BPM DC Build ERROR: Could not set up build infrastructure path list

HI Experts,

i am developing a BPM Development Component, it has no code errors and is very simple. but, when i try to build it, it throws the following error:

*Start build plugin:*

   *ERROR: Could not set up build infrastructure path list:Used component tc/bpem/compiler/base(SC null) not available*

   *Build failed with errors.*

I have already set in NWDI the required dependencies according to SAP notes. Apparently there is anotehr dependency, or i dont know.

any Sugestion about it?

thanks
