Getting Execution failed for task ':bootRun'

The stack trace keeps pointing to the SpringApplication.run(AppConfig.class, args); line in AppConfig.java. I have no idea how to fix this, my code looks identical to the video, its just running with modern updates.

It seems as though the port 8080 is already being used.

Try adding a new file to src/main/resources called application.properties with the following code:

server.port = 1234

Set 1234 to the desired port number, or set to 0 for a random port number.
