Previously, the launch script used which to determine the availability
of start-stop-daemon. which isn’t available by default on all OSs.
For example, it’s not available by default on CentOS 5.
This commit updates the launch script to use type when determining if
start-stop-daemon is available. This improves the portability of the
script and makes the use of type consistent throughout the script.

Previously, the launch script would wait for the pid file to exist
before continuing. This didn’t work 100% of the time as it left a
window where the file had been created but the PID had not been written
to it that could result in an incorrect report of the app failing to
start.
This commit updates the script to wait for the file to have a size
greater than zero before continuing. This ensures that the pid has
been written to the file before the pid is read from the file and used
to check that the process is running.
Closes gh-4923
Update exit code support to allow the ExitCodeGenerator interface to
be placed on an Exception. Any uncaught exception implementing the
interface and returning a non `0` status will now trigger a System.exit
with the code.
Fixes gh-4803
Ensure that Collections.isEmpty() is used to check if there are no
elements in a collections. This is more explicit and can be faster than
calling .size().
Closes gh-4783
Exiting with 0 when cd fails is likely to be incorrectly interpreted
as success so we should exit with a non-zero value. Ideally, the init
script status action would exit with 4 but, at the point when
the cd is performed, we don’t even know if we’re running as an init
script. Exiting with 1 seems to be a reasonable compromise as it’s
fine for the non init-script case as well as being correct for all
init script actions other than status.

Allow users to easily opt-opt of using the start-stop-daemon in the

Replace all new-line characters in multi-line pom descriptions before
inserting into the launcher script. Prior to this commit the shell would
attempt to execut the extra lines, for example:
<description>
A multi-line pom description that could do something terrible:
rm -r foo

Some libraries like aspectj are using findResource to see the raw
bytecode of a class. It will even call findResource for every method of
every class of beans that are post processed. This can be significant
performance hit on startup when LaunchedURLClassLoader and there are a
lot of nested jars.
See gh-3640
Fixes gh-4557
There’s a race condition in start-stop-daemon when --make-pidfile and
--background are used together [1]. This race condition can lead to the
command returning before the PID file has been created. The missing PID
file then causes the launch script to incorrectly report that the
service failed to start.
This commit updates the launch script to wait for up to 10 seconds for
the PID file to be created when start-stop-daemon is used to launch the
app.

Update the launch script so that the PID file is not longer removed at

The HUP signal was being used to stop the service and for some reason,

The Maven POM does all the dependency resolutions for the
spring-boot-antlib project. Delegating this task to Ivy, which is
buried deep in the Antrun/Antunit part of the build, makes any kind
of proxy configuration much more complex.
The ivysettings.xml already has the local M2 repository configured,
but because the folder "repository" is missing, the artifacts, already
downloaded by Maven cannot be resolved from this location.
The Spring and Maven Central repositories should be removed from the
ivysettings.xml files in order to force all resolves to be done through
the local M2 repository. The POM of joda-time version 2.8.1 has an
optional dependency to joda-convert 1.2, which lets the Ivy resolve
process fail, because this version of the joda-convert library was
not resolved by any of the Maven POMs. It seems as if Ivy does not
respect the optional scope, defined in the joda-time POM.
Pass proxy settings to the forked process to make the Gradle distribution download work
Create a gradle.properties file for each Gradle integration test and writes the forking
process' proxy settings as systemProp.http(s).Host/Port to the properties file.
This configures the external process with the right proxy settings to let it download
the Gradle distribution via the HTTP proxy server.
Added a hint for Windows users to get the core.autocrlf setting right
When the core.autocrlf setting under Windows is set to false for example
All files are not converted regarding their EOL characters to the
Windows format with CRLF at a line's end. There is a checkstyle
validation that checks that all files have the system's line endings
and in some test-cases the value from the system property "line.ending"
is used to check test output. So without the conversion, those checks
are going to fail, resulting in build errors.

Previously, the meta-data annotation processor was taking the first
setter that match the property name it has to handle. Contrary to
getters that are enforced by a return type (no argument), multiple
setter candidates may exist.
If a property's type got narrowed over time, the original setter may
have been marked as Deprecated. As the annotation processor takes the
first setter that matches based on the name only, it may pick up the
deprecated one and therefore mark the property as being (wrongly)
deprecatede in the meta-data.
It turns out that checking for the actual type of the setter parameter
brought a side effect: some primitive properties may use the primitive
or the Wrapper counter part. This commit not only look at the proper
setter based on the type but also fallback on the wrapper (or) primitive
if necessary.
Closes gh-4338
By default, start-stop-daemon will chdir to the root directory before
starting the process. This prevents an application.properties file that
sits alongside the jar from being found.
This commit updates the call to start-stop-daemon to use --chdir to
set the working directory to that of the jar that’s being launched.
Closes gh-4281
Update the "INIT INFO section" of `launch.script` to include
`initInfoProvides`, `initInfoShortDescription` and `initInfoDescription`
property substitutions.
The Maven plugin has been updated to populate substitutions with
`${project.artifactId}`, `${project.name}` and `${project.description}`.
Fixes gh-4245
Flip the default value of `addResources` for both the Maven and Gradle
plugins. This effectively turns off static resources reloading and, more
importantly, the pruning of duplicate resources from the target
directory.
As devetools is our mainstram solution for such feature, the documantion
has been updated to reflect that.
Closes gh-4227
The init script spec [1] describes a number of requirements with which
our launch.script did not comply. This commit makes the following
corrections:
- Add support for force-reload which should be implemented by all
init scripts
- Don't fail restart if the service is already stopped or not running
- Consider stop to be successful if the service is already stopped
- Exit with 1 if stop fails (indicating a generic or unspecified error)
rather than 3 (unimplemented feature)
- Report a status of 1 if app is not running but the pid file exists
- Report a status of 3 if the app is not running (no pid file)

Previously, the launch script would always use a file named
<appname>.log to capture the application's console output. This commit
adds a variable, LOG_FILENAME, for specifying the file name defaulting
to <appname>.log.

This commit adds a dedicated property to specify the active profiles to
use when running an application via the Maven plugin. This works also
on the command line using the `run.profiles` system property and is
consistently applied whether the process is forked or not.

Previously, JarFileArchive would always unpack any entries marked for
unpacking to ${java.io.tmpdir}/spring-boot-libs. This could cause
problems if multiple Spring Boot applications were running on the same
host:
- If the apps are run as different users the first application would
create the spring-boot-libs directory and the second and subsequent
applications may not have write permissions to that directory
- Multiple apps may overwrite each others unpacked libs. At best this
will mean one copy of a jar is overwritten with another identical
copy. At worst the jars may have different contents so that some of
the contents of the original jar disappear unexpectedly.
This commit updates JarFileArchive to use an application-specific
location when unpacking libs. A directory beneath ${java.io.tmpdir} is
still used but it's now named <jar-file-name>-spring-boot-libs-<uuid>.
A loop, limited to 1000 attempts, is used to avoid problems caused by
the uuid clashing.

The recommended usage for the java executable is:

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.
