Answer 1

I believe you’re trying to follow the DIO Bootcamp Inter project. Probably during the processing of the installation gave some kind of problem that is not able to identify, here I was able to solve as follows:

In the root directory of your project run the command (Linux):

$ ./mvn clean install

If you imported your project with Intellij for example, try:

$ ./mvnw clean install

Finally run the run again:

$ ./mvn spring-boot:run

or

$ ./mvnw spring-boot:run

Please give an upvote if this answer was helpful to you. Good luck!
