/*
Since the Kover and Android plug-ins can be in different class loaders (declared in different projects), the plug-ins are stored in a single instance in the loader of the project where the plug-in was used for the first time.
Because of this, Kover may not have direct access to the Android plugin classes, and variables and literals of this types cannot be declared .

To work around this limitation, working with objects is done through reflection, using a dynamic Gradle wrapper.
