Dagger 2 no classes generated

Question

I want to try something new and use Dagger 2 as my DI framework. So I have the following pom and the "hello world" coffee maker classes (http://google.github.io/dagger/) in my projekt.

But when I do a mvn clean install no classes get generated. As far as I unterstood there should be a "Dagger_CoffeeShop" class generated. Hmmm ... what am I missing?

Answer 1

For those using Gradle: Make sure you are referencing the Dagger dependencies as following:

compile 'com.google.dagger:dagger:2.0.2'
apt 'com.google.dagger:dagger-compiler:2.0.2'

And in the case if you are running into apt not supported, add

1) Into module app\build.gradle:

apply plugin: 'com.neenbedankt.android-apt'

2) Into project \build.gradle:

buildscript {
    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}
