*** ** * ** ***

Exception thrown when users are trying to access `https://developer.android.com/reference/tools/gradle-api/9.6/com/android/build/api/variant/VariantBuilder` properties.

`https://developer.android.com/reference/tools/gradle-api/9.6/com/android/build/api/variant/VariantBuilder` properties are defined as kotlin properties so users can use simple assignment rather than calling a set function. However, those properties can only be set.

It is not safe to read the property value as other registered `https://developer.android.com/reference/tools/gradle-api/9.6/com/android/build/api/variant/AndroidComponentsExtension#beforeVariants(com.android.build.api.variant.VariantSelector,kotlin.Function1)` callbacks can run later and change the value.

If you need the final value of a property, it is most likely available in the `https://developer.android.com/reference/tools/gradle-api/9.6/com/android/build/api/variant/Variant` hierarchy accessible through the `https://developer.android.com/reference/tools/gradle-api/9.6/com/android/build/api/variant/AndroidComponentsExtension#onVariants(com.android.build.api.variant.VariantSelector,kotlin.Function1)` callbacks.
