Refactor spring-boot-loader to work directly with low level zip data
structures, removing the need to read every byte when the application
loads.
This change was initially driven by the desire to improve tab-completion
time when working with the Spring CLI tool. Local tests show CLI
startup time improving from ~0.7 to ~0.22 seconds.
Startup times for regular Spring Boot applications are also improved,
for example, the tomcat sample application now starts 0.5 seconds
faster.
If the server port is 0 it doesn't mean you don't want *any* container
because there might still be servlet context aware components in the
classpath. Better to try and stop the server from actually starting.
This change is a step in the right direction: it prevents the server
from starting in the start() method (even though for technical reasons
it may have already been started and stopped in initialize()).
N.B. Tomcat at least uses port=0 as a signal it should pick a random
port. Pertty useful feature that we may want to capitalize on at some
point (on the other hand having our own port scanner would be useful
generally too).
Refactor bash shell completion to move the majority of the logic into
the Java code. This commit also removes the need for the '--' prefix on
every command.
Update the auto-configuration report to improve log formatting and to
separate the internal report data-structure from the JSON friendly
endpoint data-structure.
With the goal of making AetherGrapeEngine generally useful with Groovy,
this commit removes any Boot specifics from it. Specifically, there
is now only a single default repository: Maven Central. The
Boot-specific Spring milestone and snapshot repositories are now added
via @GrabResolver annotations that are added using an ASTTransformation.
As part of this change, AetherGrapeEngine has also been updated to store
its repositories using a LinkedHashSet, this ensures that the same
repository is not used more than once while maintaining their ordering.
Groovy's Grape allows a user to enable download reports using the
system property groovy.grape.report.downloads. This commit updates
AetherGrapeEngine to honour this property and produce a detailed
download report when the system property is set to true. In the
absence of the system property, or when it's set to a value other than
true, the existing summary report is still produced.

@GrabExclude can now be used to exclude certain transitive dependencies.
In Aether (Maven), exclusions are applied to an individual dependency
rather than being global. In Grape, exclusions are global.
AetherGrapeEngine adheres to the Grape convention by applying every
exclusion create by @GrabExclude to every dependency, effectively making
them global.
When a PropertySourcesPropertyValues is used to bind Environment
values to a bean (or the SpringApplication) it tries to resolve
placeholders eagerly in the Environment. Any that fail might not
actually be a problem for users (until validation is done it's
impossible to tell even whether that value was needed for the
ongoing binding or not).
Fixed by ignoring exceptions in the PropertySourcesPropertyValues
constructor.
Fixes gh-108
@GrabResolver can now be used to add a repository to the list that is
used for dependency resolution. Any repository that is added via the
annotation will then be available for the lifetime of the
AetherGrapeEngine instance. In reality, this equates to the lifetime
of the Boot application. This is in keeping with the documented default
behaviour [1]: "By default, the grape subsystem is shared globally, so
added resolvers will become available for any subsequent grab calls".

b19f6bb238 updated the CLI so that it should be launched using Spring
Boot Loader's JarLauncher, however the spring and spring.bat shell
scripts were not updated so they still launched the CLI by using
SpringCli as the main class. This led to a NoClassDefFoundError
as none of the dependencies in the jar's /lib directory could be
found.
This commit updates the two shells scripts to use JarLauncher as the
main class.
By default it is on, but you can switch it
off (`-P '!integration'`) to ignore integration tests
and get a faster build.
.travis.yml uses this feature so that it doesn't keep
failing on a timeout.
