title: Grails Asset Pipeline - minifyJs set to true not working
body: <p>I used grails asset pipeline plugin to minify my application (I don't have any problem when running grails run-app) the problem arises when I'm going to generate a war file to deploy into tomcat server.</p>
  
  <p>Currently using <strong>':asset-pipeline:1.9.9'</strong></p>
  
  <p>currently My <strong>Config.groovy</strong> has this setup</p>
  
  <pre><code>grails.assets.minifyJs = true
  grails.assets.minifyCss = true
  grails.assets.bundle = true
  </code></pre>
  
  <p>The Particular problem here is when I'm going to set <strong>minifyJs = true</strong></p>
  
  <p>when I'm going to set <strong>minifyJs = false</strong> there's no error but my war file are not going to work when deployed to tomcat server.</p>
