• How do I switch between Java versions?

  There is a useful tool on Linux/Mac called jenv that allows you to set the jvm to use for a directory and its subdirectories. Someone has created a port of that to windows here: https://github.com/FelixSelter/JEnv-for-Windows

• Error when creating a Forge/Fabric Better Minecraft server 1.19.2

  You can use Jenv to manage your different java versions. I would recommend using JDK 11 instead of 8 (since JDK 8 has already ended active support, and therefore should not used in production enviroments) for anything 1.12.2 or lower. Then remove 16 and 18 since those probably won't be supported soon (JDK 18 is ending both active support and security support in 2 months). So you are basically left with JDK 8, 11, and 17. Then set your global java version with jenv to be 17, and for any servers that need 11, just set the local directory to use 11 instead

• I keep getting this error when running the .bat file when trying to start up a new server what's causing this and how do I fix it?

  This error comes up so many times on this sub. The solution is to update to a later java version. You are running Java 8 (Java Bytecode Version 52.0), while what you really need is Java 17 or higher (Java Bytecide Versoin 61.0+). Uninstall Java 8, and then replace it with Java 17. The recommended runtime is Eclipse Temurin or Amazon Corretto. Install either of them (make sure that it is Java 17), and run java --version to double check. If you need to run both Java 8 and 17 on the same system (eg you run a modded 1.12.2 server along with a Paper 1.19 server), then you'll probably want to install JEnv.

  generally, u might need to use a java version manager. This should hopefully allow you to keep your current jdk version, but also switching to another one for the server. a good one is JEnv, which works by switching java versions as needed. For MacOS and Linux, use this one (https://github.com/jenv/jenv), while for Windows, use this one (https://github.com/FelixSelter/JEnv-for-Windows). It's very similar to something like rbenv or nvm, but you have to install the java versions yourself.
