[Fiware-middleware] Links and template-project to start with gradle

[Marti Christof (mach)]

Hi Dimitri

I will look into this tonight. I think it has to to with a missing sourceSet definition for antlr4. Normally the IDE plugins take all the sourceSets and add source locations in the IDE config files.

At the moment you will have to add the antrl4 output location "build/generated-src" manually in the IDE.
