How can I get this Android Gradle build to work?

Question

I'm not using Android Studio, I'm using a command line build with Android, Java, and Gradle, on a Windows machine.

I'm using the very latest Android SDK. Gradle version 5.6.4. Using a simple skeletal Android Gradle app. With these files:

buildscript {
    repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.4.1'
}
}

allprojects {
    repositories {
    google()
    jcenter()
   }
}

task clean(type: Delete) {
delete rootProject.buildDir
}


apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion '30.0.2'

defaultConfig {
    minSdkVersion 14
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
}

buildTypes {
    release {
    minifyEnabled false
    proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
   }
}
}

And, no matter what Gradle version I use, or what buildToolsVersion, I get the same error.

I'm also not using gradlew, but I've tried it and it still didn't work.

This is what I use to do the build: SET ANDROID_HOME=C:/android-sdk-win&&SET PATH=C:/gradle-5.6.4/bin;%PATH%&&SET JAVA_HOME=C:/Program Files (x86)/Java/jdk1.8.0_20&&cd C:/Android/Dev/G_BaseBuild&&gradle clean

When I try to do the initial 'gradle clean' I get this:

FAILURE: Build failed with an exception.

What went wrong: A problem occurred configuring project ':app'.

Failed to notify project evaluation listener.

I can't get: classpath 'com.android.tools.build:gradle:3.4.1'

to work, much less anything newer.

But if I use: classpath 'com.android.tools.build:gradle:3.3.3'

It builds fine.

What should I try to get this to be able to do a successful 'gradle clean' with possibly a newer Android Gradle Plugin?

Thanks!!

****** UPDATE ******

I was looking at everything Android Studio was using when it would do a Clean, and Build, and I saw that it was using it's own JRE/JDK at C:\Program Files\Android\Android Studio\jre So I updated everything to try to duplicate what it was using and it worked!!

But, what I found out is that Android Studio seems to be using a version of the OpenJdk.

Using Android Studio, I had it switch to using the same JDK I was using and it started getting the same bytecode errors.

So I downloaded and installed an OpenJdk, pointed to it in my build and then I could do a 'gradle clean' and 'gradle assembleDebug' without any issues!

Thanks!
