Not sure why build tries to read settings.gradle of the parent project.
Putting our own empty one for now else the inner gradle (Qt one) will fail.
 

Error: "Project directory '_{/QtPluginTest/app/build/qt_generated/PluginTest/android-build' is not part of the build defined by settings file '}/QtPluginTest/settings.gradle'. If this is an unrelated build, it must have its own settings file."
