title: Can't find Flyway maven plugin
body: <p>In my pom.xml, I have:</p>
  
  <pre><code> &lt;plugin&gt;
      &lt;groupId&gt;org.flywaydb&lt;/groupId&gt;
      &lt;artifactId&gt;flyway-maven-plugin&lt;/artifactId&gt;
      &lt;version&gt;3.1&lt;/version&gt;
      &lt;configuration&gt;&lt;/configuration&gt;
   &lt;/plugin&gt;
  </code></pre>
  
  <p>to test the plugin, I'm doing:</p>
  
  <pre><code>mvn flyway:migrate
  </code></pre>
  
  <p>But I get an error:</p>
  
  <pre><code>[ERROR] No plugin found for prefix 'flyway' in the current project and in the pl
  ugin groups [org.wildfly.plugins, org.flywaydb.plugins, org.apache.maven.plugins
  , org.codehaus.mojo] available from the repositories [local (C:\Users\me\.
  m2\repository), central (https://repo.maven.apache.org/maven2)] -&gt; [Help 1]
  </code></pre>
  
  <p>What am I missing from my pom? the flyway plugin IS in central.</p>
