'Update autovalue generated methods' does not generate Builder method properly

[igorwojda]

setLastName method should be added after running 'Update autovalue generated methods', instead all methods are removed and only setLastName is added (running action the second time generates all method as before, but there is no Update autovalue generated methods)

package com.model;

import com.google.auto.value.AutoValue;
import com.google.gson.annotations.SerializedName;

import javax.annotation.Nullable;

@AutoValue
public abstract class PatientModel {

    @Nullable
    @SerializedName("id")
    public abstract String getId();

    @Nullable
    @SerializedName("first_name")
    public abstract String getFirstName();
    
    @Nullable
    @SerializedName("last_name")
    public abstract String getLastName();

    public static Builder builder() {
        return new AutoValue_PatientModel.Builder();
    }

    @AutoValue.Builder
    public abstract static class Builder {

        public abstract Builder setId(String newId);

        public abstract Builder setFirstName(String newFirstName);

        public abstract PatientModel build();
    }
}
