build(deps): bump dagger-compiler from 2.16 to 2.21

[dependabot-preview]

Bumps dagger-compiler from 2.16 to 2.21.

Release notes

Sourced from dagger-compiler's releases.

Dagger 2.21

• Build performance improvements (174a7a9b)
  • Separately, there may be an increase in build times for opensource users using javac9 or javac10. Neither javac8 or javac11 should be affected. (96fcce89)
• New validation:
  • Installing a module with scoped bindings that an ancestor component has also installed is now an error. (4695ff51)
  • A warning is now reported if an explicit binding conflicts with an [**Inject**](https://github.com/Inject) binding in an ancestor component. This was never intended to be supported but never checked. Adds a flag to control whether that is a warning or an error. (7f5500fb)
  • Installing a [**ProducerModule**](https://github.com/ProducerModule) in a [**Subcomponent**](https://github.com/Subcomponent) that is already installed in a parent (or earlier ancestor) component is now an error. It is also an error to repeat a [**Module**](https://github.com/Module) that has a binding in [**ProductionScope**](https://github.com/ProductionScope). (68b21537)
• SPI
  • New method: ComponentNode.isSubcomponent() (b6b9dcac)
• Producers
  • Deprecated dagger.producers.internal.Producers.immediateProducer() and dagger.producers.internal.Producers.immediateFailedProducer() in favor of newly added methods with the same names in dagger.producers.Producers (a4914c61) (added in 50d7010f)
• Properly generate components when qualifiers are generated (ab9cdbc2)
• Dagger itself now uses more Dagger (97fce1e3)

Dagger 2.20

• Peformance improvements in annotation processing (8012ab5c)
• Report duplicate bindings only once, not once per request. (623461fb)
• Make sure all processing steps defer elements properly if they have missing types. (3b0fcc82)
• Make [**ProductionComponent**](https://github.com/ProductionComponent) have runtime retention so tools can interpret it like all of the other component annotations (fff65e3c)
• 325b516a:
  • Add module-level validation. When -Adagger.moduleBindingValidation=ERROR or =WARNING is set, then each module is processed as a kind of component (without generating any code) in order to validate the bindings installed by it and all included modules. Any binding graph errors, such as duplicate bindngs (but not including missing bindings), will be reported as errors or warnings depending on the option.
• Report map multibinding contribution errors once regardless of whether the map is requested as Map<K, V>, Map<K, Provider<V>>, or Map<K, Producer<V>>. (350368e6)
• c7e7c4f1:
  • Fixes two bugs related to [**ProductionScope**](https://github.com/ProductionScope) bindings:
    • Where modules with [**ProductionScope**](https://github.com/ProductionScope) bindings are installed in multiple components in the same component ancestry, the binding is now resolved only once and only in the rootmost component.
    • When [**Inject**](https://github.com/Inject) bindings with [**ProductionScope**](https://github.com/ProductionScope) are referenced in a binding graph, the binding is now resolved in the rootmost ProductionScope component.
• 221f000e:
  • dagger.android code can no longer use the AndroidInjector.Factory<? extends Activity> format to bind injector factories. See https://google.github.io/dagger/android and the 2.19 release notes for information on how to migrate.
  • Adds an ErrorProne refactoring for migrating from AndroidSupportInjectionModule (which now is functionless) to AndroidInjectionModule. See these docs for how to apply the refactoring to your codebase if you're on dagger-compiler-2.20.
• Removed dagger.releaseablereferences (a72c3428)
• Removed the -Adagger.floatingBindsMethods flag added in 2.17 (https://github.com/google/dagger/wiki/Dagger-2.17-@Binds-bugs) (bc8dd5bd)

Dagger 2.19

• dagger.android has a new format for binding AndroidInjector.Factorys:
  • Instead of returning AndroidInjector.Factory<? extends Activity> (or Service, Fragment, etc), return just AndroidInjector.Factory>
  • Instead of using [**ActivityKey**](https://github.com/ActivityKey) (or [**ServiceKey**](https://github.com/ServiceKey), [**FragmentKey**](https://github.com/FragmentKey), etc), use [**ClassKey**](https://github.com/ClassKey). The dagger.android map keys (with the exception of [**AndroidInjectionKey**](https://github.com/AndroidInjectionKey) are now deprecated
  • If you use [**ContributesAndroidInjector**](https://github.com/ContributesAndroidInjector), there's nothing to do. We have updated the output to match the new format
  • We have provided an ErrorProne refactoring for migrating to the new format of binding AndroidInjector.Factorys with dagger.android. See these docs for how to apply the refactoring to your codebase if you're on dagger-compiler-2.19. (02dc4a7f)
  • In the next release (2.20), we will remove the old format. This will allow us to support AndroidX packages better.
  • For the complete docs, visit https://google.github.io/dagger/android
• Avoid some thrown errors during Dagger compilation for invalid modules. (4df5adf9)
• Some formatting fixes even when the formatter is turned off

Dagger 2.18

• Producers:
  • Added [**CancellationPolicy**](https://github.com/CancellationPolicy) annotation, which can be used to make a production component or subcomponent allow cancellation of its subcomponent(s) to propagate up to it and cancel its nodes as well. (f5c04a54)
  • Producer cancellation is now deterministic; cancelling an entry point of a production component will now ensure that it cancels all running tasks for that component and prevents any further tasks for that component from starting. For components with more than one entry point, this does mean that cancelling one entry point will cancel all entry points for the component. For production subcomponents, cancellation of a subcomponent entry point will not propagate cancellation to tasks owned by an ancestor component. (ea48dfd4)
• Better Errors:
  • Change constructor bindings and dependency requests from void package.Class.<init>(params) to package.Class(params), which looks more like how Java users think of constructors. (d31943c2)
  • Report errors on members injection component methods and MembersInjector requests that have qualifiers. (3be3073f)
