I just downloaded this project:

https://github.com/oktadeveloper/okta-spring-boot-2-angular-5-example

explained on this tutorial:

https://developer.okta.com/blog/2017/12/04/basic-crud-angular-and-spring-boot

But when I try to run the server with the recommended command:

./mvnw spring-boot:run

I get the following output:

As you can see, there is one line that says:

The Tomcat connector configured to listen on port 8080 failed to start.

Any idea on how to make the server work?

Thanks!

It says "BindException: Address already in use: bind", you must already be running some application under port 8080. Try to terminate that server and start again, or use a different port for this application, like 8081. If you can't check which app is using port 8080 already, use the following command

netstat -anob

You can now check and kill the application through task manager, assuming you're on windows.

It says "BindException: Address already in use. Check below command to see if port is in use: lsof -i:8080 And then kill the process using: Kill -9

Alternatively you can use another port.
