title: grails plugin repositories
body: <p>By default, the following repositories are configured in <code>BuildConfig.groovy</code></p>
  
  <pre><code>repositories {
      grailsPlugins()
      grailsHome()    // look inside the grails installation
      grailsCentral()
  }
  </code></pre>
  
  <p>I understand that the <code>grailsHome()</code> repository corresponds to the JARs that are available within the local Grails installation, and I guess <code>grailsPlugins()</code> corresponds to the repository where <a href="http://grails.org/plugin/category/all" rel="noreferrer">released Grails plugins are stored</a>.</p>
  
  <p>Am I right about these two, and if so, what is <code>grailsCentral()</code>?</p>
