Espresso-contrib cannot inflate RecyclerView with IllegalStateException (Unable to find LayoutManager)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Set up an activity that contains a RecyclerView exactly as shown in the 
official examples.
2. Run the app and see that it works.
3. Write a test that starts that activity with the following dependencies:

    androidTestCompile 'com.android.support.test:runner:0.2'
    androidTestCompile 'com.android.support.test:rules:0.2'
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
    androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2'

4. Run the test and see that there are no problems.
5. Add the following dependency:

    androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2'

6. Run the test and see that the RecyclerView could not be inflated because the 
LayoutManager instance couldn't be found.

What is the expected output? What do you see instead?

The test should work exactly as it did before espresso-contrib was included in 
the dependencies. Instead, the test raise an IllegalStateException:

Can you please bump the runner/rules dep to 0.3:

androidTestCompile 'com.android.support.test:runner:0.3'
androidTestCompile 'com.android.support.test:rules:0.3'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-intents:2.2'

Does this fix the issue?

Bumping rules/runner to 0.3 doesn't seem to change anything.

As an experiment, I also tried to set the LayoutManager in the xml:

    <android.support.v7.widget.RecyclerView
        android:id="@+id/my_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical"
        android.support.v7.recyclerview:layoutManager="android.support.v7.widget.LinearLayoutManager"
        tools:listItem="@layout/my_list_item" />

This made no difference. I've also played with adding/removing different 
attributes on the RecyclerView, but still haven't had any luck.

I've attached screenshots to show exactly what is happening where the error 
occurs.

It appears the version of recyclerview that is included by espresso-contrib is 
messing with the version I've included in my dependencies (22.2.0), and is 
attempting to reference a default layoutmanager resource that doesn't exist in 
my project. I am able to work around the issue by excluding transitive 
dependencies for espresso-contrib:

    androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.2') {
        exclude group: 'com.android.support'
    }

espresso-contrib uses 22.2.0 for android.support.*, so this should not be an 
issue. I'll have a closer look and try to reproduce it.

In case anybody has the same issue, I found this trick that seems to fix the 
problem:
androidTestCompile('com.android.support.test.espresso:espresso-contrib:2.0') {
    exclude group: 'com.android.support', module: 'appcompat'
    exclude group: 'com.android.support', module: 'support-v4'
    exclude module: 'recyclerview-v7'
}
