[MWRAPPER-129][MWRAPPER-128] Drop legacy stuff, require Maven 3.6.3+

[cstamas]

Also refresh and reshuffle to not duplicate dependencies and versions. Tend to use properties for versions where there is 2+ of them, otherwise is just fluff.

The org.codehaus.plexus:plexus-io dependency seems that is not used.

[jorsol]

Why not 3.6.3? this PR is about dropping legacy stuff ;)

[cstamas]

Yeah, I did not want to change prerequisite, it was more to kill this antipattern to "compile against eons old" maven that prevents noticing what is being deprecated lately in APIs and Core... (and replaced eon old aether w/ maven-resolver)

[slawekjaranowski]

I'm still not sure about it ... when we depend on newer version we can have some issues in runtime which is not cover by ITs.
But from other side we have more information about depractions ...

The perfect way will be for me depends on the same version as in in prerequisites ... but we block using plugin for older Maven ....

So we need a compromise on it 😄

[slawekjaranowski]

but we should be consequential and put here 3.6.3 as we do in more of plugins now

[cstamas]

Yeah, but all plugin builds use at least two Maven version: 3.9.6 and ... usually 3.6.3. So what "issue in runtime" you expect? Okay, if test coverage is poor... but then we fix and improve coverage, and life goes on...

[slawekjaranowski]

Please also add to commit message and issue title, that we also require 3.6.3 to be clear in release notes

[cstamas]

Tomorrow will check is plexus-io really used or not....

[jorsol]

Tomorrow will check is plexus-io really used or not....

Maybe is used transitively, so never mind.

[cstamas]

Hm, removed it and it builds...

[cstamas]

Yes, is used:
