To reproduce:

1. Open the project, attached by the user (BustedAndroidBuild.zip)
2. In the Player Settings -> Other Settings Minify section, set Debug to Proguard or Gradle (Experimental)
3. Build and Run project on an Android device
4. Observe that as soon as the build launches on the device, the errors show up and the application closes

Expected: the build works on the device

Reproduced in 2017.3.1f1, 2018.1.0f1
Couldn't test in 2018.2.0b1: the build fails with error "Could not find method implementation() for arguments [{name=MaxUnityPlugin, ext=aar}] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler."
Could not test in earlier versions: the build fails with error "Could not find method google() for arguments [] on repository container"

Tested on Samsung-SM-G950U (Galaxy S8)

The issue occurs in Development Version as well as Release version
