If you download the installer that usually comes in a msi installer it should then Autodetect it. More on reddit.com

I have the same situation and I use https://github.com/jdx/mise - multiple languages and multiple versions. Best of all, mise can understand the language-specific tool configuration file (as opposed to introducing yet another config file that the whole team needs to be watchful of when upgrading versions) More on reddit.com

Java 15 is the current LTS ("long-term support") version

No it is not. Java 15 is only updated/patched until next release, which means for 6 months. LTS is something a company chooses to support for a long period of time. Oracle supports Java 8, Java 11, Java 17 (next LTS). Same for Redhat. I think Azure support Java 14 as LTS as well.

In general, you will find that AdoptOpenJDK is a go-to choice for obtaining the JDK.

You should go to official OpenJDK site to get your JDK.

Lombok

Section on Lombok. I would add a big warning or note. If you're promoting newest Java versions, I guess you know, that records have landed and in Java 16 they will be a standard feature. Combine it with upcoming withers and you can write:

record Point(int x, int y) {}
Point p;
Point pp = p with { x = 3; }

Lombok has a lot of problems, funnily enough, it broke IntelliJ recently and they had to do an emergency patching.

P.s. I can make a pull request for these suggested changes.
