==== Plugins, tasks and extension classes are abstract

Most public classes for plugins, tasks and extensions have been made abstract.
This was done to make it easier to remove boilerplate from Gradle's implementation.

Plugins that are affected by this change should make their classes abstract as well.

// Ignoring character classes p.numRunes is always less than the length of the regexp.
// Character classes can make it much larger: each \pL adds 1292 runes.
// 128 MB is enough for 32M runes, which is over 26k \pL instances.
// Note that repetitions do not make copies of the rune slices,
// so \pL{1000} is only one rune slice, not 1000.
// We could keep a cache of character classes we've seen,

    Mocking sophisticated classes like `OkHttpClient` is fragile and you
    shouldn’t do it. But if that’s how you want to live your life we won’t stand
    in your way!


## Version 3.0.1

_2016-01-14_

 *  Rollback OSGi support. This was causing library jars to include more classes
    than expected, which interfered with Gradle builds.


## Version 3.0.0

 * The internal `org.gradle.util` package is no longer imported by default.
+
Ideally you shouldn't use classes from this package, but, as a quick fix, you can add explicit imports to your build scripts for those classes.
 * The `gradlePluginPortal()` repository <<#rel5.0:gradle_plugin_portal_metadata,no longer looks for JARs without a POM by default>>.

   * <p>The {@code factory}-generated and {@code map} classes determine the multimap iteration
   * order. They also specify the behavior of the {@code equals}, {@code hashCode}, and {@code

| `Iterable<File>`*
| An iterable of input files and directories that represent a Java compile classpath. This allows the task to ignore irrelevant changes that do not affect the API of the classes in classpath. See also <<#sec:task_input_using_classpath_annotations,Using the classpath annotations>>.

The following kinds of changes to the classpath will be ignored:

* Changes to the path of jar or top level directories.
