After updating Qt to 6.6.0-beta1, kjobwidgets (the Qt6 version from git master branch) no longer builds.

[1/28] cd /home/bero/repos/packaging-tools/kf6-kjobwidgets/BUILD/kjobwidgets-master/build/src && /usr/lib64/qt6/./libexec/moc @/home/bero/repos/packaging-tools/kf6-kjobwidgets/BUILD/kjobwidgets-master/build/src/moc_jobviewiface.cpp_parameters

ninja: build stopped: subcommand failed.

jobviewiface.h is generated by qdbusxml2cpp.

The problematic line 39 is

Q_NOREPLY inline void clearDescriptionField(uint number)

The problem seems to be the use of Q_NOREPLY. Manually removing that from this line (and various other lines like it) fixes the build.

Attaching the XML file moc_jobviewiface.cpp is generated from.
