Could you suggest how to generate build config fields with String type from gradle?

Why not env. vars. And System.getenv(key)? They're also more docker friendly, if needed...

Agree, environment variables probably the easiest solution.
One more option, if you use application gradle plugin to run your server, you can pass this property as argument to run task
