Databinding Android Studio Gradle 3.0.1

Question

Since updating my gradle from 2.2.3 to 3.0.1 databanding has been generating the BR class in the wrong place resulting in cannot find symbol class BR

public abstract class BaseBindingFragment<T, K extends ViewDataBinding> extends BaseFragment<T> {

protected K mBinding;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    mBinding = DataBindingUtil.inflate(inflater, getLayoutResourceId(), container, false);
    mFragmentRootView = mBinding.getRoot();

    // Setup references to views within this fragment
    ButterKnife.bind(this, mFragmentRootView);
    initWidgets(mFragmentRootView);

    return mFragmentRootView;
  }
}

<data>
    <variable
        name="handler"
       type="com.mypackage.fragments.EditBillPaymentsFragment" />

    <variable
        name="billpayment"
        type="com.mypackage.database.models.Bills" />

</data>

            <EditText
                android:id="@+id/et_account_number"
                style="@style/editBill"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:ems="10"
                android:enabled="false"
                android:inputType="textPersonName"
                android:text="@={billpayment.payee.accountNumber}" />

Answer 1

BR file is generated at

com.yourpackage.BR;

So if you have wrong import then change it.

import com.yourpackage.BR;
