The current skeleton is being worked on. Because it was part of ESH but hasn’t been moved to openHAB-core yet I’ve created a pull request for it. But as there is also work done on moving to an pure maven build system the idea is to also change the skeleton to generate these new maven supporting build files. My idea is to after getting the basics included again to extend the skeleton and add more (example) code. Maybe a discovery example should also be part of this.
There was recently also a different topic about generating code to also help developers, see
