Multiple versions of same library

Question

I have project A, which used to have module A1, that used dagger v. 1.2.2. Now I'd like to add to project A, module A2, that has dependency on dagger v. 2.0. But I can't because these two dagger libs are in conflict. Can I approach somehow multiple versions of library in different android modules?

Answer 1

You can't have both.

You need to exclude the conflicting libraries from dependencies:

configurations {
    all*.exclude group: 'com.google.android', module: 'support-v4'
}

dependencies {
    compile 'com.android.support:support-v4:13.0.0'
}

OR

dependencies {
    compile("org.gradle.test.excludes:api:1.0") {
        exclude module: 'shared'
    }
}
