Use "return" instead of "exit" where possible, especially in
function definitions.
Also fixed the exit codes to match the LSB spec for some specific
conditions (fixes gh-3521).

Previously, manual meta-data were added to the existing set of entries
which could lead to duplicates if a manual entry is meant to complement
a property that is detected via the processor.
We now match the name and type of the item against the auto-detected
entries. If no match is found, we add the extra entry as we did before.
If a match is found we override the description, default value and
deprecation information.
Closes gh-3562
The annotation processor detects `@ConfigurationProperties` bean or
method definition and merges manual meta-data. The former step will fail
with a NPE if the annotation is not present on the classpath. This could
happen if the annotation processor is added to a module that is not
actually using Spring Boot.
We now have a defensive check that skips that steps but still attempts to
merge manual meta-data if present.
Closes gh-3720
When nested jars are being used, hasMoreElements requires opening a
connection for an entry in every nested jar. If that entry doesn't
exist, a FileNotFoundException is thrown to indicate that a particular
jar doesn't contain the requested entry. This exception is used to
indicate the lack of an entry and is then swallowed, i.e. its stack
trace is of no importance. This means that the performance of
hasMoreElements can be improved by switching on fast exceptions while
it's being called. When fast exceptions are switched on a general
purpose pre-initialized FileNotFoundException is thrown rather than
creating a new FileNotFoundException instance each time.
In certain situations, the use of fast exceptions as described above
can improve performance fairly significantly. The JRE's default SAAJ
implementation uses META-INF/services-based discovery for _every_
request that's handled by Spring Web Services. Each discovery attempt
results in hasMoreElements being called making its performance
critical to throughput.

DevTools look for a main thread named "main". The maven plugin is
actually using a different value and there is no real reason to. This
change fixes DevTools support as long as forking is enabled.
See gh-3315
8673250 updated the plugin so that the application plugin is no longer
applied by default. This exposed three problems:
1. bootRepackage may run before findMainClass has run, leaving it with
an unknown main class.
2. findMainClass may run before the classes have been built, making it
unable to find the main class by examining the class files
3. The project's mainClassName property was still being used as a
convention for the bootRun task's main property. If the application
plugin has not be applied, then this property does not exist.
The first problem has been addressed by configuring bootRepackage to
depend on findMainClass.
The second problem has been addressed by configuring the main source
set's output as an input of findMainClass, and configuring findMainClass
to depend on the tasks that build the output.
The third problem has been addressed by only using the mainClassName
property if it exists and its value is not null. We then fallback to
using the mainClassName property on the project's extra properties in
the same way.
See gh-2679
Previously, the Spring Boot Gradle plugin would always apply the
application plugin to a project. It then piggy-backed on the application
plugin’s mainClassName and applicationDefaultJvmArgs properties for the
configuration of the bootRun task.
This commit updates the Spring Boot Gradle plugin so that it no longer
applies the application plugin. If the user applies the application
plugin then its configuration will be used, but it’s a no longer
requirement.
Users who do not need the application plugin, but who were using the
mainClassName or applicationDefaultJvmArgs properties will need to
change their builds as a result of this change as those properties will
no longer exist. As before, the mainClassName can be configured on the
springBoot extension:
springBoot {
mainClassName 'com.example.YourApplication'
}
The applicationDefaultJvmArgs property can be used, but it must now be
declared with the project's ext block. For example:
ext {
applicationDefaultJvmArgs = [ '-Dcom.example.property=true' ]
}
Closes gh-2679
Add a new @DeprecatedConfigurationProperties annotation which can be
used by the `ConfigurationMetadataAnnotationProcessor` to generating
meta-data deprecated blocks.
Fixes gh-3543
Previously, an item could only have a 'deprecated' boolean flag to
indicate that the property is deprecated. It is desirable to provide an
additional description for the deprecation as well as the name of the
property to use instead.
The `deprecated` boolean flag is now supported. Instead, a `deprecated`
object can be specified with two optional attributes: `reason` to provide
an explanation for the deprecation and `replacement` to refer to the
property that should be used instead. If none of them is present, an
empty deprecation object should be set.
For backward compatibility, the `deprecated` field is still set.
Deprecation information can only set via manual meta-data.
Closes gh-3449
If a field is initialized via a factory method taking a single argument,
we can relatively safely consider that said argument is a good
representation of its default value. This is typically the case for
Charset or MimeType instances.
We now make sure to detect such use case (i.e. method argument with a
single argument).
Closes gh-3482
I think this is safe, judging by the integration tests, but I'm not
putting it in 1.2.x until we've had some feedback on it. The
integration tests actually had a bug that was masking this problem
because they were merging Properties from the whole classpath instead
of picking the first available resource (which is generally what
we do in Spring Boot applications for application.properties for
instance).
Fixes gh-3048
Liquibase has a `changeLog` property that is definitely used as a
`Resource` but cannot be defined as such as the original String value
should be kept against an API we don't control.
Update the tests also to make it more clear that if hints are added
against a property that is detected automatically, said property still
keeps all its auto-discovered capabilities.
Closes gh-3457
Add a new `spring-boot-configuration-metadata` module that provides an
API to manipulate Spring Boot configuration meta-data. Can read meta-data
from arbitrary locations, though the standard
`META-INF/spring-configuration-metadata.json` location must be preferred.
Closes gh-1970
When writing a jar, once an entry has been written it will never be
overwritten, i.e. the first write of a given entry will win. Previously,
when repackaging a jar, the existing contents were written followed by
any libraries. This caused a problem when repackaged a WAR file and
a library needed to be unpacked as the existing entry in WEB-INF/lib
would prevent the library with the UNPACK comment from being written.
This was addressed in f761916b by inverting the order so libraries
would take precedence over entries in the source jar.
It’s now become apparent that this change in the order causes a problem
for users who are obfuscating their code. The obfuscated code exists in
the source jar but is also provided to the repackager in its original
form as a library. When libraries take precedence, this means that the
code in its original form ends up in the repackaged war and the
obfuscation is lost.
This commit updates the repackager to write libraries that require
unpacking first. This allows the UNPACK comment to be written even if
there’s also a source entry for the library. Next, source entries are
written. This allows obfuscated source entries to take precedence over
any unobfuscated library equivalents. Lastly, standard libraries that
do not require unpacking are written into the repackaged archive.
Closes gh-3444
Previously, if the repackaged file was different from the main artifact
of the build, the maven plugin wrongly considered that it should attach
the file with a classifier.
The outputDirectory is honored properly now, regardless of the fact a
classifier is defined or not.
Fixes gh-3177
Make sure to fail the build with a proper compilation error message if
the user-defined meta-data are invalid. For now, this takes care of the
JSON format but other checks may be added in the future.
Closes gh-3329
Improve the "hints" section of the metadata so that each hint can provide
the reference to a value provider.
A value provider defines how a tool can discover the potential values of
a property based on the context. The provider is identifed by a name and
may have an arbitrary number of parameters.
Closes gh-3303
Create a new section in the meta-data called "hints" where users can
provide hints about a given property. The most basic use case for now
is to provide a list of values that a property can have. Each value may
have a description.
This sample JSON provides a basic example for a property called `foo.mode`
that exposes 3 values: "auto", "basic" and "advanced".
```
"hints": [
{
"id": "foo.mode",
"values": [
{
"value": "auto",
"description": "Some smart description."
},
{
"name": "basic"
},
{
"name": "advanced"
}
]
}
]
```
This information can be read by tools (such as IDE) and offer an
auto-completion with the list of values.
Closes gh-2054
Update the embedded launch script to include a `chkconfig` comment. This
solves the "Service doesn't support chkconfig" error when executing
the chkconfig command.

Update the launch script used in fully executable jars to:
- Include LSB-Header comments
- Source `.conf` files either next to the jar for additional script
configuration
Fixes gh-3243
Update the Maven and Gradle repackage tasks so that the embedded
startup script is no longer included by default. This change is
primarily due to the `cf` command line not currently accepting
the unusual jar format.

Do not rely on the packaging type to figure out what the extension of the
main artifact will be. So far, using `jar` and `war` packaging for `.jar`
and `.war` files worked by chance.
We know retrieve the actual extension as provided by Maven's
`ArtifactHandler`.

- Verify that isReady has been called
- When forking, use a random port for JMX
- Don’t wait for application termination as it introduces a race
condition and verifying that shutdown has been requested is
sufficient

SpringApplicationLifecycle provides basic lifecycle operations on the
current Spring Boot application (that is checking if the application has
fully started and gracefully terminate the app). It can be registered as
an MBean of the platform MBean server if a specific property is set.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.
Such change permits the maven plugin to integrate a classical integration
test scenario where the "start" goal is invoked during the
pre-integration phase and the "stop" goal during the post-integration
phase.
Closes gh-2525
Some of the features of the launch.script were not exposed for users
to be able to control at runtime. It now accepts things like
PID_FOLDER and LOG_FOLDER as environment variables, and also adopts
a clear naming convention where only the inputs are UPPER_CASE.
Previously, the CLI’s dependency management used proprietary Properties
file-based metadata to configure its dependency management. Since
spring-boot-gradle-plugin’s move to using the separate dependency
management plugin the CLI was the only user of this format.
This commit updates the CLI to use Maven boms to configure its
dependency management. By default it uses the spring-boot-dependencies
bom. This configuration can be augmented and overridden using the new
@DependencyManagementBom annotation which replaces @GrabMetadata.

This reverts commit b1c0a7cda4.
The plugin publishing process has moved to a new plugin-based approach
that brings with it some significant limitations:
- There's no staging to allow the promotion of good release builds
- There's no easy way to upload an existing artifact
- There's no control over the published pom.
The risk brought by these limitations, particularly the first, are
too great so we will no be publishing the Boot plugin to the Portal
until they're resolved.
Changing the plugin's ID was a breaking change that would require
users to do some work when they upgrade to Boot 1.3. The ID of the
plugin was changed purely so that it met the Portal's requirements.
Given that the plugin will not be published to the Portal for the
foreseaable future there's no need for us to inflict a breaking change
on people when there will be no benefit.

Update JarWriter to set the entry timestamp for nested jars. The
timestamp is set to same time as the first (non directory) entry in

SpringApplicationLifecycle provides lifecycle operations on the current
Spring Boot application. It can be registered as an MBean of the platform
MBean server if a specific property is set. Besides, the JMX name can
also be customized via a property in case more than one Spring Boot
application is started in the same process.
The Maven plugin uses that MBean to check that the application is ready
before ending the "start" phase. It uses it to trigger a proper shutdown
of the application during the "stop" phase.
If the process has to be forked, the platform MBean server is exposed on
a configurable port so that the maven plugin can connect to it.

The format is rather unusual.
The time is 16 bits: 5 bits for the hour, 6 bits for the minutes, and 5
bits for the seconds. 5 bits only allows 32 values (0-31) so the number
must be doubled, meaning that the time is only accurate to the nearest
two seconds. Also, the JDK rounds this down by subtracting one. The
doubling and rounding is performed by shifting one place to the left
and masking off the right-most bit respectively.
The date is 16 bits: 7 bits for the year, 4 bits for the month, and 5
bits for the day. The year is from 1980, i.e. the earliest date that
can be represented is 1980-01-01.
See http://mindprod.com/jgloss/zip.html for more details of the format.
