GenerateTypeAdapter proguard warning

[xdgimf]

Updated to 0.7.0 and got this proguard warnings related to the new annotation @GenerateTypeAdapter. I haven't used it yet so I'm not really sure.

Here's the proguard warning

Warning: library class com.ryanharter.auto.value.gson.GenerateTypeAdapter$1 extends or implements program class com.google.gson.TypeAdapterFactory

Warning: there were 1 instances of library classes depending on program classes.
         You must avoid such dependencies, since the program classes will
         be processed, while the library classes will remain unchanged.

Here's my dependencies

depedencies {
    //...
    compileOnly "com.jakewharton.auto.value:auto-value-annotations:$project.ext.autoValueAnnotationsVersion"
    compileOnly "com.ryanharter.auto.value:auto-value-gson:$project.ext.autoValueGsonVersion"
    annotationProcessor "com.google.auto.value:auto-value:$project.ext.autoValueVersion"
    annotationProcessor "com.ryanharter.auto.value:auto-value-gson:$project.ext.autoValueGsonVersion"
    annotationProcessor "com.ryanharter.auto.value:auto-value-parcel:$project.ext.autoValueParcelVersion"
    //...
    implementation "com.google.code.gson:gson:$project.ext.gsonVersion"
    //...
}

For now I simply ignored the warnings by adding the following rules:

-dontwarn com.ryanharter.auto.value.gson.GenerateTypeAdapter
-dontwarn com.google.gson.TypeAdapterFactory

Edit: Added Gson dependency

Do you have a Gson dependency?

Yes, I have a Gson dependency.

any updates on this?

Only thing I can think of is that proguard is complaining that there's code in the annotations artifact that isn't there at runtime because you're not compiling the annotations. There's a full TypeAdapterFactory implementation in the GenerateTypeAdapter annotation code

Closing this out, but the rules above should suffice. Unfortunately we can't solve this with an embedded proguard file as these would be compileOnly and presumably not reach proguard/R8 tools to index on
