Question

Answer 1

I didn't need to set up remote debugging in order to get this working, I used Maven.

1. Ensure you have the Maven plugin installed into Eclipse.
2. Click Run > Run Configurations > Maven Build > new launch configuration:
   • Base directory: browse to the root of your project
   • Goals: spring-boot::run.
3. Click Apply then click Run.

NB. If your IDE has problems finding your project's source code when doing line-by-line debugging, take a look at this SO answer to find out how to manually attach your source code to the debug application.
