft.com/commandline/2018/02/28/per-directory-case-sensitivity-and-wsl/
This makes for a more complete Linux experience and avoids interop issues such as described here.
In addition, I recommend utilizing the metadata option available in build 17134 (April Update or 1803) or newer for Windows via wsl.conf (manually create in /etc). This will allow your windows directories to keep the permissions assigned by the linux distro you're running with WSL.
