title: Maven plugin version in pom (seemingly) ignored
body: <p>I'm noticing that Maven output is reporting plugin version numbers different than what I'm specifying in the pom file.</p>
  
  <p>For example, in my pom I specify the compiler plugin version of 3.1</p>
  
  <pre><code>&lt;plugin&gt;
    &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
    &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt;
    &lt;version&gt;3.1&lt;/version&gt;
  &lt;/plugin&gt;
  </code></pre>
  
  <p>But when Maven runs (package, install...whatever) it outputs that it used the version 2.3.2 for the compiler plugin</p>
  
  <pre><code>[INFO] --- maven-compiler-plugin:2.3.2:compile (default-compile)
  </code></pre>
  
  <p>Is there some global maven settings file that trumps local pom file configuration?</p>
