So I've installed MCP and Forge and Eclipse, got everything set up, and started writing my mod.  I can hit the green Run button in Eclipse, Minecraft pops up, I can start a world, and see my new blocks and items.  Wonderful!

 

The problem is I'm writing a tech mod, and I'd like it to integrate with Buildcraft in general, and Thermal Expansion in particular.  So what I want is to not just have my mod loaded by Eclipse, but also Buildcraft and Thermal Expansion, so I can test whether, eg, my new ingots can be processed in TE machines quickly and easily.

 

I grabbed the Buildcraft source, dumped it into my src folder, and it seems to work.  But Thermal Expansion is closed source (and depends on a closed source coremod, CoFHCore to boot).  I don't want to decompile it or modify it in any way, I just want it to run so I can spawn in some TE blocks to see if they work properly with my mod, *without* needing to actually properly build my mod, obfuscate it, and fire up my actual minecraft install.

 

I heard the BON tool might help, but the closest I can get is a crash on load with this message:

Help? 

Update to the newest forge, and put CodeChickenCore (dev or compiled) into your forge/mcp/jars/mods/ folder. Then you can add any compiled mods into the mods folder you want and play with them.

Holy crap, that's awesome.

 

I haven't tested it yet, but if it works as described, that solves all my problems!
