Steps to reproduce

environment

• Windows 10
• git bash
• Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-18T03:33:14+09:00)
• Java(TM) SE Runtime Environment (build 1.8.0_161-b12)

patch
Changed samples/server/petstore/jaxrs-spec/jaxrs-spec/pom.xml to add the generated sources into its compilation. (fujigon@69d51fd#diff-4b89ff23dee396d29fbaa7412736b5bf)

And I kick

cd samples/server/petstore/jaxrs-spec
mvn test

then, I get compile error https://gist.github.com/fujigon/f5c8e591548e0e8ec30bc019be73ad9d.

Suggest a fix/enhancement

Currently, the whole project is buildable because it doesn't add sub-projects jaxrs-spec, jaxrs-spec-interface, and jaxrs-spec-interface-response into the root project.

I think these sub-projects should be integrated to the root project with profile as the other sample projects are, so that CI confirms that the sub-projects are buildable. (like fujigon@69d51fd#diff-600376dffeb79835ede4a0b285078036)
And then, we need to modify the jaxrs-spec language mustache template so that the generated code is compilable.

@fujigon thanks for reporting the issue. You're right and please file a PR with the patch to fix the pom.xml to start with. We'll then work together to fix the remaining issues.
