Add DependencyConvergence checks to parent pom

[aldenquimby]

This fixes a dependency convergence issue introduced via 3ada8d8.

Any projects that currently depend on morfologik 2.1.0 and have maven-enforcer dependency convergence enabled need to add a morfologik-stemming entry in dependencyManagement to deal with the conflict.

I came across this when upgrading my languagetool dependency from 3.1 to 3.3 - see languagetool-org/languagetool#342 (comment) for additional context.

I added a dependency convergence check to the morfologik parent so that I could test this change by running mvn validate. I'm happy to remove that, or move it, if you don't want to enforce dependency convergence.

Thanks for pointing this out -- this is in fact a bug, the whole dependency is a mistake (don't know why it ended up there).

Could you rebase your patch on top of the removed dependency section (just add dependency convergence checks). Also, this plugin should run only in verify phase, no need to do it all the time.

@dweiss thanks for the quick response here. I rebased and moved to verify phase - anything else I should do for this?

[dweiss]

Nope, this looks good -- thanks!
