I am have packaged up and am trying to deploy using android studio v3.6.3, I have followed the instructions carefully.

After entering the the following information in my build.gradle

buildscript {
    repositories {
    	google()
    	jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.3'
    }
}

android {
    compileSdkVersion 29
    buildToolVersion '29.0.3'
    //useLibrary 'org.apache.http.legacy'
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 29
    }

I then have made sure i entered the following in my gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip

I've also followed the steps you need to do in the SDK Manager, ticked Andoid 9.0 and 10.0, then in the tools tab, have 28.0.3 installed and 29.0.3.

However... I get the following build/sync error

org.gradle.internal.metaobject.AbstractDynamicObject$CustomMessageMissingMethodException: Could not find method buildToolVersion() for arguments [29.0.3] on object of type com.android.build.gradle.internal.dsl.BaseAppModuleExtension.

Bear in mind, I get the issue regardless of using 28+28.0.3 or 29+29.0.3

Please help!
