Cannot launch application through qtcreator

Looks like something wrong with the command which gets built by /usr/share/qtcreator/ubuntu/scripts/qtc_device_run_app

Using the trunk of clock it generated

ssh -i /home/alan/.ssh/ubuntudevice_04c770facfe7991f_id_rsa -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -p2222 phablet@127.0.0.1 "bash -ic 'qmlscene /home/phablet/dev_tmp/ubuntu-clock-app/ubuntu-clock-app.qml --desktop_file_hint=/home/phablet/.local/share/applications/ubuntu-clock-app.desktop'"

This is the result:-

alan@deep-thought:~$ ssh -i /home/alan/.ssh/ubuntudevice_04c770facfe7991f_id_rsa -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -p2222 phablet@127.0.0.1 "bash -ic 'qmlscene /home/phablet/dev_tmp/ubuntu-clock-app/ubuntu-clock-app.qml --desktop_file_hint=/home/phablet/.local/share/applications/ubuntu-clock-app.desktop'"

A fix is to add missing " -platform ubuntu" to /usr/share/qtcreator/ubuntu/scripts/qtc_device_run_app

This has been fixed for the upcoming 2.8 release.

This bug was fixed in the package qtcreator-plugin-ubuntu - 2.7.2-0ubuntu3
