I have been trying to build the dimdim source code (V2.0) using the following file " DimDimCodeBase\v2.0\Product\Build\building_pack_on_windows " but the error " BUILD FAILED " is ocurring . i am using the following for building :

Jdk 1.5
Ant 1.7

Can anybody tell me the possible reasons for this error and how it can be resolved..i will be very thankful to him/her.
