So the failure is valid - it's coming from changes in geotools between 12.x and 13.x+; the SimpleFeatureTypeBuilder class had a bunch of set(...) methods added here: geotools/geotools@33e9de5#diff-69cbda95a5fcc79676d0c12b73dd3f21
the diff makes use of one of those methods here:
https://github.com/ngageoint/geowave/blob/GEOWAVE-468/extensions/formats/geotools-vector/src/main/java/mil/nga/giat/geowave/format/geotools/vector/retyping/date/DateFieldRetypingSource.java#L66

and the first profile uses 12.4 of geotools, so the method isn't found.

Now what to do about this; typically we have been looking to stick with N and N-1. 14.x isn't out yet. I looking at what got added in the commit above though, and what was supported in 12.x I don't see a super clean way to do this (since attributes is protected, and there's no accessor) - but I just glanced it it real quick.

Dropping 12.x support a bit early isn't out of the question - just want to get a double check and make sure there's not an easy way to maintain it. @rfecher

that is kinda annoying - I think there should be a much less elegant way to set an attribute descriptor in 12.x that will also work in 13+ (I think looping over the attributes and just adding the attribute descriptor with SimpleFeatureTypeBuilder.add() if its not the date field and adding the new descriptor if it is the date field). But they are close to releasing v14.0 so my vote is that we drop support for 12.x in our next minor release (0.8.9). We are releasing 0.8.8.1 on Monday with some bug fixes and Eric's other commit can make it into that but we'll hold off on this commit (so 0.8.8.1 will be the last one with geotoools 12.x support).

I actually had it at first where it would loop through the AttributeDescriptors of the initial type, re-add them if they weren't the ones marked to replace, and replace them if need be. It worked but I thought this solution was more concise.

I can switch back to that if it would be preferable to also maintain GeoTools 12.x support.

When convenient, I think it's ready to be merged. I squashed my changes into one commit, switched back to support GeoTools 12.x, and addressed the code comments. Thanks!
