Missing dependencies

NoClassDefFoundError: eureka/api/EurekaAPI (Missing Eureka Mod)

What the log looks like

java\.lang\.NoClassDefFoundError:\s*eureka/api/EurekaAPI
java\.lang\.ClassNotFoundException:\s*eureka\.api\.EurekaAPI

How to fix it

  1. Download the Eureka mod for Minecraft 1.7.10 from CurseForge and place its .jar file into your Minecraft mods folder.
  2. Check that Buildcraft Additions is updated to the latest 1.7.10 release, as newer builds either properly enforce dependencies at startup or handle missing Eureka compatibility safely.
  3. If you are running a server, install Eureka in both the server and client mods folders before rejoining the world.
