Where does 'make sanity' look for the ANT version?

[Stuart Marks]

Hi Martijn!

One of my colleagues ran into this the other day. I don't know all the details 
and the solution but I have a clue that might help you move forward.

In make/common/shared/Sanity.gmk there are the lines,

> _ANT_VER:=$(shell $(ANT) -version 2>&1 )
> ANT_VER:=$(call GetVersion,"$(_ANT_VER)")

The GetVersion function (defined in Defs.gmk) extracts the version number from 
the shell output using a regexp. Unfortunately there seem to be circumstances 
-- not sure exactly what they are though -- when the shell output includes a 
*java* version number, either in the output or in a path. Clearly you're using 
Java 7 -- that is, JDK 1.7.0 -- and the GetVersion regexp is happily picking 
this up thinking it's the ant version number.

One path forward would be to investigate why "shell $(ANT) -version" is 
returning some unexpected output and is possibly not even running ant at all.

I'll forward this to my colleague to see whether he has anything to add.
