How to Pass parameters for a Ant script , which is invoked via shell script?

Do you mean assigning value to a property from command line? If so, try

-DpropertyName=itsValue

For example,

<project>    <target name="hi">        <property name="person" value="world"/>        <echo message="Hello ${person}"/>    </target></project>

and then

ant -Dperson="MerryPrankster" hi

yields

 [echo] Hello MerryPrankster
