Regex support for VersionGenerator

[xen0n]

This fixes #605, complete with test cases. Hopefully I didn't miss anything important (the XML part is automatically done by the mojo, right?); please review.

Thanks!

Haven't had a chance to run it up but it looks good.
Double points for adding tests :-)

Any other @simpligility/android-maven-plugins-core-committers want to chime in?

I also looked at it and I like it but currently I can't test this.

As I can see in the code the default behaviour will be triggered if you don't specify a pattern so it is a low risk to merge.

Btw thx for the tests +1

Any heads-up on this? Still I haven't found a way to completely implement the old behaviour with regexes. I'd rather not introduce flags or similar things, only for the sake of getting rid of old code...

So wdyt @simpligility/android-maven-plugins-core-committers .. pull this in and break old behaviour as part of a 4.2.0 release?

[william-ferguson-au]

Yep - merge it.

[Shusshu]

Merge this in :)
Btw it does not break old behaviour as it can still fallback to the old code...
