Compatibility problems on Linux

[lordfeck]

Greetings,

I've tried running the jarfile on both Debian and Void Linux. Unfortunately, in either case, I get a similar error on startup:

$ java -jar Microcraft_10.jar 
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: com/jdh/microcraft/Main has been compiled by a more recent version of the Java Runtime (class file version 58.0), this version of the Java Runtime only recognizes class file versions up to 52.0

On Void at least, my Java version is:

$ java -version
openjdk version "1.8.0_272"
OpenJDK Runtime Environment (build 1.8.0_272-b02)

I might have better luck compiling the source myself, but I thought I should raise the issue nonetheless.

Hey there,

This isn't actually a compatibility issue, you just have an outdated JRE. You'll need to upgrade to the latest (Java 14+) to run things. I would give instructions, but they'll vary depending on your selected flavor of Linux. I'll note this in the documentation.
