I have basic application created with Cmd, with a single controller that has one view: 'ExtCalendar.view.Tree'. This view extends one of our classes ('Sch.panel.SchedulerTree') which is basically a TreePanel. Now when I'm trying to build the application I'm getting :

[TRACE] processing graph for class : ExtCalendar.view.Tree
[ERROR] Failed to resolve dependency Sch.panel.SchedulerTree for file ExtCalendar.view.Tree
[DEBUG] removing tempdir /Library/WebServer/Documents/Bar/sencha-compile-temp-dir
[ERROR] BUILD FAILEDcom.sencha.exceptions.ExNotFound: Unknown definition for dependency : Sch.panel.SchedulerTree
even though the application itself is running without any problems. My app.json looks as follows :

Code:
{
    "name": "ExtCalendar",
    "js": [
        {
            "path": "ext/ext-all.js"
        },
        {
            "path": "../../ExtScheduler2.x/sch-all-debug.js"
        },
        {
            "path": "app/app.js",
            "update": "delta"
        }
    ],
    "css": [
        {
            "path": "resources/css/default/app.css",
            "update": "delta"
        },
        {
            "path": "../../ExtScheduler2.x/resources/css/sch-all.css"
        }
    ],
    "appCache": {
        "cache": [
            "index.html"
        ],
        "network": [
            "*"
        ],
        "fallback": []
    },
    "extras": [
        "resources/images",
        "resources/icons",
        "resources/loading"
    ],
    "archivePath": "archive",
    "buildPaths": {
        "testing": "build/testing",
        "production": "build/production",
        "package": "build/package",
        "native": "build/native"
    },
    "buildOptions": {
        "product": "ext",
        "minVersion": 3,
        "debug": true,
        "logger": true
    }
}
and finally app.js :

Code:
Ext.Loader.setConfig({
    enabled: true,
    disableCaching: false
});


Ext.application({  
    name: 'ExtCalendar',
    controllers: ["TreeCalendar"],
    autoCreateViewport: true
});
Should the required classes be included somewhere or is there a different approach for this ?
