With this commit the state of a component or subsystem becomes a first-class citizen in Boot's application health support. HealthIndicators now return a Health instance with status and some contextual details.
An aggregation strategy has been introduced to aggregate several Health instances into one final application Health instance. Out of the box OrderedHealthAggregator can be configured to allow different ordering or a custom HealthAggregator bean can be registered.
The prefix needs to be added before looking for keys. In addition
I rationalized the constructor and final fields (it didn't make
any sense for the prefix to be mutable).
Fixes gh-927
The PrefixMetricGroupExporter only really makes sesne if the writer
is aware of the groups, so it seemed better to use a new interface
than mix read/write.
ExecutableArchiveLauncher creates a ClassLoader that is used by the
Launcher to load an application’s classes. During the creation of this
ClassLoader URLs from another ClassLoader are copied over. This was
resulting in Java agents that are added to the system class loader
via the -javaagent launch option being available on both the system
class loader and the created class loader. Java agents are intended to
always be loaded by the system class loader. Making them available on
another class loader breaks this model.
This commit updates ExecutableArchiveLauncher so that it skips the URLs
of any Java agents (found by examining the JVM’s input arguments) when
copying URLs over to the new classloader, thereby ensuring that Java
agents are only ever loaded by the system class loader.

OnBeanCondition has some issues with FactoryBean object types where
the FactoryBean is not generic (i.e. you have to instantiate it to
get its object type). This is a known issue (see tests in
ConditionalOnMissingBeanTests), but we can provide some help for
library authors who know the type in advance. The approach we have
taken here is to check the BeanDefinition for an attribute called
"factoryBeanObjectType" (OnBeanCondition.FACTORY_BEAN_OBJECT_TYPE)
which, if it exists, can be used as a tie-breaker. Its value should
be a Class<?> instance.

Add a new maven project containing a versions.properties file and
an effective POM. Rework existing projects to use the versions
artifacts.

Previously spring-boot-dependency-tools used spring-boot-tools as its
parent. This meant that it inherited spring-boot-parents' dependency
management that we did not want to expose to applications. The
solution to this was to generate the effective pom and then filter
out any thing that did not appear in spring-boot-dependencies' pom.
This filtering had to unwanted side-effect of breaking bom imports:
the effective pom would contain the dependency management from the
imported bom, but this would be filtered out as the entries didn't
appear in spring-boot-dependencies' pom.
This commit updates spring-boot-dependency-tools to use
spring-boot-dependencies as its parent. This means that its effective
pom contains the desired dependency management and nothing more,
allowing the filtering logic to be removed.
The use of Spring Security's bom has been reinstated as it will now
work as intended and versions for its modules will be available in the
CLI and via the Gradle plugin.

- Remove dependency management for projects that Boot does not have a
runtime dependency upon
- Provide dependency management for all of Spring Batch’s modules
Since Flyway has bean properties (with getters and setters)
it can be used to bin directly to the Environment (instead of
copying all the properties into FlywayProperties).
Fixes gh-806
Add support for a new annotation, @GrabMetadata, that can be used
to provide the coordinates of one or more properties files, such as
the one published by Spring IO Platform, as a source of dependency
metadata. For example:
@GrabMetadata("com.example:metadata:1.0.0")
The referenced properties files must be in the format
group:module=version.
Limitations:
- Only a single @GrabMetadata annotation is supported
- The referenced properties file must be accessible in one of the
default repositories, i.e. it cannot be accessed in a repository
that's added using @GrabResolver
Closes#814
Previous to this commit, any groupId starting with one of the
configured exclude would be excluded as well. This potentially
leads to unintentional dependency filtering: for example the
GroupIdFilter with an exclusion of "org.springframework"
also removes "org.springframework.boot" dependencies.
Add MatchingGroupIdFilter that uses an exact match instead.
