Try something like:

<target name="publish">
      <ivy:publish resolver="pubRepo">
          <artifacts pattern="dist/[artifact]-[revision].[ext]"/>
      </ivy:publish>
</target>

This will take all the defaults from the ivy settings you are using. I assume that your ant 'basedir' ===
workspace\MyProject\
