Error when setting up a server

[Lord Zwieback]

I'm trying to set up a minecraft forge server, but when I try to open the run.bat file to create all the different files the window does appear but only this is displayed:

Error occurred during initialization of boot layer
java.lang.module.FindException: Error reading module: libraries\cpw\mods\bootstraplauncher\1.1.2\bootstraplauncher-1.1.2.jar
Caused by: java.lang.module.InvalidModuleDescriptorException: Unsupported major.minor version 60.0

I'm not really into this kind of stuff so please someone help me

Depending on the minecraft version you are attempting to run:

- 1.18 and later need Java 17

- 1.17 needs Java 16

- 1.16.5 and older need Java 8

Resolving the same problem, but I am sure that on the hosting system Java 17 is installed, by running ./java -version

openjdk version "17.0.6" 2023-01-17 LTS
OpenJDK Runtime Environment Zulu17.40+19-CA (build 17.0.6+10-LTS)
OpenJDK 64-Bit Server VM Zulu17.40+19-CA (build 17.0.6+10-LTS, mixed mode, sharing)

is this build somehow outdated or incompatible with 1.19.2 Forge  43.1.52, or 43.2.3, neither of them won't runs, both with error:

First, don't post on other people's threads unless you are helping the original poster. Start your own thread.

As often as you not, you might have the same error message but for a different reason.

 

The error message says you have code compiled for java 16 (major=60), but the version of java you are actually using doesn't support it.

https://stackoverflow.com/questions/9170832/list-of-java-class-file-format-major-version-numbers

i.e. you are using a java implementation earlier than java 16.

So whatever java you are starting forge with, it is not that java 17.

 

./java means use the java executable in the current folder

the run.sh by default use the java specified on the PATH environment variable

a quick way to find out what that is by typing

which java

 

[warjort]

And an easy way to fix it, is to change the run.sh

Replace where it says java with the full path to that java 17 executable
