[1.7.10] AbstractMethodException while registering new commands (using ant)

I'm writing a mod for 1.7.10. I'm trying to register a new command to interact with my mod. If I compile it via gradle, it works. However, I'm trying to compile it via Apache Ant. I extracted the *.class files from the gradle cache, and put them in my java ClassPath. When I compile, it compiles fine, but when Forge tries to load my mod, I get the following exception:

I can go back through the minecraft source and see that 

func_71560_a

doesn't exist. Any suggestions on how to solve this? I'd prefer to keep compiling with ant.

  • Author

a) why does it matter. I'm comfortable with ant, not gradle - not to mention ant compiles in ~1 second while gradle takes up to 10.

b) I'm not complaining, I'm just looking for help.

c) thanks for the really helpful post.

 

 

Don't bring me into stuff like this, Don't use ant unless you know exactly what you're doing. FG was built for a reason and it's dead simple to use. USE IT!.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
