Unable to add jar file to .ivy cache manually

I am trying to manually add lucene jar file to my local ivy repository. I have other apache jars so under the existing folder .ivy2\cache\apache.org\ I've created a folder called lucene and inside it a folder called jars. I then placed the jar named lucene-3.0.3.jar in the jars folder. Next step I've created the following ivy-3.0.3.xml in the lucene folder:

<?xml version="1.0" encoding="UTF-8"?>

<ivy-module version="1.0">
    <info organisation="apache.org" module="lucene" revision="3.0.3" status="release" publication="20090416105712">
   </info>
   <publications>
      <artifact name="lucene-3.0.3" type="jar" ext="jar"/>
   </publications>
</ivy-module>

I then try to reference it from a project like that:

<dependency org="apache.org" name="lucene" rev="3.0.3"/>

But I get an error: "unresolved dependency: apache.org#lucene;3.0.3: not found"

I am able to find other dependencies from my .ivy2 cache folders, just this one that I've created manually is giving problems.

Anything I have missed?
