Let's talk about this project. It doesn't work: (at least not like it could or should)

Adding this to the parent pom does not fix it:

guru.springframework.sfgpetclinic.SfgPetClinicApplication

However, here is how you fix it:

Go to your parent POM file and change this section of code to this:

        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <skip>true</skip>
            </configuration>
        </plugin>

Then go to your pet-clinic-web POM file and add this section:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <skip>false</skip>
            </configuration>
        </plugin>
    </plugins>
</build>

Now you can run the mvn spring-boot:run command from anywhere inside of the project.
