Visual Studio Code setup for Java WebApp Project without main method

I am looking to setup this project ( https://github.com/afawcett/githubsfdeploy) on my local machine. I'm not too familiar with Java but I feel I've been able to do enough (MAVEN, JAVA environment downloads and system variable settings) to get my windows machine up and running along with Visual Studio Code. I was able to get the spring boot project up and running in visual studio code without any issues so I want to believe I have all the required pieces (https://code.visualstudio.com/docs/java/java-spring-boot).

The spring-boot project has a main method and the one I'm trying to recreate doesn't. I am receiving the error when debugging the githubsfdeploy project that a "main" method could not be found. I've been researching other ways to run a java project without using the main method but haven't recognized the missing piece yet. Would love some direction on what I may not be taking into account. Thanks!

This is a Maven project which based on the concept of a project object model (POM). So first, you should download Maven and Tomcat locally.

My machine: win10, vscode1.49.0, JDK11

VS Code Extension installed: Java Extension Pack, Tomcat for java

and i download: apache-maven-3.6.3-bin.zip and Tomcat9.0.38 and extract them

1. Add maven to Environment Variables:

   ---\apache-maven-3.6.3-bin\apache-maven-3.6.3\bin

2. Open the project in VS Code, add the following code in User settings.json:

   "maven.executable.path": "---\apache-maven-3.6.3-bin\apache-maven-3.6.3\bin\mvn",

3. Follow the picture steps:

4. Add the tomcat server and run the .war on tomcat, here is a gif tutorial: work with tomcat

Finally, you will observe this result:

When you can run it successfully, debugging is achievable: right click the tomcat server and choose debug war packages:
