`AutoValueGson_MyAdapterFactory` not found about auto-value-gson HOT 7 CLOSED

Ahh, yes, this is actually how it's designed to work. Unfortunately,
without that static factory method in the class, there's no way for the
type adapter factory to access the generated package private type adapter
reliably (we can't guarantee your factory is in the same package as all of
your models).

We've been talking about a reflection based solution for this, but for now
all of your AutoValue annotated classes need static type adapter methods.

You can see here
https://github.com/sandboxing/testing-auto-value-gson/commits/master
the only difference between the failing and fixed build.

Basically, if I, in an other class, created a static typeAdapter creator
as so

public static TypeAdapter<Foo> typeAdapter(Gson gson) {
    return new AutoValue_Foo.GsonTypeAdapter(gson);
}

Then, the @GsonTypeAdapterFactory would generate the Factory constructor
as expected, but I wanted to the use @GsonTypeAdapterFactory so I would
not have to set the typeAdapter for every class.

Isn't it a bug?

Looks fine to me. Have you built the project? When you first write it it will show up as unfound because it doesn't get generated until you build.

I had working after building this project, thanks a lot.

However, I cannot have it working on my project. I tried to isolate as much as I could here: https://github.com/sandboxing/testing-auto-value-gson ※ Sorry, I should have done it the first time

I get the following error when I try to build the project (./gradlew build) and I cannot find out what is missing here

app/src/main/java/autovalue/testing/oldering/io/myapplication/AutoValueGsonTypeAdapterFactory.java:9: error: cannot find symbol
        return new AutoValueGson_AutoValueGsonTypeAdapterFactory();

Confirmed on a CircleCI build to be sure it was a local problem. https://circleci.com/gh/sandboxing/testing-auto-value-gson/5

@rharter You must have a lot on your plate and I know I screwed up not showing the minimised version of my project at first but I would really appreciate any help finding what is missing in my configuration.

So I got it working but I am not sure I should be satisfied with the step I took.

    public static TypeAdapter<Foo> typeAdapter(Gson gson) {
        return new AutoValue_Foo.GsonTypeAdapter(gson);
    }

Then, the @GsonTypeAdapterFactory would generate the Factory constructor as expected, but I wanted to the use @GsonTypeAdapterFactory so I would not have to set the typeAdapter for every class.

The generated code is below. Why would it depend on Foo if "auto-value-gson can create a single TypeAdapterFactory so that [I] don't have to add each generated TypeAdapter to [my] Gson instance manually."

public final class AutoValueGson_AutoValueGsonTypeAdapterFactory extends AutoValueGsonTypeAdapterFactory {
  @Override
  @SuppressWarnings("unchecked")
  public <T> TypeAdapter<T> create(Gson gson, TypeToken<T> type) {
    Class<T> rawType = (Class<T>) type.getRawType();
    if (Foo.class.isAssignableFrom(rawType)) {
      return (TypeAdapter<T>) Foo.typeAdapter(gson);
    } else {
      return null;
    }
  }
}

Isn't there something wrong or am I misunderstanding its usage?

I see better now. Thank you for the follow.
