GreenDAO 3.1.1 Annotation processing fails at "[Type] cannot be resolved to a variable"

Any help or guidance would be great; I've recently starting working with GreenDAO (version 3.1.1) using their new annotation processor rather than using the generation projects as the previous versions employed.

All goes well until I try to add custom constructors with class type parameters, or reference other class type functions within the class.

I am met with the following error: 

Found 1 problem(s) parsing "C:\~\authentication\providers\AuthenticationToken.java":
Pb(83) AuthenticationProviderTypes cannot be resolved to a variable
:jroot:greendao FAILED

I'm using:

- GreenDAO 3.1.1
- Android Studio 2.1.3
- buildToolsVersion 23.0.3
- targetCompatibility JavaVersion.VERSION_1_7
- compileSdkVersion/targetSdkVersion 24
- minSdkVersion 19

What I've tried:

- Invalidate cache / restart android studio
- Clean build (like infinity times)
- Removing the custom constructor 
    - Does build, but defeats the point of needing constructor.
- Read through the documentation and added the @Keep annotation.

Here's a shortened example of my entity class:

@Entity(nameInDb = "authentication_token", active = true, createInDb = true)
public final class AuthenticationToken implements Serializable {
    @Unique
    @Id(autoincrement = false)
    private Long id;

    @SerializedName("InstanceAuthenticationType")
    @Convert(converter = AuthenticationProviderTypes.AuthenticationProviderTypeConverter.class, columnType = Integer.class)
    private AuthenticationProviderTypes authenticationType;

    @SerializedName("CustomerCode")
    @Convert(converter = CustomerCode.CustomerCodeConverter.class, columnType = String.class)
    private CustomerCode customerCode;

    @SerializedName("ContactCode")
    @Convert(converter = ContactCode.ContactCodeConverter.class, columnType = String.class)
    private ContactCode contactCode;

    @SerializedName("PortalID")
    private Integer portalID;

    @Generated(hash = 1522783431)
    public AuthenticationToken(Long id, 
        AuthenticationProviderTypes authenticationType, 
        CustomerCode customerCode, 
        ContactCode contactCode, 
        Integer portalID) {
        // generated constructor code; this is fine, works & builds like a champ!
    }

    @Keep
    public AuthenticationToken(AuthenticationProviderTypes preferredProviderType) {
        // After successful build without this constructor
        // I add this constructor to the entity class
        // and it causes the GreenDAO generator / build to fail.
        // without any other changes to the class or code
        authenticationType = preferredProviderType;
    }
}

UPDATE: I'm wondering if this problem is limitation or bug. I removed my custom constructor, created my class instance from the generated empty constructor and set my variable using the generated setter. It works, but goes against the point of having a concrete constructor in an object's logic. I feel this demonstrates the generator knows about and can resolve my AuthenticationProviderTypes class, just not at the constructor level.

Thanks again for any help or suggestions.

Let GreenDao generate its methods .. then implement serializable or parcelable.

Im deleting all generated methods, then call 

./gradlew greendao
