If a RedisConnectionFactory is detected the system will now export
metrics to redis every 5s (initializr.metrics.rateMillis). Metric
names are prefixed with <id>.<hex>. where <id> defaults to the
application name (initializr.metrics.id) and <hex> is unique. An
aggregator app can then pick up the values and (for instance)
continue counters across restarts.
The code is meant to be easier to upgrade Spring Boot 1.3
There are 2 beans that we can simply remove when we upgrade to 1.3.
Meanwhile, the app will run with 1.3 (or 1.2) for testing if you
uncomment the @ExportMetricWriter.
Make sure that the title and description of each capability is
configurable and expose that information in the meta-data.
This typically allows to customize the header of each capability in the
UI and the description in help usage such as the optimized text output
for command line clients.

Spring Boot 1.3 snapshots had changed the id of the Gradle plugin from
spring-boot to org.springframework.boot.spring-boot. This change has
since been reverted.
This commit updates the Initializr to revert back to using the old id,
spring-boot. Some custom Spring Boot 1.3 logic remains: the dependency
management plugin is not applied to a Boot 1.3 project as Spring Boot
1.3 applies it automatically.
BOM id and version range can now be shared at the group level. If no
specific attribute is set, the defaults from the group are inherited.
Closes gh-105
Add explicit support for Bill Of Materials. When a dependency defines a
bom ID, the related bom is added to the project. The metadata are
validated on startup to make sure a dependency does not refer to an
unknown bom entry.
Closes gh-99
Add support for the dependency management plugin for Gradle so that BOMs
can be added to the project if needed.
Also, the Gradle plugin as from Spring Boot 1.3 has changed and this
commit brings a transparent support for it.
Closes gh-98
InitializrMetadataBuilder can now merge a number of resources into a
single meta-data instance. A new `/metadata/service` endpoint is now
available and exposes the service meta-data of the current instance.
Combining those two, it is now possible to bootstrap an instance without
a single line of configuration; instead, the meta-data are built from the
content of a json document describing the service meta-data. This
document can be fetched remotely (via the new endpoint) or loaded from
a local file.
Each capability, including the InitializrConfiguration has now a `merge`
method with a "last wins" strategy. For collections, only unknown
elements are added.
Closes gh-88
Provide a more flexible meta-data contract and clearly separate the
service configuration from the options used to generate a project.
The meta-data now defines a fixed set of core service capabilities. Each
capability has an id, a type, a description and a 'content'. The
following capability types are supported:
* text: single value
* single-select: a list of values, one value should be chosen
* hierarchical-multi-select: values of values, many values can be chosen
* action: a specific single-select that defines the action to invoke
An extension can now build its own meta-data instance more easily.
Closes gh-87
Add an extra group with the databases that Boot supports out-of-the-box.
This is a first step of a better user experience when someone selects
the `data-jpa` or `jdbc` starter as it requires a Database to operate and
none is provided by default.
Closes gh-84
Add an extra 'scope' attribute to any dependency (defaults to 'compile').
Update maven and gradle build templates to support compile, runtime,
provided and test dependencies. Also, dependencies are now sorted
according to their ids.
Closes gh-83
Previously, specifying a baseDir with a value holding a sub-directory
would fail as only the first directory got created. This commit allows
baseDir to hold a sub-directory as well (e.g. something like 'foo/bar').
Fixes gh-81
Previously, if a user choose 'SpringBoot' or 'Spring' as the name of the
project, the service will generate a `SpringBootApplication` or
`SpringApplication` respectively. Both of which leads to a compilation
failure since those names are already used in the current context.
The generation of the application name based on the project's name have
been moved to InitializrMetadata and two new properties have been
introduced:
* env.fallbackApplicationName defines the name of the application if the
one that was generated was invalid for some reasons
* env.invalidApplicationNames defines a list of application names that
should flagged as invalid. When the current candidate is equal to one of
them, the fallback should be used instead
These properties have default values that prevent such issue to happen
by default.
Fixes gh-79
