Google Auto Factory: not annotated with @Provided?

Question

So I'm trying out google auto factory but I get a strange error.

Factory class:

@AutoFactory(
    className = "MembersAdapterFactoryImpl"
)
public class MembersAdapter extends ArrayAdapter<Member> {

    /**
     * Get an instance of the helper
     */
    private MembersAdapterHelper mMembersAdapterHelper;

    public MembersAdapter(@Provided MembersAdapterHelper membersAdapterHelper,
                          Context context,
                          int resource,
                          List<Member> members){
        super(context, resource, members);
        mMembersAdapterHelper = membersAdapterHelper;
    }
}

Generated class:

package me.magneto.groups.adapters;

import javax.annotation.Generated;
import javax.inject.Inject;
import javax.inject.Provider;
@Generated("com.google.auto.factory.processor.AutoFactoryProcessor")
public final class MembersAdapterFactoryImpl {
  private final Provider<MembersAdapterHelper> membersAdapterHelperProvider;
  @Inject
  public MembersAdapterFactoryImpl(Provider<MembersAdapterHelper> membersAdapterHelperProvider) {
    this.membersAdapterHelperProvider = membersAdapterHelperProvider;
  }
  public MembersAdapter create(android.content.Context context, int resource, java.util.List<me.magneto.groups.models.group.Member> members) {
    return new MembersAdapter(membersAdapterHelperProvider.get(), context, resource, members);
  }
}

Which seems perfectly fine but I am getting this exception.

I am listing this as a compile within my android gradle file:

// factories
compile 'com.google.auto.factory:auto-factory:0.1-beta1'

// dagger
compile 'com.squareup.dagger:dagger:1.2.0'
provided 'com.squareup.dagger:dagger-compiler:1.2.0'

Any clues to why the compiler would complain?

Answer 1

It looks like the problem is mostly with annotation processing / dagger / missing javax jars.

I should thank cypressious on Github for posting his gradle build.gradle file, lifesaver.

https://github.com/evant/gradle-retrolambda/issues/31

1. You need to use

   (i) With Dagger 2.0 the dependency problem still persists but you don't need any apt. so skip ahead to 3.

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

2. Looks like using 'provided' for dependencies won't work with Google auto factory and need to use 'apt' plugin for dependencies instead. This includes dagger (if you're using it which I'm assuming) resulting in something like

   apt 'com.google.auto.factory:auto-factory:0.1-beta1'
   compile 'com.google.auto.factory:auto-factory:0.1-beta1'
   
   compile 'com.squareup.dagger:dagger:1.2.0'
   apt 'com.squareup.dagger:dagger-compiler:1.2.0'
   

   Now that's another big thing, at Dagger 1.2.1 / 1.2.2 is not supported, so I had to end up using Dagger 1.2.0.

3. The last step you have to take this into your dependencies:

   compile 'javax.annotation:jsr250-api:1.0'

   It looks like the Generated annotation is not included as part of Java8? I'm not 100% of this or this is just how Gradle by default is not including the 'Generated' annotation as part of the annotation processing.

Anyways, after doing those three things Google Auto Factory appears available in my project.
