build.sh

#!/usr/sh -e

#clone our private github repo with Xamarin project
git clone git@github.com/our_xamarin_project.git
cd our_xamarin_project
#update homebrew 
brew update
#install Xamarin.Studio, Xamarin.iOS, Xamarin.Android, Mono
brew cask install xamarin-mdk xamarin-ios xamarin-studio xamarin-android
#install nuget dependencies
nuget install MoviesPrototype.iOS/packages.config
# The license file is stored in the repo, we need to copy it to the ~/Library/MonoTouch as suggested here https://developer.xamarin.com/guides/ios/getting_started/installation/offline_activation/
cp Licenses/iOS/License.trial ~/Library/MonoTouch
#Now log into the Xamarin developer@connect.com account
~/Applications/Xamarin\ Studio.app/Contents/MacOS/mdtool account login -u "$XAMARIN_USER" -p "$XAMARIN_PASSWORD"
#And finally build the project
~/Applications/Xamarin\ Studio.app/Contents/MacOS/mdtool build MoviesPrototype.iOS/MoviesPrototype.iOS.csproj

There are two errors I'm seeing:
First

Checking licenses...
Sync error: You have reached the maximum number of activations.

Second

Xamarin Studio Build Tool
�=$<50>error: The Starter Edition of Xamarin.iOS does not support building outside of Xamarin Studio. Please go to https://store.xamarin.com to upgrade to the Business Edition.

Please let me know what i'm doing wrong?
