BuildCraft Additions Crash When Opening Inventory (EurekaAPI)

What the log looks like

java\.lang\.NoClassDefFoundError:\s*eureka/api/EurekaAPI
buildcraftAdditions\.compat\.eureka\.BCAEurekaEvents\.onGettingAchievement
java\.lang\.ClassNotFoundException:\s*eureka\.api\.EurekaAPI

How to fix it

  1. Install the Eureka library mod (by AEnterprise) for Minecraft 1.7.10 into your mods folder so eureka.api.EurekaAPI is available.
  2. Update BuildCraft Additions to its latest 1.7.10 version (2.2.5 or newer), which fixes crashes when Eureka is not present.
  3. If Eureka is already installed and the log still shows ArrayIndexOutOfBoundsException during class loading, re-download a fresh copy of Eureka and remove custom jar coremods such as da3dsoulASMFix that can corrupt class loading.
  4. If you do not need BuildCraft Additions in your modpack, remove the BuildCraft Additions jar from your mods folder.
