I found DtoClientImpls class has been compiled into:
~/works/gitroot/collide/bin/classes/works/gitroot/collide/bin/gen/com/google/col
lide/dto/client
however, it should have been compiled into :
~/works/gitroot/collide/bin/classes/com/google/collide/dto/client

Is there something env vars which need to be set before? or there are some 
problem with build.xml?

What version of the product are you using? On what operating system?
OS: ubuntu 12.04 
      Apache Ant(TM) version 1.8.2 compiled on December 3 2011
     OpenJDK Runtime Environment (IcedTea7 2.1.1pre) (7~u3-2.1.1~pre1-1ubuntu3)

I have finally found the resolution of this problem. This problem is cause by 
the line in build.xml like this:
   "<arg value="--package_base=gen/"/>"   
and in my path string 
"/home/ligen/works/gitroot/collide/bin/gen/com/google/collide/dto/client", you 
can see my home directory string  "/home/ligen/" match the package_base string 
"gen/", this cause DtoGenerator generate wrong path of DtoClientImpls.java.

I provide a patch here. could you fix this defect? otherwise, I have to change 
my name :P.
