Do we have a policy for minimum Maven version for plugins?

[Dennis Lundberg <de...@apache.org>]

Hi,

Where do we currently stand when it comes to the minimum version of
Maven required by our plugins? Can a version 3.x Apache Maven plugin
require something newer than Maven 3.0?

The reason I ask is this
https://issues.apache.org/jira/browse/MSHARED-936
which has the consequence that all plugins using maven-filtering will need
to bump their Maven prerequisite, if I understand correctly.

Thanks Anders,

I found the page you mentioned at
https://maven.apache.org/developers/compatibility-plan.html

I've read that and also the technical details wiki page at
https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=155749857

The issue in question updates to Maven 3.1.0 dependencies so it can switch
to Eclipse Aether, which is one of the explicitly mentioned reasons in the
docs. I'll go ahead and process that issue.

There's been some discussion regarding this lately and my take is that
we've settled on that requiring Maven 3.1.0 is ok for plugins. In the same
discussion I *think* we settled on that a Java 8 requirement is ok.
What I don't think we all agreed on is if it's ok to bump the requirements
without a real code need, or if there needs to be a need before we bump. So
it's up to each dev to decide when working on a plugin.

There should even be a (draft) page outlining this. Don't have the URL at
hands right now though but it's in the list archive.
