Developer Guide: Server Application
Right click on the BugQueryServerSide project, and select Run As, then Maven build....
In the Edit Configuration window, put spring-boot:run as the goal, and click Run.
The project will build and run in http://localhost:8080/ (unless a different port was requested in BugQueryServerSide/src/main/resources/application.properties, or the port was already in use).
To connect the local server to the MySQL database, you'll need to setup a tunnel into the online server (see Developer Guide: Server), and put its address in the application.properties file (see Setting up a connection to the database in our database guide).
