Could not exec java with Spring+Maven exit code 1

Question

I am new to Spring/Maven, and am following this tutorial: Serving Web Content with Spring MVC.

Everytime I run mvn spring-boot:run, I get this error:

Answer 1

I made the following changes to make mvn clean spring-boot:run work:

• Move pom.xml to the root directory, which makes the directory hierarchy to be:

Directory hierarchy:

.
├── pom.xml
└── src
    └── main
        ├── java
        │   └── hello
        │       ├── Application.java
        │       └── GreetingController.java
        └── resources
            └── templates
                └── greeting.html

• Commented out the extensions in the following part:

Commented out part:

        org.springframework.boot
        spring-boot-starter-web
        
        
            
                
                
            
            
                
                
            
            
                
                
            
        
    

It seems you meant to exclude those dependencies. mvn clean spring-boot:run will just exit successfully if the embed tomcat is excluded, but I think this is the correct behave because there's no container to deploy the application. Anyway, you can try it out and make changes according your requirements.
