Trouble with recompiling a mod addon

[Alexiy]

I'm trying to make a Buildcraft addon. The buidcraft is in my project as a Jar. I have some classes that extend buidcraft classes. When I recompile, I get many errors:

The MCP recompiler doesn't know that you're using a .jar. Everything that has to be recompiled should be in the mcp/src folder. So I think the solution would be to download the dev version from the Buildcraft Github, and add it to the mcp/src folder. Yes, this will output the Buildcraft mod as well in the mcp/reobf folder, but you can just leave it there.
