Google Closure Compiler

apt-get install sun-java6-jdk sun-java6-plugin update-java-alternatives -s java-6-sun

Once either one is done, run the

sudo update-java-alternatives -s java-6-sun

command and finally add the line “/usr/lib/jvm/java-6-sun” to the top of the /etc/jvm file

(

gksudo gedit /etc/jvm

). Save and exit. To test your Java(TM) setup in the terminal type:-

mkdir /usr/share/closure-compiler cd /usr/share/closure-compiler wget http://closure-compiler.googlecode.com/files/compiler-latest.zip . unzip compiler-latest.zip src/Blogger/BlogBundle/Resources/views/Default/layout.html.twig {% javascripts '@BloggerBlogBundle/Resources/public/js/*' output='js/compressed.js' filter='closure' %}
