Sencha CMD concatenate files - how to turn off YUI compression?

[Qarea]

Trying to make one big js file from my app

sencha compile -classpath=extjs/src,app concat app-all.js 

but getting lots of "YUI Compressor Error" - like

[ [2000] : YUI Compressor Error <> missing name after . operator =>     this.goto = function (params) { 

- looks like problem is in my custion function called goto

 [ [2000] : YUI Compressor Error <> invalid property id =>                     float: 'right', ] 

- problem is in attribute called "float"

I do not want fix this errors, and I do not need compress js file at all - I just need concat all my js files into one working file, like ext-all.js , how can I do it?
Didnt found option how to disable YUI, tried use

sencha compile -classpath=extjs/src,app concat -closure app-all.js 

- but still getting YUI errors

Was the app generated by Cmd?

No

It seems that YUI compressor takes float and goto as reserved words. Use another names.

This names are used in lots of files lots of times, I cant spend much time to fix such errors and possible lots other errors - I tried to compile different set of files and get another not-real-errors. How can I disable YUI compression, or use another compression tool like closure compiler? I've posted above code where trying to use -closure, but getting same yui errors, what is correct syntax or what is wrong?
