[Error] Package import requires a version number

Got a strange error when compiling a project. It still works, no compile-time or run-time error. Just a default KAppTemplate.

Main.qml

import QtQuick | package import requires a version number
import QtQuick.Controls as QQC2 | package import requires a version number
import QtQuick.Layouts | package import requires a version number
import org.kde.kirigami as Kirigami | package import requires a version number
import org.kde.helloworld | package import requires a version number

Discover, Marknote and other apps don’t use these version numbers. Ideally, what should I do? Can I suppress it at least?

KDevelop version 5.14.240502 (24.05.2)
