Dagger 2.51

New Dagger Features

• Added a @LazyClassKey annotation that supports using class names as a map key. Unlike the existing @ClassKey, the map generated by @LazyClassKey won’t eagerly load all of the classes for the keys. This can be useful in situations or environments where classloading can be expensive, such as on Android. For more information, see https://dagger.dev/dev-guide/multibindings

Potential breaking changes

• Protected fields using @Inject are now banned in Kotlin classes. This is because Kotlin protected fields are not accessible by code in the same package, unlike Java. This has been working up to this point because Dagger generates Java code, but that is unintentional and would break if Dagger switched to generate Kotlin code.(408431a3b)

New Hilt Features

• Fixed #3197: Used the new @LazyClassKey Dagger feature to remove the keep rule for @HiltViewModel class names. This allows obfuscation of @HiltViewModel annotated ViewModel class names with R8. (0786d0af5)
• Added @SkipTestInjection which can be used for skipping test injection in Hilt Android tests, which may be useful if building separate custom test infrastructure to inject the test class from another Hilt component. (c40811e71)

Dagger bug fixes

• Improve Dagger MissingBinding error messages to give more information and be more consistent. (c8722386a)
• Fixed #4201: Suppress warning for casting in Dagger generated code. (813ffced8)
• Fixed #4203: Removes @Deprecated annotation causing warnings (3cbc94ad3)
• Fixed #4199: Support member injections from type aliased superclass (662d82359)
• Complete Ksp support for Dagger Android: Added a Ksp Processor for Dagger Android ProguardProcessor that was previously missed. The ProguardProcessor is a Dagger Android implementation detail that makes sure the AndroidInjector works correctly when shrinking tools obfuscate @ContributesAndroidInjector annotated injector class names. (e71de27a1)

Dagger 2.50

Dagger

Potential breaking changes

• Introduced a new dagger.internal.Provider to facilitate future support for jakarta.inject.Provider types. There should be no visible changes at this time, though with such a large change there is a risk of unanticipated version compatibility issues across libraries built with different Dagger versions. (75d3cbcf9)
• Flip the default for -Adagger.explicitBindingConflictsWithInject to enabled. This flag fixes a bug where an explicit binding like an @Provides should conflict with @Inject bindings if the @Inject is actually used in a parent component. (8372c6308)

Bug fixes

• Fixed the error message for an @Binds @IntoSet implementation with duplicate bindings. (8d0122322)

Dagger 2.49

Dagger

New features:

• Fixed #4044: Add support for KSP with dagger.android (832717767).

Potential breaking changes:

• Dagger’s generated component no longer contains deprecated no-op module setter methods for modules that have only static/abstract @Provides/@Binds methods (ed47d4b88).

  Note: If you hit this issue, the fix is to remove the call to the setter method in your code. For example:

  MyComponent component =
      DaggerMyComponent.builder()
  -        .moduleWithOnlyStaticOrAbstractMethods(new ModuleWithOnlyStaticOrAbstractMethods())
          .build();

  These setter methods were already no-ops (i.e. Dagger just ignored them), so removing it should not cause any functional changes.
