Dirty Paws

Okay, It is fixed, I can start it with a bat file. My bad.

I am starting the server by clicking the forge jar file. And this is the outpot of a version check.

That's what I gathered from searching the topics, but I specifically checked (and checked again right now, just to be sure) : I am using Java 8 version 241.

This is the crash log I get: java.lang.ExceptionInInitializerError: null at net.minecraftforge.fml.ModLoader.<init>(ModLoader.java:121) ~[?:?] {re:classloading} at net.minecraftforge.fml.ModLoader.get(ModLoader.java:146) ~[?:?] {re:classloading} at net.minecraftforge.fml.server.ServerModLoader.begin(ServerModLoader.java:45) ~[?:?] {re:classloading} at net.minecraft.server.dedicated.DedicatedServer.func_71197_b(DedicatedServer.java:122) ~[?:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:613) [?:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at java.lang.Thread.run(Thread.java:830) [?:?] {} Caused by: java.lang.IllegalStateException: Failed to resolve consumer event type: net.minecraftforge.fml.network.simple.SimpleChannel$$Lambda$2682/0x0000000801448840@6ca99413 at net.minecraftforge.eventbus.EventBus.addListener(EventBus.java:194) ~[eventbus-2.0.0-milestone.1-service.jar:?] {} at net.minecraftforge.eventbus.EventBus.addListener(EventBus.java:161) ~[eventbus-2.0.0-milestone.1-service.jar:?] {} at net.minecraftforge.eventbus.EventBus.addListener(EventBus.java:156) ~[eventbus-2.0.0-milestone.1-service.jar:?] {} at net.minecraftforge.eventbus.EventBus.addListener(EventBus.java:151) ~[eventbus-2.0.0-milestone.1-service.jar:?] {} at net.minecraftforge.fml.network.NetworkInstance.addListener(NetworkInstance.java:65) ~[?:?] {re:classloading} at net.minecraftforge.fml.network.simple.SimpleChannel.<init>(SimpleChannel.java:57) ~[?:?] {re:classloading} at net.minecraftforge.fml.network.simple.SimpleChannel.<init>(SimpleChannel.java:50) ~[?:?] {re:classloading} at net.minecraftforge.fml.network.NetworkRegistry$ChannelBuilder.simpleChannel(NetworkRegistry.java:409) ~[?:?] {re:classloading} at net.minecraftforge.fml.network.NetworkInitialization.getHandshakeChannel(NetworkInitialization.java:38) ~[?:?] {re:classloading} at net.minecraftforge.fml.network.FMLNetworkConstants.<clinit>(FMLNetworkConstants.java:48) ~[?:?] {re:classloading} ... 6 more It is a completly fresh forge server without mods.
