Google Auto Factory: not annotated with @Provided?

Question

So, I'm trying to use google auto factory, but I get a weird 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); } } 

This seems to be fine, but I get this exception.

I list this as a compilation in myroid 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 why the compiler will complain?

Answer 1

It seems like the problem is mainly related to annotation processing / dagger / missing javax banks.

I have to thank kipress on Github for posting his gradle build.gradle file, lifesaver.

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

• You need to use

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

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

• It seems that using “provided” for dependencies will not work with Google auto factory and instead you need to use the “apt” plugin for dependencies. This includes a dagger (if you use it, which I assume), which leads to 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 another important thing is not supported in Dagger 1.2.1 / 1.2.2, I ended up having to use Dagger 1.2.0.

• The last step you should take in your dependencies:

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

  It seems that the generated annotation is not included as part of Java8? I am not 100% of this or this is just like gradle by default does not include the "Generated" annotation as part of the annotation processing.

In any case, following these three steps, the Google Auto factory will appear in my project.
