How to develop in intellij?

OS: OSX
JAVA version: 8
SPARK version: 3.3.1
Hi team, I have been trying to setup raydp code base in intellij. I was able to build the repo, but all the test cases seem to fail. Also I had to copy all the built jars to python/raydp, is it the right way to setup? There doesn't seem to be a good "how to contribute section" in the docs. Can someone please share their dev setup steps?
