Could it be something in my config that I need to change to make it work?
application.properties

spring.datasource.username=root
spring.datasource.password=root

public class RestApiSpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(RestApiSpringbootApplication.class, args);
}
}
Entity
#Entity
#Table(name = "customer")
public class Customer implements Serializable {
// getters and setters
}
Repo
public interface CustomerRepository extends CrudRepository<Customer, Long> {
List<Customer> findByLastName(String lastName);
}
Update
I just notice when I mvn clean install I also get the following errors. But I checked my build path both JRE[JavaSE-1.8] and maven dependencies are build path...

As discussed in the comments, your error says, java.lang.NoClassDefFoundError: javassist/bytecode/ClassFile.
As you were migrating from spring boot version 1.5.9 RELEASE to 2.0.1 RELEASE, there might be some conflict in the javassist jar (3.20.0-GA vs 3.22.0-GA).
So you can clean your maven repo (delete the localRepository) and run your command once again.
