I’m porting a plasmoid5 to plasmoid6. I have this in main.qml:

    Plasma5Support.DataSource {
        id: localTime
        engine: "time"
        connectedSources: ["Local"]
        interval: updateInterval
    }

according to documentation it should work but I get error:

…/contents/ui/main.qml:30:5: Plasma5Support.DataSource – Plasma5Support is neither a type nor a namespace.

I have seached Google and there is no such an error reported previously.
