The Cordva version used for building AppBuilder applications on the server is exactly the same as the one pointed in the Cordova Version
field in the project's properties. As you have noticed, for Cordova 3.5 it is also said (Android 3.5.1). This means that for iOS and WP8 we use the official Cordova 3.5 version framework and for Android, we use Cordova 3.5.1 instead of 3.5 (due to important security fixes, introduced there). However, if you want the check the sources of the Cordova framework, used on our build machines, you can check this github repositories (cordova-ios
). The different branches represent the bits, deployed with your application depending on the selected in the project's properties Cordova Version.
Further, currently we are using XCode 5 for building iOS applications. However, this will change in the future as we have already planned the migration to XCode 6.
As for other libraries and tools, I am afraid I cannot provide this information. Instead, I would suggest you to point the exact issues you are experiencing with plugins and provide steps in order to reproduce them on our side. Having this information, we might be able to help or find a workarounds for you.
