failure:
```
Could not resolve all files for configuration ':app:labDebugAndroidTestCompileClasspath'.

```kotlin
project.configurations.flatMap { conf ->
  // javadoc explicitly says conf.dependencies does not resolve the configuration
  conf.dependencies.map { dep ->
    // convert each dep to a string representation, like ":tguard" or "com.squareup.moshi:moshi:1.9.2"
  }
}
```

for the inner bit, that is
```kotlin
internal fun Dependency.toIdentifier(): String? = when (this) {
  is ProjectDependency -> {
    val identifier = dependencyProject.path
    if (isJavaPlatform()) // do something
    identifier
  }
  is ModuleDependency -> {
    // flat JAR/AAR files have no group.
    val identifier = if (group != null) "${group}:${name}" else name
    if (isJavaPlatform()) // do something
    identifier
  }
  is FileCollectionDependency -> {
    with(files.files) {
      // note that this will ignore any flat file dep beyond the first
      if (isNotEmpty()) first().name else null
    }
  }
  // Don't have enough information, so ignore it
  is SelfResolvingDependency -> null
  else -> throw GradleException("Unknown Dependency subtype: \n$this\n${javaClass.name}")
}
```

and finally
```kotlin
private fun Dependency.isJavaPlatform(): Boolean = when (this) {
  is ProjectDependency -> {
    dependencyProject.pluginManager.hasPlugin("java-platform")
  }
  is ModuleDependency -> {
    val category = attributes.getAttribute(Category.CATEGORY_ATTRIBUTE)
    category?.name == Category.REGULAR_PLATFORM || category?.name == Category.ENFORCED_PLATFORM
  }
  else -> throw GradleException("Unknown Dependency subtype: \n$this\n${javaClass.name}")
}
```

the :tguard project is a pure Kotlin-JVM project, no Android, and not java-library either. :app is a standard Android application project.
