    </ant>
</target>

I want to build ant target compile-junit only if some of the jar doesnt exist in perticulary directory, how can i do it? ie compile-junit target inside buidljunit should run only when there is no jar file exist in the directory project/jarlocation/dcs.

Slight variation to the question I commented as similar. To run when it doesn't exist replace 'if' with 'unless':

<target name="check-abc">
    <available file="abc.txt" property="abc.present"/>
</target>

<target name="do-unless-abc" depends="check-abc" unless="abc.present">
    ...
</target>
