title: How to run a new Maven-based “quickstart” app in IntelliJ?
body: <p>I used the Maven archetype <a href="https://maven.apache.org/archetypes/maven-archetype-quickstart/" rel="nofollow noreferrer"><code>maven-archetype-quickstart</code></a> at the command-line to generate a new project. I imported that project into IntelliJ 2017.1. </p>
  
  <ul>
  <li>How do I run the app? </li>
  <li>How to debug the app? </li>
  </ul>
  
  <p>The green triangle button to run the app is disabled. </p>
  
  <p>I opened the panel listing Maven lifecycle and plugins. But I do not see any action for running the app.</p>
