docker-java 3.0 was causing a variety of problems and it appears that
we can get things working with Docker Java 2.2.x and Jackson 2.6.
Previously, the launch script integration tests ran happily on OS X and
on Bamboo’s Linux instances. With the upgrade to docker-java 3.0 that
is no longer the case with the default DockerClientConfig failing on
Bamboo as the default DOCKER_CERT_PATH location does not exist.
This commit updates the client configuration so that it attempts to
build the configuration once in it default configuration and, if this
fails, it tries again without TLS verification. This skips the check
of DOCKER_CERT_PATH’s validity.
Previously, the launch script integration tests used Jackson 2.1 to
align with the requirements of docker-java 2.x. This stopped working
when we upgraded to Spring Framework 4.3 which requires Jackson 2.6+.
This commit updates the launch script integration tests to use
docker-java 3.0.0-RC1 which is compatible with Jackson 2.6.x. An added
benefit is that 3.0 also adds support for copying an archive to a
container, allowing the custom command that performs this function to
be removed.

When an application is run as an executable archive with nested jars,
the application's own classes need to be able to load classes from
within the nested jars. This means that the application's classes need
to be loaded by the same class loader as is used for the nested jars.
When an application is launched with java -jar the contents of the
jar are on the class path of the app class loader, which is the
parent of the LaunchedURLClassLoader that is used to load classes
from within the nested jars. If the root of the jar includes the
application's classes, they would be loaded by the app class loader
and, therefore, would not be able to load classes from within the
nested jars.
Previously, this problem was resolved by LaunchedURLClassLoader being
created with a copy of all of the app class laoder's URLs and by
using an unconventional delegation model that caused it to skip its
parent (the app class loader) and jump straight to its root class
loader. This ensured that the LaunchedURLClassLoader would load both
the application's own classes and those from within any nested jars.
Unfortunately, this unusual delegation model has proved to be
problematic. We have seen and worked around some problems with Java
Agents (see gh-4911 and gh-863), but there are others (see gh-4868)
that cannot be made to work with the current delegation model.
This commit reworks LaunchedURLClassLoader to use a conventional
delegate model with the app class loader as its parent. With this
change in place, the application's own classes need to be hidden
from the app class loader via some other means. This is now achieved
by packaging application classes in BOOT-INF/classes (and, for
symmetry, nested jars are now packaged in BOOT-INF/lib). Both the
JarLauncher and the PropertiesLauncher (which supports the executable
jar layout) have been updated to look for classes and nested jars in
these new locations.

Fixes gh-4868
Commit 5a1ee6eb added support for disabling use of start-stop-daemon
via a placeholder in the default launch script. Unfortunately, that
placeholder was subsequently broken in 81a47639.
This commit reinstates the placeholder and adds tests to verify that all
of the placeholders in the launch script can be replaced and that they
have the required default values. Furthermore, it also allows the use of
start-stop-daemon to be configured via USE_START_STOP_DAEMON in an
app’s .conf file. This allows the configuration to be changed after the
app has been built.

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.
Fixes gh-4367, fixes gh-3816
Add an `excludeDevtools` property to both the Maven and Gradle plugin
that removes `org.springframework.boot:spring-boot-devtools` (if
necessary) when repackaging the application.
Closes gh-3171
Update the samples and integration tests to use Java 8. There's no
specific reason to keep them on Java 6 and it helps keep Eclipse happy
if we upgrade.
Given that Spring Boot uses java config accross the board, a new `value`
attribute is now aliased to the existing `classes` attribute such that
one could write the following:
@SpringApplicationConfiguration(MyConfig.class)
public class MyTest {}
Closes gh-3635
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.
