I am trying to run the gradle command. This has worked initially. However it has started failing after some time, as it is not able to start daemon. I am using Gradle 2.5 with IBM jdk 1.6 on Windows 7 Enterprise.
I have cleaned up the .gradle directory in my user home directory and restarted my system.
This is working fine on my friends machine with same versions. Please help.

Answer
Not certain about your scenario (and about IBM jdk) but whenever daemon, or in general any otherwise perfectly working build, suddenly stops working for me, I try two things.
gradle myTask --no-daemon
to run build without daemon in order to ensure if it is indeed a problem with daemon.gradle --stop
to kill any existing daemon and then try build again.
There is a word of caution about using daemons on Windows in the gradle docs:
It is also possible to destabilize the Daemon (and build environment in general) by running builds that do not release resources correctly. This is a particularly poignant problem when using Microsoft Windows as it is less forgiving of programs that fail to close files after reading or writing.
