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.

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.

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

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.

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

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.

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

* pull1363:
  Support programmatic banners via setter

Introduce an easy way for the user to provide an custom programmatic
banner to the Application as alternative to the static banner.txt file,
without the need to override SpringApplication class.

Fixes gh-1363

* feature-configurable-ansioutput:
  Allow ANSI output to be configured by properties

Add AnsiOutputApplicationListener which configures AnsiOutput.enabled
based on a `spring.output.ansi.enabled` property.

Fixes gh-1243

Update MongoAutoConfiguration to be conditional on a missing
MongoDbFactory bean. The assumption is that if the user has declared
a MongoDbFactory they will either use it directly, or they will also
register a Mongo bean.

If the MongoDbFactory class cannot be found the existing Mongo
auto-configuration still applies. This ensures that users that do
not have Spring Data can still access a Mongo bean.

Fixes gh-1341

Fixes gh-1381

* spring-cloud-autoconfig:
  Add auto-configuration for Spring Cloud

Enable if all of the following are true:
- spring-cloud is on the classpath
- There is no Cloud bean present
  (usually done by extending AbstractCloudConfig)
- The "cloud" profile is active

Fixes gh-1302

Fixes gh-1369. Note that this is caused by the ErrorPageFilter, so
only a problem when deployed as a WAR.
