Java heap space

[dluhhbiu]

I use closure-compiler for js compressor.
My config:

  config.assets.js_compressor = :closure
  require 'closure-compiler'
  config.assets.js_compressor = Closure::Compiler.new(
    compilation_level: 'ADVANCED_OPTIMIZATIONS',
    language_in: 'ECMASCRIPT6',
    language_out: 'ES5'
  )

And my deploy failed:

rake aborted!

dcodeIO/ClosureCompiler.js#19
I know the problem, but I do not know how and where to add these parameters
