Sencha SDK Tools does not Minified app-all.js - extjs4

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.
