gradle error - com.google.common.collect.ImmutableSet.toImmutableSet()Ljava/util/stream/Collector

Question

I've seen this mentioned a couple of times but yet to find a solution - after upgrading Gradle to 4.10.2 and the Android gradle plugin to 3.2.1, I'm having a lot of difficulties trying to build an Android app. It appears to be an incompatibility between plugins, specifically to do with the version of Guava in use. I believe it's one of the AWS plugins I'm using that's causing the issue but I'm using the latest version and I can't find any straightforward way of separating out the gradle script that needs the AWS plugin and the one that needs the Android plugin. Is there some way I can tell gradle which version of Guava to use when loading the AWS plugin? I've tried this but to no avail:

buildscript {
  repositories {
    mavenCentral()
    maven { url "https://plugins.gradle.org/m2/" }
  }
  dependencies {
    classpath "com.google.guava:guava:27.0.1-android"
    classpath "jp.classmethod.aws:gradle-aws-plugin:0.38"
  }
}

Just removing that last classpath entry fixes the problem, but I need it for the AWS tasks.

The strange thing is after I get that error and run gradle again I get a completely different error: "Could not initialize class com.android.build.gradle.internal.ide.ModelBuilder". This doesn't seem to get any google hits at all that are helpful.

FWIW the stack trace is:

 ...

This doesn't work either, for anyone wondering: ```configurations.classpath { resolutionStrategy { force 'com.google.guava:guava:27.0.1-android' } } ``` — Dylan Nicholson, Dec 03 '18 at 06:36

Finally got it working by adding this to the root build.gradle:

configurations.all {
  resolutionStrategy {
    force "com.google.guava:guava:23.0"
    force "commons-logging:commons-logging:1.2"
    force "commons-io:commons-io:2.4"
  }
}

After resolving the first conflict with guava there were 2 further ones, hence the necessary extra lines.

App seems to build and run fine, and the AWS commands are executing OK.
