More than one file was found with OS independent path 'protobuf.meta'

I'm seeing some issues with compatibility between com.google.android.gms:play-services-auth:11.6.0 and com.android.support.test.espresso:espresso-core:3.0.1 when used as dependencies on an android library module

I'm getting this error:

Execution failed for task ':mylibrary:transformResourcesWithMergeJavaResForDebugAndroidTest'.   
More than one file was found with OS independent path 'protobuf.meta'

when I try to execute ./gradlew :myLibrary:connectedAndroidTest

Here's a barebones build.gradle that I've reproduced the problem on:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 26



    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.google.android.gms:play-services-auth:11.6.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.1'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

I don't think I can exclude either of these files as the contents is different.
