Error when setting up a server

Posted December 19, 20222 yr

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

Quote

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is this build somehow outdated or incompatible with 1.19.2 Forge 43.1.52, or 43.2.3, neither of them won't runs, both with error:

Thanks for any ideas.

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

Boilerplate:

If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one.

If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install

Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

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

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)

[1.21.3] How to add effects to food?

game changed the way you create foods.
for example minecraft 1.21.8 code for the golden apple is

Foods.java
public static final FoodProperties GOLDEN_APPLE = new FoodProperties.Builder().nutrition(4).saturationModifier(1.2F).alwaysEdible().build();

Items.java
public static final Item GOLDEN_APPLE = registerItem("golden_apple", new Item.Properties().food(Foods.GOLDEN_APPLE, Consumables.GOLDEN_APPLE));

Consumables.java
public static final Consumable GOLDEN_APPLE = defaultFood() .onConsume( new ApplyStatusEffectsConsumeEffect( List.of(new MobEffectInstance(MobEffects.REGENERATION, 100, 1), new MobEffectInstance(MobEffects.ABSORPTION, 2400, 0)) ) )
