Can't build

[QuintenQVD0]

**Building the project gives a class file version error ** when compiling the plugin i get a error off: bad class file: /home/pi/.gradle/caches/modules-2/files-2.1/org.bukkit.craftbukkit/1.17/1.17/92a039b1e307af55262e6af94cdab7eef69bd958/1.17-1.17.jar(net/minecraft/core/IRegistry.class) class file has wrong version 60.0, should be 52.0 Please remove or make sure it appears in the correct subdirectory of the classpath.

To Reproduce Steps to reproduce the behavior:

1. install java 8 on linux and gradle
2. go in to the /React folder
3. run gradle clean build
4. See error

Expected behavior the class file shoud have version 52.0

Minecraft 1.17 requires Java 16. Compiling on Java 8 will not work.
