Pellet hasn't updated it's dependency on jena in several years. You'll
need to use the jena jars that match Pellet.
jena 2.10.1 looks to be your best bet.

if if the issue below is fixed, there maybe others so the best course is
to clone from github and build it with an updated dependency

Hi,
I'm trying to use Jena 2.13.0 with Pellet; I downloaded the latest Apache
Jena library 2.13.0.
Then, I downloaded the jar file pellet-jena-2.3.2 and imported the JENA
libraries.
But i get this exception:
