Unable to deploy tomcat server with Spring boot

Question

I have been trying to deploy my tomcat server for a couple of days using spring boot but I cannot for the life of me figure out what I'm doing wrong with my configuration. I have looked at a couple of suggestions online but I still cannot figure out what I'm doing wrong. I have a feeling it could be something little but at this point, I don't think I'm getting anywhere with the issue

I have my maven configuration file and am trying to leverage the apache tomcat maven plugin in deploying my server.

http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

  <groupId>com.blah.maven</groupId> <artifactId>blah</artifactId> <version>1.0-SNAPSHOT</version> <packaging>war</packaging> <name>foo</name> <properties> <springframework.boot.version>1.5.9.RELEASE</springframework.boot.version> </properties> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <!-- <scope>provided</scope> --> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <url>http://localhost:8080/manager/text</url> <path>/blah</path> </configuration> </plugin> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>${springframework.boot.version}</version> </plugin> </plugins> </build> </project> 

And in my project I have an Application class

    package foo;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.boot.builder.SpringApplicationBuilder;
    import org.springframework.boot.web.support.SpringBootServletInitializer;
    import org.springframework.web.WebApplicationInitializer;

    @SpringBootApplication
    public class Application extends SpringBootServletInitializer implements WebApplicationInitializer {

        public static void main(String [] args){
            SpringApplication.run(Application.class, args);
        }

        @Override
        protected SpringApplicationBuilder configure(SpringApplicationBuilder application){
            return application.sources(Application.class);
        }
    }

Here's a screen shot of my stack

Answer 1

Probably you need to configure the Tomcat Authentication.

Follow this example from https://www.mkyong.com/maven/how-to-deploy-maven-based-war-file-to-tomcat

And at Maven side:

Answer 2

That was a total brain fart on my part. I was trying to deploy the application (mvn tomcat: deploy) without actually having the an instance of tomcat running. What I really wanted to do was create and run an instance of tomcat in my maven project(mvn tomcat: run).

Could not believe I spent quite a lot of time on something so trivial. Oh well, live and learn.
