Cannot change resolution strategy of dependency configuration ':app:compile' after it has been resolved.

I've tried Gradle Configuration for JUnit Foundation in my android project and got such build issue

Cannot change resolution strategy of dependency configuration ':app:compile' after it has been resolved.

Steps to reproduce

• Android gradle plugin com.android.tools.build:gradle:4.0.1
• Gradle version 6.1.1
• Create an android project and do setup JUnit Foundation for Gradle Configuration.

I'm not a Gradle expert, by any standard. The most likely source of this failure is the ext section that attempts to acquire a reference to the JUnit Foundation artifact itself. What happens if you disable this section and hard-code the JAR path in the jvmArgs statement?

In a Maven project, the process of acquiring the path to the JUnit Foundation JAR is handled by the Maven dependency plugin. You can see this in the Maven example that precedes the Gradle example you pointed to. I found this post that may provide a different approach to the problem:

Here's another potential formulation: https://github.com/bmuschko/gradle-cargo-plugin/issues/63

I think I have a working formula for Android:

android {
    testOptions {
        unitTests.all {
            jvmArgs "-javaagent:${classpath.find { it.name.contains('junit-foundation') }.absolutePath}"
        }
    }
}

This is definitely successful in applying the transformations of the JUnit 4 classes by the JUnit Foundation agent.
