On executing ant -verbose run command I am getting below error.I request humbly kindly help me, I have googled everything but found nothing. I am stuck very badly in this and trying for last 4 days. :(

java.io.IOException: Cannot run program "C:\Program Files\Java\jre1.8.0_31\bin\java.exe": Create Process error=206, The Filename or extension is too long.

Answer 1

After hours of en-devour, I am able to solve the issue. Please remove unnecessary jar files from Classpath and try. It worked for me. Cheers..:)
