    Building the JDK and getting the HotSpot sources loaded into CLion

As I've already found myself more than once going through the steps of building the JDK on my Ubuntu machine and getting the Hotspot's source loaded into CLion, I ended up deciding to assemble this document to help me or others in the future, would the need eventually arise.
Building the JDK should be relatively painless, and when problems arise the tools are in generally very specific about what's wrong. In the worst of scenarios, a simple google search will most likely suffice. But as there are at least some things we should be wary about, I'm writing this simple tutorial down.

    Bash Cheat Sheet

curl


Pass in username/password: -u username:password, to use github tokens, curl -u 2346b76ab68d28071961d15e96e89d09614bec97:x-oauth-basic
Passing in HTTP headers: -h "A: B", such as -h "Autorization: bearer ABC
Post a message in the body of curl: --data "contents" or -d "contents"
curl will by default assume it's dealing with a GET, unless a -d is passed in, then being considered a POST. To explicitly state which request method you want, you can pass in -X PUT, -X HEAD, etc.
Follow redirects: -L
Avoid reporting download information: -s
Extra information: -v, -i
