qml module is not installed error

Fei Su

I have a qml module with plugin, the qml files used to put in local files. Now we move the qml files into resource, and then I get the module not installed error.
I do add resource into app .pro file.
The original file structure is:

The part of the new resource file is:

<RCC>
    <qresource prefix="/qml/components">
        <file>private/qmldir</file>
        <file>private/AlphaInput/AlphaInputBase.qml</file>
        <file>private/AlphaInput/AlphaInput.qml</file>
        <file>private/BorderImageMask.qml</file>
        <file>private/BorderImageScaled.qml</file>
        <file>private/ButtonGraphics/ButtonGraphics.qml</file>
        <file>private/ComboBox/ListDelegate.qml</file>
        <file>private/ComboBox/List.qml</file>
        <file>private/ComboCheckBox/CheckBox.qml</file>
        <file>private/ComboCheckBox/CheckListDelegate.qml</file>
        <file>private/ComboCheckBox/CheckList.qml</file>
        <file>private/ComponentBase.qml</file>ource>
    </qresource>
</RCC>

The error message:
