Can't import external project as module in Android Studio 3

Question

I have an app already published on the store, after upgrading to Android Studio 3 (now 3.1) and the forced update of gradle I am unable to import my external projects as modules.

I have tried removing all my modules and adding them one by one, deleting the cache, changing gradle version, and compileSdkVersion but it doesn't work.

When I try to sync gradle I receive some messages like this:

Unable to resolve dependency for ':app@produzioneDebug/compileClasspath': Failed to transform file 'ShareLib-release.aar' to match attributes {artifactType=android-exploded-aar} using transform ExtractAarTransform

This is in my settings.gradle to make external project available:

include ':app'

include ':ShareLib'
project(':ShareLib').projectDir = new File('..//ShareLib//')

This is my build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven { url 'https://maven.fabric.io/public' }

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

You have a lowercase letter in ShareLib at your dependency. If this doesn't solve your problem: Have you tried to use something else than implementation like: api project(':ShareLib:default') ? — P-Zenker, May 18 '18 at 14:59
that one is an editing error, but no I've not tried it. i'll let you know — firegloves, May 18 '18 at 15:00
actually I can't start my project but I have solved as my answer says, thank you for your help :) — firegloves, May 18 '18 at 15:43

I have solved opening modules project one by one and doing this for each one:

Project Structure -> Project -> Gradle Version = 4.7
Settings -> Build, Execution, Deployment -> Compiler -> Uncheck "Configure on demand"
Rebuild project once you can see your .aar file into build/outputs/aar

Then repeat these steps for main project module
