Thanks for your answer, but sadly it still doesn't work. Without minecraftLibrary I can't even build the mod and with it I still get the same error.

Hello, I have this lines in my build.gradle, but when I build the mod and start Minecraft with the mod in Modrinth it says Can anyone help me with this problem? jarJar.enable() dependencies { minecraft "net.minecraftforge:forge:${minecraft_version}-${forge_version}" annotationProcessor("org.spongepowered:mixin:0.8.5-SNAPSHOT:processor") // Forge"s hack fix implementation("net.sf.jopt-simple:jopt-simple:5.0.4") { version { strictly "5.0.4" } } // WebSocket minecraftLibrary "org.java-websocket:Java-WebSocket:1.5.3" jarJar(implementation("org.java-websocket:Java-WebSocket:1.5.3")) }
