Visual Studio "Error: Undefined Interface" on header file then cause "QtRunWork" returned "false"

[setos95]

Hello,
I've been succesfully working on a project with Visual Studio and Qt VS tool extension for last months without any building issues.
After having accepted a small update on Qt Maintenance tool, my program can't build anymore.
I get an "Error: Undefined Interface" when proccess applies "moc ../{specific_file}.h" and generates a "QtRunWork has returned false".
This seems to be linked with the Qt Meta Object Compiler not finding the concerned header file... but I don't know what to do.
I've been trying to fix it for couple days now.

@setos95 Did you try a complete rebuild (delete build folder, run qmake/CMake, build)?

Of course, it did not work.
I wonder if this is caused by Qt VS tool extension's recent update for version 3.3.1.

I temporarily passed through the error by commenting "Q_INTERFACES()" macro in the concerned header and it runned.
However, this statement, had never caused issue before...

Hi,

Can you provide a minimal sample code that reproduces this behaviour ?

I have some problem.

Build log:

1>moc Header.h
1> E:\Projects\QtUndefinedInterface\Header.h(9): Error: Undefined interface
1>C:\Users<cut>\AppData\Local\QtMsBuild\qt_work.targets(138,5): error MSB4181: The "QtRunWork" task returned false but did not log an error.

@m0xf Please read the documentation: https://doc.qt.io/qt-6/qqmlparserstatus.html#details

"To use QQmlParserStatus, you must inherit both a QObject-derived class and QQmlParserStatus, and use the Q_INTERFACES() macro."
