Currently, the situation looks more like a Java 21 maintenance release
than directly a Java 22 release.

Document build profiles and properties in docs/developer/BUILD.md
In doing so, I also noticed a few things in need of improvement. So,
documenting the build also drive those enhancements, such as
- the new 'fast-build' profile skipping test compilation and execution
as well as documentation generation,
- an option to skip generating source assemblies,
- to skip unzipping source assemblies if javadoc generation for them
is to be skipped too,
- activating the 'create-docs' profile by property which is
true by default instead of using 'activeByDefault=true', because the
latter does not work reliably if other profiles are activated
manually according to a Maven bug that was closed as "won't fix",
- no longer generating separate javadocs for the 'runtime' module,
because that module is not deployed and the main artifacts recreate
Javadocs from scratch for all of their constituent sources anyway.

This is a bugfix release, reverting the essential parts of commit
f70aeb5e, because it causes AspectJ Maven integration tests using
javadoc to fail on JDK 8.

Upgrade Maven Shade Plugin to 3.2.4.MSHADE-252-391
Unfortunately, the issues fixed in the aspectj.dev fork are still not
available upstream (MSHADE-252 is merged, but unreleased, MSHADE-391 is
in review).
Also use Maven Javadoc Plugin version from parent POM.

Before, we used 1.9.7.BUILD-SNAPSHOT, which according to Andy Clement
was originally an intent across a group of Spring projects he was
involved in, to ensure that SNAPSHOTS were sorted alphabetically ahead
of MILESTONEs and ahead of RCs.

Other than Maven Deploy, Nexus Staging plugin cannot just be added to
the 'build/plugins' section of the parent POM once and (de-)activated
with a simple property like 'maven.deploy.skip' on a per-module basis.
See also https://issues.sonatype.org/browse/OSSRH-68966. Consequently,
we do not add it to the parent but separately to each module meant to be
published.

Create javadoc for all public artifacts, fix dependencies
Sonatype OSSRH repository rules require source and javadoc JARs in
order to create staging repositories for releases to be promoted to
Maven Central. So I added build steps to unzip the source JARs and then
create Javadocs for them.
FIXME: This configuration works with JDK 16, but throws errors on other
JDK versions, e.g. 14. It looks as if the Maven Javadoc plugin does not
do a particularly good job applying the plugin settings in a way making
it work with different JDK javadoc tool versions. I am saying that,
because when using the tool directly on the console, it works with basic
settings and the correct classpath.
In order to enable creating uber JARs via Maven Shade in the future, I
also added missing dependencies. Maven Assembly descriptors just assume
that all the necessary class files and sources already exist where it
copies them from. But several of the dependency modules were not
explicitly listed as such by the uber JAR modules. I fixed that.

Add information required by Maven Central to public artifact POMs
This is another step away from manual deployment towards Maven-triggered
deployment for both releases and snapshots. The 5 main POMs (matcher,
runtime, weaver, tools, installer) now contain information required by
Sonatype for Maven Central deployments according to:
https://central.sonatype.org/publish/requirements/
TODO:
- Add corresponding 'distributionManagement' section and necessary
release plugins for Sonatype OSS repositories to parent POM.
- Enable Maven to also use Install plugin in order to automatically
set release versions, commit to Git and tag releases, then upgrade
to a new snapshot afterwards.
- Make sure that Flatten Maven plugin does not strip off the required
tags we just added to the POMs. It looks as if the chosen
flattenMode=oss already retains the exact tags we need, only
slightly reformatting (hence "uglifying") the POM. But an ugly POM
does not block Maven Central deployments, as long as it is complete.
So it looks as if this to-do item is already done.

Prepare main artifacts to be deployed via Maven, step 2
This change affects the following modules:
- aspectjmatcher
- aspectjrt
- aspectjtools
- aspectjweaver
- installer
- asm-renamed
Set maven.deploy.skip=false in parent POM, i.e. Maven Deploy by default
will *not deploy anything. Only in the modules above, we change the
value to 'true' in order to deploy those artifacts.
This setting works for both snapshot repositories (GitHub Packages, soon
to be migrated to aspectj.dev in a separate PR) and release
repositories, i.e. in the future also for Maven Central.

Prepare main artifacts to be deployed via Maven, step 1
This change affects the following modules:
- aspectjmatcher
- aspectjrt
- aspectjtools
- aspectjweaver
- installer
They have in common that they all use Maven Assembly Plugin in order to
create some kind of uber JARs with constituent modules and/or libraries.
Except for the installer, they are all available on Maven Central today,
but I think it would not hurt to deploy the installer to there, too.
Changes made:
- Use Flatten Maven Plugin in order to create simple POMs with only
basic information and - most importantly - without dependencies.
- The new dependency-reduced POM (DRP) or "flattened POM" gets
attached to the build, i.e. it will be installed and deployed as a
replacement of the original POM.
- Attaching the DRP only works for 'jar' type modules, which is why I
changed the packaging type for each module from 'pom' to 'jar'.
- Deactivate generation of the default JAR for each module. This is
necessary now, since we have the 'jar' packaging type.
- Make sure that assembly descriptors using 'dependencySet' entries
have set option 'useProjectArtifact=false' in order to avoid
warnings about the non-existing main artifact.
TODO:
- Explore option to migrate from Maven Assembly to Maven Shade,
because it does not need descriptor files, can also generate source
JARs and can automatically create and attach a DRP which is less
fragmentary than the one created by Flatten Maven, basically the
original JAR minus the dependencies.
- If in the future we want to make sure to only deploy the modules
listed above, e.g. to Maven Central, if simply calling 'mvn deploy'
for the whole project, we could use 'maven.deploy.skip=true' in the
parent POM and override it by 'maven.deploy.skip=false' just in the
few modules which need to be deployed. See also:

Fix: make sure that source assemblies are attached to build
Previously I renamed the source assemblies from the uniform name
'sources' to something more individual like 'aspectjtools-sources', not
realising that the magic name 'sources' in combination with the default
configuration value 'appendAssemblyId=true' results in an artifact
classifier equal to the assembly ID, i.e. 'sources', which is exactly
what we need here, but not quite obvious. Therefore, I documented it
with comments in both the assemblies and the POMs.
