Robotium : Use in a third-party project

As I'm doing some unit test on Android, I usually use Robotium.

The core of this tool is really powerful but I made some helper classes and I would like to export them in a separate project so I can re-use them in all my projects.

So I created a new Android Studio library project in order to put my classes inside.

My build.gradle is like:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:22.1.1'
    compile 'com.android.support:support-v4:22.1.1'
    compile 'com.jayway.android.robotium:robotium:5.3.1'
}

And my classes are under my package (modoule/src/main/java/package/).

The thing is, my classes are using some Robotium objects (like Solo) and my project can't resolve the import com.robotium.solo.Solo;

I'm stuck on that. The goal is not to do unit test, but to do a kind of plug-in for Robotium that I will use in my projects by adding this to their build.gradle

dependencies {
    ...
    androidTestCompile 'com.jayway.android.robotium:robotium:5.3.1'
    androidTestCompile 'mytools:module:version'
}

What might be wrong?

I think the object Solo can't be access in the scope "compile".

You can use the following dependency in replacement:

dependencies { 
     compile 'com.jayway.android.robotium:robotium-solo:5.3.1'
}

Enjoy :)
