  <p>I'm going to create a project with Maven using a <code>maven-archetype-webapp</code> archetype. Why can't I do it? I've just started learning Maven so the error doesn't tells me anything:</p>
  
  <pre><code>[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-
  plugin:2.3:create (default-cli) on project standalone-pom: Unable to 
  parse configuration of mojo org.apache.maven.plugins:maven-archetype
  plugin:2.3:create for parameter #: Abstract class or interface
  'org.apache.maven.artifact.repository.ArtifactRepository' cannot be 
  instantiated: org.apache.maven.artifact.repository.ArtifactRepository.
  &lt;init&gt;() -&gt; [Help 1]
  </code></pre>
  
  <p>I don't want to have any other archetypes or a default archetype.</p>
