You have to expand your pattern to include the type, so that each artifact gets it's own local file:

<ivy:retrieve pattern="lib/[conf]/[artifact]-[type]-[revision].[ext]" />

Or if you don't need the sources and the javadoc you can change the dependency to:

<ivy-module version="2.0">
    <info organisation="org.apache" module="hello-ivy"/>
    <dependencies>
        <dependency org="commons-lang" name="commons-lang" rev="2.1" conf="default->master"/>
    </dependencies>
</ivy-module>

Which will only retrieve the master-conf(jar) of the dependency.
