Eclipse warnings using the iajc ant task

Question

We are currently using the Aspect J ant compiler iajc to compile our code.
Now we want to get the Eclipse warnings when compiling with ant but we don't want to change away from using the iajc ant task.
Is there a possible way to achieve this?

Currently our compile iajc task looks like this:

<iajc outJar="${dist}/${dist.jar}" source="1.6" sourceRootCopyFilter="**/*.java,**/*.aj" debug="true" nowarn="false" warn="${iajc.warn}" log="${tmp}/compile.log">
  <sourceroots>
    <pathelement location="${module-src}"/>
  </sourceroots>
  <classpath refid="master-classpath" />
  <classpath refid="module-classpath" />
</iajc>
