QML tutorial does not run on Utopic desktop

In the project:

[Desktop Entry]
Name=CurrencyConverter
Exec=qmlscene $@ main.qml
Icon=CurrencyConverter.png
Terminal=false
Type=Application
X-Ubuntu-Touch=true

However, the main QML file in the project is "Main.qml" instead of "main.qml". The app does not run at all in the SDK.

The app does not run in the phone as well:

rsync: failed to open exclude file /home/liuxg/qml/ubuntu-sdk-tutorials/getting-started/CurrencyConverter/.excludes: No such file or directory (2)
rsync error: error in file IO (code 11) at exclude.c(1179) [client=3.1.1]

Error while building/deploying project CurrencyConverter (kit: UbuntuSDK for armhf (GCC ubuntu-sdk-14.10-utopic))
