Sencha SDK Tools does not Minified app-all.js

Question

I'm using Sencha SDK Tools 2 Beta 3 and ExtJS 4.0.7 in Windows 7 64bit.
After I build my project, the app-all.js file is not minified.

This is the .JSB3 file (that was generated by Sencha):

{
    "projectName": "Project Name",
    "licenseText": "Copyright(c) 2012 Company Name",
    "builds": [
        {
            "name": "All Classes",
            "target": "all-classes.js",
            "options": {
                "debug": true
            },
            "files": [
                // All Classes
            ]
        },
        {
            "name": "Application - Production",
            "target": "app-all.js",
            "compress": true,
            "files": [
                {
                    "path": "",
                    "name": "all-classes.js"
                },
                {
                    "path": "",
                    "name": "app.js"
                }
            ]
        }
    ],
    "resources": []
}

And Sencha result in command prompt: (Without Errors)

Answer 1

It was about an internal error.
I've replaced float with 'float' in my JS File and now it works.
