Question

Java

I create a minecraft server on a VPS server according to the guide .

When executing the command java -Xmx1024M -Xms1024M -jar server.jar nogui, an error is displayed:

Error: A JNI error has occurred, please check your installation and try again

Java version:

openjdk version "1.8.0_302"
OpenJDK Runtime Environment (build 1.8.0_302-b08)
OpenJDK 64-Bit Server VM (build 25.302-b08, mixed mode)

I understand that the problems are in some versions of Java. Can you give step by step instructions? I have macos

Answer 1

Class File Versions
That is, the server is compiled for java 16, and you have 8 installed. What are the instructions here? Take down 8, put in 16.
