Yes, I want to build with Eclipse MicroProfile. Then, do I have to do everything from scratch? Are there tools out there to make my life easier to code MicroProfile-based applications? We will review what's out there, talk about what's coming, and show them in action. This was a talk delivered as part of J4K.io 2020.
