Ken,
does your fat jar include all the module META-INF/services SPI files
from the module jars? (And concatenate those with the same name?)
GeoTools loads many SPI providers, including those for functions and
data stores. If some of these entries are omitted from the fat jar,
those SPI providers will not be found. In particular, the gt-main copy
of META-INF/services/org.opengis.filter.expression.Function will be
needed in the fat jar for org.geotools.filter.LengthFunction to be
available via SPI and found by the filter factory. As can be seen from
the stack trace below, this function is used to set length restrictions
when reading shapefiles.
Kind regards,
Ben.

Hi, I'm trying to use the following:
- gt-shapefile v19.0
- SBT 1.0.3
- SBT Assembly v0.14.5
- Scala v2.11.12
If I compile and run via SBT, everything works fine. However if I assemble
a fat jar, this error pops out:

i've searched and tried seem to be outdated and don't work for me. Is there
anything I can do about this error?
