using Minecraft 1.7.10 (modpack Tekkit Legends)
using MatterLink MatterLink-1.7.10-1.6.3.jar in mods folder.
matterbridge is running and also working between telegram and discord. MatterLink now should be added to the pipe.
But when the Minecraft Server starts, the error
java.lang.NoSuchMethodError: org.apache.logging.log4j.Logger.info(Ljava/lang/String;Ljava/lang/Object;)V
occures.
Is there no log4j compiled in the jar? How to add such a specific dependency?
