This reverts commit 4e36a079.

The order of the modules declared in pom.xml should not make any
difference given the other relationships that exist between projects,
however the CI build is ordering the projects incorrectly.

Try changing the order of the modules to see if the CI build can be
coaxed into ordering them correctly.

Update OnClassCondition to implement AutoConfigurationImportFilter so
that auto-configuration candidates can be filtered early. The
optimization helps to improve application startup time by reducing
the number of classes that are loaded.

See gh-7573

Add `AutoConfigurationImportFilter` strategy interface which can be used
to filter auto-configuration candidates before they are loaded.

See gh-7573

Optimize `AutoConfigurationSorter` by used properties generated by the
annotation processor whenever possible. The removes the need for each
candidate class to be ASM parsed just to access the order annotations.

See gh-7573

Add AutoConfigurationMetadata interface and a an internal loader that
allows easy access to data written by `spring-boot-configure-processor`.

See gh-7573

Add an annotation processor that generates properties files for certain
auto-configuration class annotations. Currently attribute values from
@AutoConfigureOrder, @AutoConfigureBefore, @AutoConfigureAfter and
@ConditionalOnClass annotations are stored.

The properties file will allow optimizations to be added in the
`spring-boot-autoconfigure` project. Primarily by removing the need
to ASM parse as many `.class` files.

See gh-7573

Optimize OnEnabledResourceChainCondition by removing the DataBinder.
Properties are now read directly from the Environment.

See gh-7573

Update `AutoConfigurationImportSelector` so that exclude properties
are loaded without invoking a `DataBinder`. This optimization helps
to improve application startup time.

See gh-7573

Update `JacksonJsonParser` to that the `ObjectMapper` is only
initialized on first use. This performance optimization helps with
startup times if nothing uses the parser.

Fixes gh-8074

Update `OnBeanCondition` to no longer call `ReflectionUtils` when
deducing the bean method return type. Since Spring Framework 4.2
the return type has been directly available from `MethodMetadata`.

See gh-7573

Update `OnClassCondition` to use its own `isPresent` rather than using
`ClassUtils.isPresent`. Using our own implementation saves a few cycles
since we never need to check for native types, and we don't support
nested class references specified in the non `$` notation.

See gh-7573

Remove the slightly unusual dependency from the root autoconfigure
pacakge to `condition`. Prior to this commit the link was required in
ordere to populate the `ConditionEvaluationReport`. We now introduce
a `AutoConfigurationImportListener` strategy that allows anyone to
listen for AutoConfigurationImportEvents. The listener implementation
is now used to update the ConditionEvaluationReport.

Fixes gh-8073

Rename EnableAutoConfigurationImportSelector to the more general
AutoConfigurationImportSelector since it's now used for more than
just the enable annotation.

The existing EnableAutoConfigurationImportSelector class remains in
a deprecated form so that it can be made package-private again in
Spring Boot 2.0.

Fixes gh-8072

Move PropertyPlaceholder and MessageSource auto-configuration from the
root package to the `context` subpackage.

Fixes gh-8071

See gh-8027

This commit deprecates the `exceptionIfInvalid` feature as we have now a
way to select the `@ConfigurationProperties` object to validate (i.e. add
`@Validated` on them).

Closes gh-8027

Previously, spring.profiles.include was only considered when it was
used in a configuration file. It was ignored in any other property
source.

This commit updates ConfigFileApplicationListener so that
spring.profiles.include can be used in any property source to add to
the profiles that have been declared active via
spring.profiles.active.

Previously, AspectJ would find META-INF/aop.xml almost as soon as
the jar was launched, and before LaunchedURLClassLoader had been
created. This meant that AspectJ would attempt to load aspects listed
in META-INF/aop.xml but that were package in BOOT-INF/classes and,
therefore, could not be loaded.

This commit updates the Repackager so that a META-INF/aop.xml file
is moved into BOOT-INF/classes. This ensures that it isn't visible
to the app class loader so it won't be loaded to early. It will
now be loaded by LaunchedURLClassLoader which can also load the
compiled aspects that aop.xml references.
