I compile a project successfully. But when I press on Run button I get an error

Errors occurred during the build.
Errors running builder 'CDT Core Builder' on project 'door_beacon'.
java.lang.NullPointerException

How do I configure the project to flash on my dev board?

IIRC this vid helped me to start with eclipse

Now I think vs code is easier and better to use, but you maybe like or need to use eclipse, so good luck.
