switch from 4.0.0-beta-4 to 3.17.0 - #1209

need to check/clarify Maven 3 plugin.xml generation = https://maven.apache.org/ref/3.9.16/maven-plugin-api/plugin.html
vs Maven 4 one = https://maven.apache.org/ref/4.0.0-rc-6/api/maven-api-plugin/plugin.html
see also apache/maven#13253

key difference is not only the new fields in Maven 4 plugin descriptor, but renamings:

• requiresDependencyResolution to dependencyResolution
• require* to new names
  see https://github.com/apache/maven/blob/master/api/maven-api-plugin/src/main/mdo/plugin.mdo#L211

this acts also dropping maven-script and old-Maven 2-style javadoc annotations

so it will be a braking change

I have checked plugin descriptor generated on a few plugins 3.x - build used plugin-tools 3.9.16 and 4.0.0-beta-3
looks the same

Of course we need check commits to cherry-pick, one I remember:

• Add validator for component requirements in generated plugin descriptor #1145
