mainClassName = "package.ApplicationRunner"

Run the application from the IDE or command line using the command gradle build run

Now the IDE can connect to the remote JVM (on port 7000) where the spring boot application runs. It also supports hot deployment of static files.

or even you can run the main class from intelliJ if the dependencies are properly managed in the IDE. The main class is the class that contains the main method which will call SpringApplication.run("classpath:/applicationContext.xml", args);
