title: How to create a project using maven-archetype-plugin? What is artefactId etc?
body: <p>I am new to Maven and am using the <em>maven.apache.org</em> <a href="http://maven.apache.org/guides/getting-started/index.html#What_is_Maven">tutorial here</a> as an introduction.</p>
  
  <p>In the "<em>How do I make my first Maven project?</em>" section of the tutorial, it teaches us to generate a Maven archetype project by executing the following command:</p>
  
  <pre><code>mvn archetype:generate
  </code></pre>
  
  <p>After Maven downloaded  many artifacts, <strong>it suddenly stopped and asked the following question</strong> on the command line:</p>
  
  <pre><code>Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains): 149:
  </code></pre>
  
  <p>The Apache tutorial does not describe this prompt.</p>
  
  <p><strong>I have two questions:</strong></p>
  
  <p><strong>1.</strong> What is the question above asking for? How should it be answered such that the <code>mvn archetype:generate</code> process continues?</p>
  
  <p><strong>2.</strong> Conventionally, do people use <code>mvn archetype:generate</code> to create a Maven project?</p>
  
  <p><strong>--------------Update---------------------</strong></p>
  
  <p>With respect to my 1st question, I pressed "enter" without inputting any value and got the following output:</p>
  
  <pre><code>Choose version: 
  1: 1.0-alpha-1
  2: 1.0-alpha-2
  3: 1.0-alpha-3
  4: 1.0-alpha-4
  5: 1.0
  6: 1.1
  Choose a number: 6: 
  </code></pre>
  
  <p>What is that?</p>
  
  <p>I input "1" in above case, then I got the following things:</p>
  
  <pre><code>Define value for property 'package':  : :
  Define value for property 'groupId': : 
  Define value for property 'artifactId': :
  ...
  </code></pre>
  
  <p>How can I define them?</p>
