ButterKnife Code Challenge does not compile with annotations.

The first code challenge with ButterKnife doesn't compile with the following code and error message:

Compiler Output

./MovieActivity.java:7: error: cannot find symbol
    @InjectView(R.id.movieTitle) TextView mTitleLabel;
     ^
  symbol:   class InjectView
  location: class MovieActivity
./MovieActivity.java:8: error: cannot find symbol
    @InjectView(R.id.movieImage) ImageView mMovieImage;
     ^
  symbol:   class InjectView
  location: class MovieActivity
2 errors

The weird thing is that this code works fine in a later code challenge that builds on top of this code.

MovieActivity.java 
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.ImageView;

public class MovieActivity extends Activity {
    @InjectView(R.id.movieTitle) TextView mTitleLabel;
    @InjectView(R.id.movieImage) ImageView mMovieImage;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
        ButterKnife.inject(this);
        // The rest of the code is omitted for brevity :)
      ButterKnife.inject(this);
    }
}
activity_movie.xml 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        android:text=""
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

    <ImageView
        android:id="@+id/movieImage"
        android:layout_width="wrap_content"

        android:layout_centerHorizontal="true"
        android:id="@+id/linearLayout">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:id="@+id/textView"

        <TextView

            android:layout_height="wrap_content"
            android:text=""

I took a look at the challenge. It's accepting the current annotation @BindView though it's inconsistent with with asking for ButterKnife.inject() instead of ButterKnife.bind() in the first step.
