This looks very interesting to solve and tycho is now capable of converting non OSGi Bundle to OSGi for maven dependency if we add ``` <pomDependencies>wrapAsBundle</pomDependencies> ``` .  Note : [https://wiki.eclipse.org/Tycho/Target_Platform#.22POM_dependencies_consider.22](https://wiki.eclipse.org/Tycho/Target_Platform#.22POM_dependencies_consider.22)  

but there is a catch .. If we use non OSGi dependency the "Bundle Symbolic name generated by tycho 2.x will be "**groupid.artifactId**"  where as the **p2-maven-plugin** (currently used for converting non OSGi to OSGi and hosting as a local p2 server convert Bundle Symbolic name to "**groupId**" (Note the missing artifactId

There are two solution i could think off and None of them are good at this point of time 

Solution 1 : Unify Core with application and remove p2-maven-plugin (+ remove releng /third-party) 
Solution 2 : Append Symbolic name with artifactId generated by p2-maven-plugin to match with the expected tycho compiler plugin (Not tested , but this might work) .
