Model for components that only contains build-time properties
Components can be APKs, AARs, test APKs, unit tests, test fixtures, ...
This is the parent interface for all components. From there, there is a first fork, via[Variant](https://developer.android.com/reference/tools/gradle-api/8.13/com/android/build/api/variant/Variant)which are production build output (APKs, AARs), and[TestComponent](https://developer.android.com/reference/tools/gradle-api/8.13/com/android/build/api/variant/TestComponent)that are test components.[TestFixtures](https://developer.android.com/reference/tools/gradle-api/8.13/com/android/build/api/variant/TestFixtures)is another separate component. See these types for more information.
See[Variant](https://developer.android.com/reference/tools/gradle-api/8.13/com/android/build/api/variant/Variant)for more information on accessing instances of this type.
The properties exposed by this object do not impact the build flow. They are directly set on tasks via[org.gradle.api.provider.Property](https://docs.gradle.org/current/javadoc/org/gradle/api/provider/Property.html)linking.
For example:
```verilog
tasks.register(...) {
input.set(myComponent.someProperty)
* }
```
Because links between[org.gradle.api.provider.Property](https://docs.gradle.org/current/javadoc/org/gradle/api/provider/Property.html)objects are lazy, they are ordering-safe and any plugins can set new values or link them into their own tasks in any order.
However, calling[org.gradle.api.provider.Property.get](https://docs.gradle.org/current/javadoc/org/gradle/api/provider/Property.html#get--)during configuration on these properties is not safe as the values could be linked to task output (that requires the task to run).
The object also exposes read-only version of the properties exposed by[ComponentBuilder](https://developer.android.com/reference/tools/gradle-api/8.13/com/android/build/api/variant/ComponentBuilder). These will contain the final values set after all[AndroidComponentsExtension.beforeVariants](https://developer.android.com/reference/tools/gradle-api/8.13/com/android/build/api/variant/AndroidComponentsExtension#beforeVariants(com.android.build.api.variant.VariantSelector,kotlin.Function1))callbacks have been executed. It is safe to read these values during configuration time.
