Recommended Posts

When building my mod with Forge 1.8 Build 1273 I'm getting this AbstractMethodError crash when trying to use the mod in normal minecraft. Both my enviroments are with Forge Build 1273 and the mod runs fine within Eclipse.

 

Sourcecode of EnumOrganicLayer.java

 

Exception:

The problem is that your

IEnumState

interface has a

getName

method, which Minecraft's

IStringSerializable

has as well. Because

IStringSerializable

is a Minecraft class, it has obfuscated names outside the development environment, so

getName

is not actually called

getName

outside of eclipse. Because

EnumOrganicLayer

implements

IStringSerializable

, it's

getName

is renamed to what Minecraft's

getName

is actually called when you build your mod ("reobfuscating"). But the

getName

method of

IEnumState

is not renamed of course, so

EnumOrganicLayer

has a missing method at runtime.

 

Wow ok, you're a genius, anybody mentioned that already? ;-)

Thank you for your help!
