You should have a look at the optional task "depend". It does exatcly what
you want.
Just call it before "javac".
<target name="src" depends="prepare"
description="Compile all updated source files with dependencies.">
<depend closure="yes"
cache="${dep}"
srcdir="${src}"
destdir="${build}"
/>
<javac verbose="false"
srcdir="${src}"
destdir="${build}"
classpath="${classpath.compile}"
/>
</target>
