Unity 2018.4 & Multi-Dex

Unity Engine
,
1

Hi,
I’m trying to enable multiDex for my android build, I enabled Custom Gradle Template but I’m getting this error when I build:
A problem occurred evaluating root project ‘gradleOut’.
> Plugin with id ‘com.android.library’ not found.

Also when Custom Gradle Template is enabled, Android dependency Resolver shows “Resolution Succeed” but don’t resolve the dependencies!

When I disable Custom Gradle Template, Android dependency Resolver resolves the dependencies but I can’t build because of the Dex 64k limit!
I’m using Unity 2018.4.28f1
Any idea what’s going wrong?

Here is my custom template:

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

// Android Resolver Repos Start
([rootProject] + (rootProject.subprojects as List)).each {
    ext {
        it.setProperty("android.useAndroidX", true)
        it.setProperty("android.enableJetifier", true)
    }
}
([rootProject] + (rootProject.subprojects as List)).each { project ->
    project.repositories {
        def unityProjectPath = $/file:///**DIR_UNITYPROJECT**/$.replace("\\", "/")
        maven {
            url "https://maven.google.com"
        }
        maven {
            url "https://jcenter.bintray.com" // Assets/GoogleMobileAds/Editor/VungleMediationDependencies.xml:7
        }
        mavenLocal()
        jcenter()
        mavenCentral()
    }
}
// Android Resolver Repos End

Check your base gradle template. com.android.tools.build:gradle should beclasspathin buildscript.
