title: <g:resource> <r:layoutResources> unknown tags in grails project ?Also features of bootstrap are not rendered in .gsp file. What's the solution?
body: <p>I have installed twitter bootstrap plugin in <code>buildConfig.groovy</code> file, but none of the bootstrap features seem to be rendered in my .gsp files. Also, when I try to use tags like <code>&lt;g:render&gt;</code>, <code>&lt;g:each&gt;</code> , <code>&lt;g:resource&gt;</code> anything, it shows me an error saying unknown tag.</p>
  
  <pre><code>&lt;!DOCTYPE&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;Perkin Elmer Support&lt;/title&gt;
      &lt;meta charset="utf-8"&gt;
      &lt;meta name="layout" content="main"/&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1.0"&gt;
      &lt;meta name="description" content=""&gt;
      &lt;meta name="author" content=""&gt;
      &lt;g:resource dir="css" file="main.css" /&gt;
  &lt;!-- appears as unknown tag and also none of &lt;g:..&gt; tags work !--&gt;
  
      &lt;asset:stylesheet src="../stylesheets/bootstrap-theme.css"/&gt;
      &lt;asset:stylesheet src="../stylesheets/bootstrap.css"/&gt;
      &lt;asset:stylesheet src="../stylesheets/bootstrap.min.css"/&gt;
      &lt;asset:stylesheet src="../stylesheets/bootstrap-theme.min.css"/&gt;
      &lt;asset:stylesheet src="../stylesheets/application.css"/&gt;
      &lt;asset:javascript src="../javascripts/application.js"/&gt;
      &lt;asset:javascript src="../javascripts/bootstrap.js"/&gt;
      &lt;asset:javascript src="../javascripts/bootstrap.min.js"/&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>In buildConfig.groovy also i have installed the plugin.</p>
  
  <pre><code>runtime ":hibernate4:4.3.5.3" // or ":hibernate:3.6.10.15"
  runtime ":database-migration:1.4.0"
  runtime ":jquery:1.11.1"
  runtime ':twitter-bootstrap:3.1.1.3'
  </code></pre>
  
  <p>How do I link to bootstrap files in my gsp page ?
  And I can't use any of <code>&lt;g:resource&gt;</code> <code>&lt;g:render&gt;</code> , <code>&lt;g:..&gt;</code> tags inside my .gsp file ?</p>
