This commit adds a pullPolicy option to the configuration of the Maven
plugin spring-boot:build-image goal and the Gradle plugin bootBuildImage
task. The new option gives users control over pulling the builder image
and run image from a remote image registry to the local Docker daemon.

Previously, the Maven plugin integration tests used a settings.xml file
that defined https://repo.spring.io/snapshot as a repository. This
allowed them to resolve snapshots of the plugin's Spring Framework
dependencies but it had the unfortunate side-effect of also allowing
them to resolve snapshots of other Spring Boot modules from Artifactory
rather than using those currently being built.
This commit replaces the repositories in settings.xml with a Gradle
task that resolves the necessary dependencies and populates a local
repository with the dependencies' jars and pom files. This is achieved
using a ComponentMetadataRule that creates a custom variant of each
dependency that includes its pom file, inspired by the example in
gradle/gradle/#11449. A configuration that extends the
runtimeClasspath configuration and select the custom variant via its
attribute is then used to resolve the jars and pom files of the runtime
classpath such that they can then be used to populate the local
repository.
Closes gh-22828
Prior to this commit, an entry in the environment map provided to the
build plugin image building goal or task that had a null value would
result in a failure with a message that was difficult to diagnose.
This commit treats env map entries with a null value as an empty
entry to prevent the failure and also make it easier to provide an
explicit empty entry in the Maven XML.
Fixes gh-22703
This adds build caching and build scans.
The changes required disabling scans when using the maven invoker
plugin in order to not cause duplicate build scans when invoking other
maven builds. There is also an empty `.mvn` folder in the
spring-boot-starters project to prevent duplicate build scans as well
since there is no way to pass properties to the maven-javadoc-plugin.
The checkstyle plugin was causing a cache miss with the
`propertyExpansion` because it contains an absolute path. The absolute
path is now ignored and instead the files are added as inputs to the
checkstyle plugin. This only enables the local build cache. The remote
cache is not yet enabled.
On my local machine:
./mvnw clean install build times go from about 30 minutes to about 10 minutes.
./mvnw clean install -Pfull build times go from about 60 minutes to about 13 minutes.

This commit adds a check to the support code for the Gradle plugin
bootBuildImage task to ensure that the jar file that will be passed
to a builder is readable and has a valid directory. This prevents a
situation where the jar file cannot be read because it is prepended
with a launch script, and the builder does not receive any files to
process.
Notes have also been added to the Gradle plugin documentation to warn
against using a bootJar launchScript configuration and bootBuildImage
together, as well as caveats about launchScript that match the Maven
plugin documentation.
Fixes gh-22223
