=================================

[Dagger2 site ](http://google.github.io/dagger/)

[See branch for ewerk plugin version](https://github.com/griffio/dagger2-example/tree/plugin)

Since 2.0 release:- Dagger generates components prefixed with just "Dagger" instead of "_"

[Truth Assert](http://google.github.io/truth/)

Currently uses Truth.assertThat(...)

* @Component

  * @Module

    * @Provides

The TerrestrialPlanetsModule, for example, provides a singleton named "Mercury" etc.

```java

@Module

public class TerrestrialPlanetsModule {

    @Provides

    @Singleton

    @Named("Mercury")

    Planet first() {

        return new Mercury();

    }

    @Provides

    @Singleton

    @Named("Venus")

    Planet second() {

        return new Venus();

    }

    @Provides

    @Singleton

    @Named("Earth")

    Planet third() {

        return new Earth();

    }

    @Provides

    @Singleton

    @Named("Mars")

    Planet fourth() {

        return new Mars();

**Gradle build**

* The dagger compiler (com.google.dagger:dagger-compiler) annotation processor is only added to the java compiler task classpath using the configuration "compileDagger".

* Application only runs with (com.google.dagger:dagger, javax.inject and com.google.guava as used in the application)

* The sourceSet for generated code is under 'src/dagger/java'

```

./gradlew run

```

```groovy

  id 'java'

  id 'application'
