enums, qml, qmake and rcc

felsi

Hallo!

I created a simple test project:
TestProject_Enums_Compat.pro

QT += quick

SOURCES += \
        main.cpp

resources.files = main.qml
resources.prefix = /$${TARGET}
RESOURCES += resources

# Default rules for deployment.
qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

HEADERS += \
    definitions.h

Then i add an enum in a namespace:
definitions.h

#include <QObject>

namespace SETTINGS
{
    Q_NAMESPACE

    enum EnumTest {
        VALUE_0,
        //VALUE_X,
        VALUE_1
    };

    Q_ENUM_NS(EnumTest)
}

I register it and start a qml app:
main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>

#include "definitions.h"

int main(int argc, char *argv[])
{
    qmlRegisterUncreatableMetaObject(SETTINGS::staticMetaObject, "Settings", 1, 0, "SETTINGS", QStringLiteral("SETTINGS should not be created in QML"));

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/TestProject_Enums_Compat/main.qml"));
    QObject::connect(
        &engine,
        &QQmlApplicationEngine::objectCreated,
        &app,
        [url](QObject *obj, const QUrl &objUrl) {
            if (!obj && url == objUrl)
                QCoreApplication::exit(-1);
        },
        Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

My qml code is also very simple:
main.qml

import QtQuick
import Settings 1.0

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Enum Test Project")

    Component.onCompleted: console.debug("IS: " + value_1 + "  SHOULD BE: " + SETTINGS.VALUE_1)

    property int value_1: SETTINGS.VALUE_1
}

And here the bug:

When i change the enum, e.g. adding VALUE_X, i get the following output:
IS: 1 SHOULD BE: 2

So, i made a clean rebuild: same output
I deleted the build folder: same output
I reset all project configurations: same output
I reset the qml code model: same output
I closed the project, closed QtCreator, deleted the build folder, i even rebooted my computer: same output

Note, i still use qmake.
It works as expected with cmake.
It works when i build the project with another Qt version.
It also works when i activate the Qt-Quick-Compiler.
And it works, when i overwrite main.qml (without making any changes).
But i still get the same output, when i copy all files to another folder!
You can see the complete content of all involved files above...

So how can that be?
Does the rcc use some sort of cache?
