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.

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.

Use dependencies instead of copies under 'lib' for assemblies
This is one step to get rid of org.aspectj:org.eclipse.jdt.core and
org.aspectj:asm-renamed in the 'lib' directory.
AspectJ tools + weaver uber JAR builds now use dependencies in the POM
in order to deal with creating binary + source assemblies. They no
longer rely on manually updated copies under 'lib'. Details:
- Binaries are copied via 'dependencySets' in the assembly descriptor.
- Sources are unzipped via Maven Dependency Plugin before including
them into the source uber JAR via assembly descriptor.
- NEW: This also includes ASM-renamed sources which so far were
ignored. It is a positive side-effect from the fact that for
ASM-renamed Maven Shade automatically creates a source JAR.
- Maven Ant Run is no longer used for unzipping binary + source JARs.
- While working in parallel with JDT Core and AspectJ it is now much
easier to produce up to date artifacts, e.g. for consumption by
AJDT, because it does not matter anymore if we forget to run the
build in module 'lib' in order to update the JDT Core copy.
Status quo:
- Folder lib/asm is no longer used and will be removed in a subsequent
commit.
- Folder lib/jdtcore-aj is no longer used by the Maven build, but
still referenced in a few UNIX shell scripts and Ant build files.
TODO: Find out if those are still actively used. If yes, refactor
them to look for the file in the local Mavven repository. Otherwise,
delete the referencing files and also lib/jdtcore-aj.

Remove module 'run-all-junit-tests' from root POM -> speed up the build
This module must be a relic from a test runner module once existing
during the Ant build era, but transferred and kept alive in the Maven
build. Actually, it almost doubles build time by running virtually all
tests in all modules again when doing 'mvn test' from the project root.
For now I only removed the module from the root POM, leaving behind
comments there, in the module POM and in the now @Deprecated class
RunTheseBeforeYouCommitTests.

Set maven-assembly-plugin version 3.1.1 explicitly for each POM module
Background: There are CI tests failing because the version is not taken
from the parent POM, even if set in the 'pluginManagement' section.
Instead, it is resolved via the Maven Super POM, e.g. 2.2-beta-5, see:
https://maven.apache.org/ref/3.6.3/maven-model-builder/super-pom.html
That assembly plugin version in turn requires plexus-archiver
1.0-alpha-12. The latter cannot be downloaded from Maven Central,
leading to the problems seen during builds.
