Update SpringApplication to run by default in 'headless' mode. This
prevents the AWT system from creating a Java icon (for example in the
OSX dock).
Also update builds to run tests in 'headless' mode.
This appears to be a significant improvement in performance
(checking for the existence of init.grooy is cheap, but compiling
it is expensive).
I'm going to say this fixes gh-212.
Replace references to 'files' throughout the code-base with 'sources'
following the rename of `FileOptions` to `SourceOptions`.
Also cleanup ResourceUtils a little
We check for existence of the sources and (as before) resolve multiple
resources on the classpath if a path is not a File. In addition supports
Spring pseudo-URL prefixes as well as normal URLs as source locations.
In addition sources can now be specified as a directory (searched
recursively by default), or a resource pattern (e.g. app/**/*.groovy).
Fixes gh-207
The grab command downloads the dependencies of one or more Groovy
scripts to ./repository. This commit ensures that those previously
downloaded dependencies can be used by a subsequent invocation of the
run command.
The location and behaviour of the local cache is unaffected by this
change. If the dependencies in ./repository do not exist in the local
cache, Aether will "download" them from ./repository and store them in
the local cache.
Fixes#191
Previously, Aether's configuration was largely hard-coded making it
impossible to configure a mirror, provide credentials for accessing
a repository, etc.
This commit adds support for configuring Aether via Maven's
settings.xml file. The support is optional and must be enabled by
grabbing spring-boot-maven-settings in an init script. The Aether
instance that's used when running the application will then be
configured using settings.xml. The settings file is expected to be
found in ${user.home}/.m2/settings.xml.
The configuration of the following items is currently supported:
- Offline
- Proxies
- Mirrors
- Server authentication
- Local repository location
If the support is not enabled, settings.xml does not exist, or
settings.xml does not configure certain things then sensible defaults
are applied.
Previously, a transform was used to add @GrabResolver annotations
during compilation that added the Spring milestone and snapshot
repositories. This functionality is now handled by
RepositoryConfigurationFactory so the transform is no longer required.
Users can declare or Command, OptionHandler classes in an init script
or they can use a DSL, e.g.
command("foo") { args -> println "Do stuff with ${args} array" }
or
command("foo") {
options { option "bar", "Help text for bar option" ithOptionArg() ofType Integer }
run { options -> println "Do stuff with ${options.valueOf('bar')}" }
}
InitCommand runs on creation of SpringCli so it can search for additional
Commands in updated classpath. Also added as interactive command in Shell
session.
Change SpringCli so that running without arguments no longer jumps into
the embedded REPL shell. This restores the ability to obtain quick usage
help by simply typing `spring` from the command prompt.
Windows users or developers that prefer the embedded shell can still
launch it using `spring shell`.
Change OptionHandler to support '-cp' instead of '--cp'. This update
to the original fix (045088e8b) renders `help` output correctly and
should prevent potential issues if a `-p` command is added in the future.
Fixes gh-178
Main user-facing interface is still Counter/GaugeService but the
back end behind that has more options. The Default*Services write
metrics to a MetricWriter and there are some variants of that, and
also variants of MetricReader (basic read-only actions).
MetricRepository is now a combination of MetricReader, MetricWriter
and some more methods that make it a bit more repository like.
There is also a MultiMetricReader and a MultiMetricRepository for
the common case where metrics are stored in related (often open
ended) groups. Examples would be complex metrics like histograms
and "rich" metrics with averages and statistics attached (which
are both closed) and "field counters" which count the occurrences
of values of a particular named field or slot in an incoming message
(e.g. counting Twitter hastags, open ended).
In memory and redis implementations are provided for the repositories.
Generally speaking the in memory repository should be used as a
local buffer and then scheduled "exports" can be executed to copy
metric values accross to a remote repository for aggregation.
There is an Exporter interface to support this and a few implementations
dealing with different strategies for storing the results (singly or
grouped).
Codahale metrics are also supported through the MetricWriter interface.
Currently implemented through a naming convention (since Codahale has
a fixed object model this makes sense): metrics beginning with "histogram"
are Histograms, "timer" for Timers, "meter" for Meters etc.
Support for message driven metric consumption and production are provided
through a MetricWriterMessageHandler and a MessageChannelMetricWriter.
No support yet for pagination in the repositories, or for HATEOAS style
HTTP endpoints.
User can add (a single) beans{} DSL declaration (see GroovyBeanDefinitionReader
in Spring 4 for more detail) anywhere at the top level of an application source
file. It will be compiled to a closure and fed in to the application context
through a GroovyBeanDefinitionReader. Cool!
The example spring-boot-cli/samples/beans.groovy runs in an integration test
and passes (see SampleIntegrationTests).
It's super useful to get a reference to the current SpringCli
instance in the CommandFactory. Potentially implementations can
react to the properties of the Cli, or wrap it into something
more complex.
...supports the likely implementation of the REPL use
case that @jbrisbin has been working on.
Previously, the default classpath was empty. Now, in the absence of the
user providing a classpath via the -cp option, the default classpath
will be ".". If the user does specify a classpath, the classpath that's
used will be exactly what they have specified, i.e. "." will no longer
be on the classpath unless specified by the user.
The app sample integration test has been updated to verify that "." is
only the classpath by default.
Fixes#115
The JreProxySelector is used it to adjust the repositories
as they are added to the GrapeEngine. It looks at standard
System proeprties like http.proxyHost and http.proxyPort
and in addition consults standard JRE Authenticator features
for credentials (falling back to System properties
http.proxyUser and http.proxyPassword).
Fixes gh-136
Aether apparently doesn't use the java.net.* APIs for
TCP connections so it doesn't notice when a user sets
-Dhttp.Proxy*. To fix it is painful, and leads me to
suspect that actually we might want to parse a
settings.xml at some point (however unpalatable that
is).
For now I have added a Proxy to all RemoteRepository
instances that we create in the CLI if the user
has set -Dhttp.proxyHost (and/or -Dhttps.proxyHost for
a secure repository).
TODO: authentication. Is there a standard way to specify
that globally via system properties.
TODO: maybe use per-repository settings if provided
(e.g. in settings.xml).
The autoconfiguration transformations (and loads of grabs
of spring-boot snapshots) were making the grab command
tests run really slowly. Snapshots are particularly bad.
Fixed by adding a --autoconfigure=false option to the
compiler configuration and using it in that test.
Previously, run --local could be used to collect a script's
dependencies in ./repository. However, with this mechanism it wasn't
possible to collect the dependencies without running the application.
This commit adds a new command, grab, that can be used to collect
a script's dependencies in ./repository without having to run it.
run is configured with ./repository as a location in which it can find
its dependencies so that the previously collected dependencies
can be used when subsequently running the app.
As part of this work RunCommand and TestCommand have been refactored
to use common code for their common options:
--no-guess-imports
--no-guess-dependencies
--classpath
Previously, the declaration and handling of the options was duplicated
in the two classes. GrabCommand also has these three options and uses
the same common code.
Previously, the automatic addition of the group and version to a
@Grab annotation based on the module name would only work on standard
import statements. This commit adds support for this functionality
on wildcard imports, static imports and wildcard static imports.
All of the following are now supported:
@Grab('spring-core')
import org.springframework.util.Assert
@Grab('spring-core')
import org.springframework.util.*
@Grab('spring-core')
import static org.springframework.util.Assert.isTrue
@Grab('spring-core')
import static org.springframework.util.Assert.*
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.
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.
@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".

Rework classloading for launched applications so that CLI classes and
dependencies are not visible. This change allows many of the previous
hacks and workarounds to be removed.
With the exception of the 'org.springframework.boot.groovy' package
and 'groovy-all' all user required depndencies are now pulled in
via @Grab annotations.
The updated classloading algorithm has enabled the following changes:
- AetherGrapeEngine is now back in the cli project and the
spring-boot-cli-grape project has been removed. The AetherGrapeEngine
has also been simplified.
- The TestCommand now launches a TestRunner (similar in design to the
SpringApplicationRunner) and report test failures directly using
the junit TextListener. Adding custom 'testers' source to the users
project is no longer required. The previous 'double compile' for
tests has also been removed.
- Utility classes have been removed in favor of using versions from
spring-core.
- The CLI jar is now packaged using the 'boot-loader' rather than using
the maven shade plugin.
This commit also applied minor polish refactoring to a number of
classes.
