未生成Dagger 2组件类

Question

我目前正在学习dagger2，但我有问题是未生成daggercomponent类，我不知道原因

implementation 'com.google.dagger:dagger-android:2.27'
implementation 'com.google.dagger:dagger-android-support:2.27'  
annotationProcessor 'com.google.dagger:dagger-android-processor:2.27'

---

public class Nugets {
    @Inject
    public Nugets() {
    }
}

---

public class Water {

    @Inject
    public Water() {
    }
}

---

public class Coffee {

    Nugets nugets;
    Water water;

    @Inject
    public Coffee(Nugets nugets, Water water) {
        this.nugets = nugets;
        this.water = water;
    }
}

---

@Component
public interface CoffeeComponent {
    Coffee getCoffee();
}

当我尝试找到DaggerCoffeeComponent类时，我没有找到它。注意我重建项目

Answer 1

您必须实施dagger而不是dagger-android。不要忘记进行项目或重建
