Buck: Cannot access android.support.v4.app.TaskStackBuilder

[arjunpola]

I am trying to convert the default Empty Application example from Android Studio to use Buck build.
I added the support library jars and aar files. But when I try to build the app I get the following error:

OUTPUT:

GradleToBuck/app/src/main/java/com/example/gradletobuck/MainActivity.java:7: error: cannot access android.support.v4.app.TaskStackBuilder
public class MainActivity extends AppCompatActivity {
^

Code available Here
Any help would be greatly appreciated.
Thank You

Along with appcompat aar, you also need to add following aars

1. support core utils
2. support core ui
3. support fragment
4. support compat
5. support vector drawable
