   Hello @kwin,
   
   Wow, resurrecting an old request !
   I rebased my change on branch "pre-reset-master" (see branch MNG-5909-oldmaster), then I cherry-picked in on top of the new master, fixing conflicts.
   
   It used to work on the initial version of this PR (almost 2 years ago), but I should take time to build & test this new version just to make sure it plays nicely with all the other changes in maven over the last 2 years. Maybe I'll find time during the weekend.
   
   Thanks for your interrest in this PR
   
   Loïc

>             Project: Maven
>          Issue Type: Improvement
>          Components: core
>    Affects Versions: 3.3.3

>            Priority: Major

> Currently each type of activation (os, jdk, file, property) can only be used once for activating a single profile.
> Therefore it is not possible to activate a profile in case two different files are existing, although since Maven 3.2.2 (MNG-4565) it is possible to combine multiple activations of different types.
> Multiple  {{file}} or {{property}} should therefore be supported to allow to express something like:
> Enable {{profileA}} in case both {{fileA}} and {{fileB}} do exists
> For {{jdk}} and {{os}} this is less relevant because all conditions are combined with AND.
