> If <outputFileNameMapping> maps two or more artifacts into the same name, it needs to be reported as an error.
> Maven currently just takes the last one without reporting anything, and as a result I didn't notice that my assembly descriptor had a problem until I debug the plugin source code.
> This problem is particularly made worse by a broken jar-with-dependencies example in [the documentation|http://maven.apache.org/plugins/maven-assembly-plugin/descriptor-refs.html], which says:
> {noformat}
>   <dependencySets>
>     <dependencySet>
>       <outputDirectory></outputDirectory>
>       <outputFileNameMapping></outputFileNameMapping>
>       <unpack>true</unpack>
>       <scope>runtime</scope>
>     </dependencySet>
>   </dependencySets>
> {noformat}
> ... which maps every dependency to ""
