Gradle dependencies exclude

Question

For some reason I have using java 1.7 to compile my project, but I'm facing duplicate entry error when compile the project. Below is my dependencies tree that showing the duplicate.

+--- com.google.firebase:firebase-analytics:10.2.0
|    +--- com.google.firebase:firebase-common:10.2.0
|    |    +--- com.google.android.gms:play-services-basement:10.2.0
|    |    |    \--- com.android.support:support-v4:24.0.0
|    |    |         \--- com.android.support:support-annotations:24.0.0
|    |    \--- com.google.android.gms:play-services-tasks:10.2.0
|    |         \--- com.google.android.gms:play-services-basement:10.2.0 (x)
|    +--- com.google.firebase:firebase-analytics-impl:10.2.0
|    |    +--- com.google.android.gms:play-services-basement:10.2.0 (x)
|    |    +--- com.google.firebase:firebase-iid:10.2.0
|    |    |    +--- com.google.android.gms:play-services-basement:10.2.0 (x)
|    |    |    \--- com.google.firebase:firebase-common:10.2.0 (x)
|    |    +--- com.google.firebase:firebase-common:10.2.0 (x)
|    |    \--- com.google.android.gms:play-services-tasks:10.2.0 (x)
|    \--- com.google.android.gms:play-services-basement:10.2.0 (x)

I have tried to add exclude when I compile the firebase-analytics libs, but it looks like only the first layer will be excluded, and not all. Can anyone help?

compile ('com.google.firebase:firebase-analytics:10.2.0'){
exclude group: 'com.google.android.gms', module: 'play-services-basement:10.2.0'
}

dependencies block:

dependencies {
    compile project(":core")
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.google.code.gson:gson:2.7'
    compile ('com.google.firebase:firebase-core:10.2.0'){
        exclude group: 'com.google.android.gms', module: 'play-services-basement'
    }
    compile fileTree(dir: "${rootProject.projectDir}/android-libs", include: ['*.jar'])
    compile "org.slf4j:slf4j-android:1.7.10"
}

You can try to use configuration-wide exclusion as follows:

configurations.all {
    exclude group: 'com.google.android.gms', module: 'play-services-basement'
}

Or just exlude it from compile configuration only:

configurations {
    compile.exclude group: 'com.google.android.gms', module: 'play-services-basement'
}
