Why do these jar files occur in my 'Unvefrsioned Files'?
已回答
I have been using the community version, and just switched to the enterprise version for a try. Why do these jar files occur in my unversioned files? Should I add the /lib directory to my .gitignore file? I didn't do this before and it has been working file.
Please use the screen shot.
Thanks,

Yes, you can add the lib directory to .gitignore. It looks like some project wizard has downloaded and placed these files into the lib directory.
Since your project is Maven based, you don't need these manually configured dependencies. See also https://intellij-support.jetbrains.com/hc/articles/206544839.
Thanks.
