**Note:** The `@Classpath` annotation was introduced in Gradle 3.2. To stay compatible with earlier Gradle versions, classpath properties should also be annotated with `@InputFiles`.

    }

    /**
     * Returns a filtered list of classpath elements. This method is invoked when the caller
     * requested that all dependencies are placed on the classpath, with no module-path element.
     *
     * @param scopeFilter a filter returning {@code true} for the artifact scopes to accept.
     * @param includeTestDir whether to include the test directory in the classpath elements.

====

Again, we're accessing a source set to get the relevant information, i.e. where the compiled test classes are — the `testClassesDirs` property — and what needs to be on the classpath when running them — `classpath`.

Since Gradle 1.0, runtime-scoped dependencies have been included in the Java compilation classpath, which has some drawbacks:

 * The compilation classpath is much larger than it needs to be, slowing down compilation.
 * The compilation classpath includes runtime-scoped files that do not impact compilation, resulting in unnecessary re-compilation when those files change.

Alternatively, you can adjust or remove classpath attributes in the `eclipse.classpath.file.whenMerged { }` block.
