Velocity and Freemarker share some common properties so the base class for
configuring their properties makes some sense. Unfortunately the implementation
pulls in Spring MVC at runtime because of the signature of one method (that
would never be called). We can fix that in a number of ways, but the least
disruptive is probably to change the signature of that method and only refer
to the concrete template view resolver type if the method is called.

Add the servlet and context path along with the exception message to
the error logged in ErrorPageFilter.

See gh-1427

For some reason I thought that the DispatcherServlet default handler
would log all exceptions, so if we did it in the ErrorPageFilter it
would lead to duplicates. That appears not to be the case.

We can't easily solve the problem by not allowing Spring Security to
eagerly instantiate everything, but we can be defensive about data.sql
and make sure it is executed even if the listener isn't yet registered.

This reverts commit bbdfcd4f.

Fixes gh-1423

Fix DataSourceProperties getUsername() and getPassword() methods to
call getDriverClassName() rather than using `this.driverClassName` to
ensure than deduced driver classes can be used.

Fixes gh-1421

Update CONTRIBUTING.adoc with improved code formatter instructions.

Fixes gh-1271

Update ExtendedPathMatchingResourcePatternResolver to use similar
code as the fix for SPR-12095.

Fixes gh-1378

Fixes #1411

Previously, ProjectLibraries only considered a configuration's
direct file dependencies. This meant that a transitive file
dependency that should have been pulled in via a project dependency
was not included in the repackaged jar's lib directory.

ProjectLibraries has been updated to walk down the tree of project
dependencies and create libraries for any file dependencies that
are found.

Fixes gh-1368

Update `spring-boot-starter-data-rest` to remove duplicate jackson
dependencies.

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.

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.

Fixes gh-1395

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