spark launch : find version

My environment is Windows 7, and scala 2.11.4 installed (works well), Java 1.8

I have tried spark-1.2.0-bin-hadoop2.4 and spark-1.2.1-bin-hadoop2.4 and each time I put

bin\spark-shell.cmd

I just got the error from Windows:

find: 'version': No such file or directory
else was unexpected at this time.

Is there anything I ignored here?

Thank you so much.

updated: (from spark-class2.cmd)

C:\Users\spark-1.2.1-bin-hadoop2.4>for /F "tokens=3" %i in ('java -version 2>&1 | find "version"') do set jversi on=%i
find: 'version': No such file or directory
else was unexpected at this time.

and if I try java -version, it seems working on java side

C:\Users\spark-1.2.1-bin-hadoop2.4>java -version
