Uncheck "Install automatically" and an ANT_HOME field should appear. Try setting the installation there if you have not tried it already.
actually its working well for few other projects in the master for this one only giving that problem...
im running this project in the slave ....so tell me if any confiruration are required there???

added a comment - im waiting for your solution!!!!!!!!!! You can set the location of Ant Installation in your slave in the slave's configuration page. If you scroll all the way down and check "Tool Locations" you will see the option to add an Ant installation location for your slave.
from command line it is running fine only and but when i try with jenkins its giving the error ....
and its not a problen with Ant-Pluggin
