+    //                  Will become a runtime dependency of the generated Maven pom.
+    //  * testCompile - Required during compilation or runtime of the test source set.

-// Dependency Management for Java Projects
-// ---------------------------------------
-//
-// By default, the shadow plugin is enabled to perform shading of commonly found dependencies.
-// Because of this it is important that dependencies are added to the correct configuration.
-// Dependencies should fall into one of these four configurations:
-//  * compile     - Required during compilation or runtime of the main source set.
-//                  This configuration represents all dependencies that much also be shaded away
-//                  otherwise the generated Maven pom will be missing this dependency.
-//  * shadow      - Required during compilation or runtime of the main source set.
-//                  Will become a runtime dependency of the generated Maven pom.
-//  * testCompile - Required during compilation or runtime of the test source set.
-//                  This must be shaded away in the shaded test jar.
-//  * shadowTest  - Required during compilation or runtime of the test source set.
-//                  TODO: Figure out whether this should be a test scope dependency
-//                  of the generated Maven pom.
-//
-// When creating a cross-project dependency between two Java projects, one should only rely on the shaded configurations.
-// This allows for compilation/test execution to occur against the final artifact that will be provided to users.
-// This is by done by referencing the "shadow" or "shadowTest" configuration as so:
-//   dependencies {
-//     shadow project(path: "other:java:project1", configuration: "shadow")
-//     shadowTest project(path: "other:java:project2", configuration: "shadowTest")
-//   }
-// This will ensure the correct set of transitive dependencies from those projects are correctly added to the
-// main and test source set runtimes.

> This is a best practice recommended by the Gradle documentation. It is expected to speed things up, and makes dependency management and testing slightly better.
> In terms of code, it is not much different, though some things that were previously implicit in the top-level groovy DSL will need to be made explicit in the plugin definition.
