How can i create provider hosted app package for SharePoint 2013 App Catalog by using MSBuild

I have created a provider hosted app for my SharePoint 2013 online which created using visual studio 2012. Now I want to create an app package of it using MSBuild or any other way also pass the ClientId and Secret key in it. (like in visual studio by right click on project and Publish it).

Please let me know if you have any solution.

Thanks and Regards, Rushil
