Consider the sample build script shown above that demonstrates the use of type-safe accessors.
The following sample is exactly the same except that is uses the `apply()` method to apply the plugin.
The build script can not use type-safe accessors in this case because the `apply()` call happens in the body of the build script.
You have to use other techniques instead, as demonstrated here:
