OpenJDK rebuilding on windows takes a long time

   Building one line change in OpenJDK on my Windows takes about from 4 
to 7 minutes.

I tried to install the ccache-3.1.9 but build process fails with error:
-------------------------------------------------
LINK : fatal error LNK1181: cannot open input file 
'c:/Sun/OpenJDK/jdk8-awt/build/windows-x86-normal-server-release/jdk/objs/libverify/check_code.obj'

Could not start process!  Failed with error 2: ?? ??????? ?????

-------------------------------------------------

  7 minutes is too long for the small change rebuilding. The previous 
systems makes it faster.
  Is it possible to use the ccache on windows or make the rebuilding 
process faster?

Thanks,
Alexandr.
