Previously, the CLI relied on Aether using the session's mirror
selector and authentication selector to customize the configured
repositories. These selectors are only used to configure what Aether
calls recessive repositories (repositories discovered when resolving
an artifact), rather than the explicitly configured repositories that
are typically used.

This commit updates AetherGrapeEngine to apply mirror and
authentication configuration to every added repository, bringing its
behaviour for these two settings into line with what it already does
for proxy configuration.

Fixes #1354

* Windows: allow absolute file paths without file:/// prefix
* All: only add nested archives (not directories), so loader.path=lib/*
behaves the same as -classpath=lib/* (except for adding zip files)

Fixes gh-1352

The ExplodedArchive would erroneously always attempt to filter
its contents (and thereby shield them from a classloader that wrapped
it) even if they haven't been explicitly provided.

* cleaning-up-maven-plugin-dependencies:
  Delete duplicate version numbers of Maven plugins

The Maven plugin version numbers are defined in the pluginManagement
of the spring-boot-dependencies pom.xml. Consequently, they can be
deleted in the spring-boot-starter-parent pom.xml to avoid version
conflicts and duplicated version management.

Fixes gh-1380

Use ant-run to clean spring-boot-samples when `clean` is invoked on
the main project.

Fix DefaultCounterService.reset to call the reset method of the
underlying MetricWriter.

Fixes gh-1391

Update StarterDependenciesIntegrationTests to only consider starter
folders that contain POM files.

Fixes gh-1395

Conflicts:
	spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/orm/jpa/JpaProperties.java

Update the the PathMatchingResourcePatternResolver used in the
MessageSourceAutoConfiguration condition to deal with the fact
that `classpath*:` patterns do not work with URLClassLoaders when
the pattern doesn't include a folder.

The ExtendedPathMatchingResourcePatternResolver works by searching
all classpath URLs when the `findAllClassPathResources` method is
called with an empty location.

Fixes gh-1378

Fixes gh-1393

The loading is via a marker interface SpringBootAstTransformation
to avoid clashing with other services registered as org.groovy.*

Fixes gh-1392

Closes #1387

Relax the generic signature on EntityManagerFactoryBuilder.properties
so that any object type can be added.

Fixed gh-1376

Update RelaxedDataBinder to support property aliases and change
DataSourceBuilder to use them.

Fixes gh-1384

Rename Banner.write to Banner.printBanner for consistency with the
now deprecated SpringApplication.printBanner method.

  Support programmatic banners via setter
