By the way, how did you install your JDK? I installed JDK = under windows,=C2=A0and then=C2=A0in Cygwin, I point to that JDK. If you bu= ild and install JDK under Cygwin, the file path with "\\" might n= ot work since Cygwin (Linux) uses "/" as separator.

I k= ind of remember I hit similar issue when building hadoop 2.4. I changed the= source code to use the full path of protoc.exe.=C2=A0It is in hadoop-maven= -plugins\src\main\java\org\apache\hadoop\maven\plugin\protoc\ProtocMojo.jav= a:
=C2=A0
protocCommand =3D "C:\\cygwin64\\usr\\local\\bin= \\protoc.exe";
=C2=A0
Then the build worked for me= .
