Android espresso-contrib gradle build failing

Question

I'm trying to learn android espresso.. I followed some basic tutorials and it was working fine. But now I want to do some tests on the android navigation drawer. For that I need to use gradle dependency androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2' but it's causing conflict with other dependencies. My gradle file :

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.3"

defaultConfig {
    applicationId "my.com.myapp_android"
    minSdkVersion 18
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}
repositories {
jcenter()
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
//material design
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:support-v4:23.3.0'

//zxing
compile 'com.journeyapps:zxing-android-embedded:3.2.0@aar'
compile 'com.google.zxing:core:3.2.1'

//Testing
// Optional -- Mockito framework
testCompile 'org.mockito:mockito-core:1.10.19'
androidTestCompile 'com.android.support:support-annotations:23.3.0'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support.test:rules:0.4.1'
// Optional -- Hamcrest library
androidTestCompile 'org.hamcrest:hamcrest-library:1.3'
// Optional -- UI testing with Espresso
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2'
// Optional -- UI testing with UI Automator
androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'




//inMarketSDK
//compile group: 'com.inmarket', name: 'm2msdk', version: '2.29', ext: 'aar'

}

Error is something like this:

Error:Conflict with dependency 'com.android.support:support-v4'. Resolved versions for app (23.3.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.
Error:Conflict with dependency 'com.android.support:appcompat-v7'. Resolved versions for app (23.3.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

followed this : link for espresso install

I also tried to exclude annotation dependency :

 androidTestCompile ('com.android.support.test.espresso:espresso-core:2.2.2')  {
    // Necessary if your app targets Marshmallow (since Espresso
    // hasn't moved to Marshmallow yet)
    exclude group: 'com.android.support', module: 'support-annotations'
}

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2')
        {
            // Necessary if your app targets Marshmallow (since Espresso
            // hasn't moved to Marshmallow yet)
            exclude group: 'com.android.support', module: 'support-annotations'
        }

Error message says conflict with `com.android.support:support-v4` and `com.android.support:appcompat-v7`. So try to exclude them too. — nenick, May 20 '16 at 05:19

TL;DR;

New version of espresso-contrib 2.2.2 library has now dependency on com.android.support:appcompat-v7:23.1.1 resulting into conflict when using different version of appcompat-v7 in our compile time dependency like below:

dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     testCompile 'junit:junit:4.12'
     compile 'com.android.support:appcompat-v7:23.4.0'

     androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.2'
}

To avoid conflict when we exclude appcompat-v7 dependency from espresso-contrib like below it breaks again due to some value dependencies on design support lib.

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
    exclude module: 'appcompat-v7'
}

Error:

Error:(69) Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.AppCompat.Display1'.

Root cause:

This is because the design support lib has dependency on appcompat-v7.
So,when we exclude 'appcompat-v7' module from espresso-contrib dependencies(like above) , the design support lib downloaded as part of transitive dependency of espresso-contrib lib couldn't find the compatible version of appcompat-v7 lib(23.1.1) it is using internally in its resources files and thus gives out the above error.

So, the solution to above problem is to exclude 'design-support' lib dependency from espresso-contrib like below:

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
    exclude module: 'design'
}

That solves the conflict problem!

LONGER VERSION (in case someone is interested):

To found out the reasons of various conflict issues we face when using `espresso-contrib' library i have created sample app to find out the root cause.

Step 1:Using Espresso-Contrib Lib version 2.2.1

Created App to use 'espresso-contrib' lib version 2.2.1 by adding following lines in app/build.gradle file:

dependencies {
     compile fileTree(dir: 'libs', include: ['*.jar'])
     testCompile 'junit:junit:4.12'

     androidTestCompile 'com.android.support.test.espresso:espresso-contrib:2.2.1'

}

Note: In this case,I am not importing any other support library components like
appcompat-v7,recyclerview-v7,etc.

The dependency graph for the above setup looks like below:

As can be seen that espresso-contrib 2.2.1lib has transitive dependencies on version 23.0.1 of
support-v4,recyclerview-v7,support-annotations ,etc.

As i am not defining dependencies for recyclerview-v7,support-annotations in my project the above setup would work just fine.

But when we define those as compile dependencies [like below] in our project we get version conflict issues as stated in your question.

compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:support-v4:23.3.0'

To avoid those conflicts we add below line to our espresso-contrib lib:

    androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.1'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
}

This makes sure those dependencies aren't downloaded as part of espresso-contrib transitive dependencies.
Everything runs fine with above setup.No issues!

Step 2: Using Espresso-Contrib lib version 2.2.2

Changed App's build.gradle to use 'espresso-contrib' lib version 2.2.2 by changing the previous build.gradle file:

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:support-v4:23.3.0'
testCompile 'junit:junit:4.12'

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'support-v13'
    exclude module: 'recyclerview-v7'
  }
}

But when i build project using above setup..build fails with error posted in question..

Error:

Error:Conflict with dependency 'com.android.support:appcompat-v7'. Resolved versions for app (23.3.0) and test app (23.1.1) differ. See http://g.co/androidstudio/app-test-app-conflict for details.

So, looking at error i added one more line to above build.gradle:

exclude module: 'appcompat-v7' (inside androidTestCompile block of espresso-contrib)

But that doesn't resolves the conflict issue and i get value dependencies error posted in comments.
So i check for dependency graph of my app again:

As can be seen now that espresso-contrib 2.2.2 lib has now transitive dependency on com.android.support:design:23.1.1 causing the above conflict.

So, we need to add below line inside androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.2') block:

exclude module: 'design'

This resolves the conflict issue in lib version 2.2.2!

For some reason, it has also started to happen to me out of the blue.

The only thing that solved it was to invalidate caches and restart

do below

androidTestCompile ('com.android.support.test.espresso:espresso-contrib:2.2.1'){
    exclude module: 'support-annotations'
    exclude module: 'support-v4'
    exclude module: 'recyclerview-v7'
}

Well, I tried excluding but when I write this `exclude group: 'com.android.support', module: 'appcompat-v7'` it brakes some values dependencies. – HirenPatel_ May 23 '16 at 15:38
I tried this ` transitive = false` and it worked , though. But not sure if this is a good solution – HirenPatel_ May 23 '16 at 15:39
