Have you considered using a tool like Apache Maven to handle dependency
management for you? It's pretty uncommon these days to manually compile
your code. Another option is using ant+ivy.
If you are repackaging JARs, you may have run into a case where the jars
are sealed (we've started doing this in Accumulo a while back). The
error sounds like it's telling you the checksum for the Manifest file in
a JAR is invalid. This means that either the checksum was replaced or
you altered the Manifest file itself (and it now has a new checksum).
This one is in your camp to figure out..

Hi,
I am just starting to work with Accumulo, and I originally started testing with
the minicluster, but now, I have stood up a standalone (single server) Accumulo
instance.
I think that I got that working, but I would like to try the SimpleIngestClient
example from the minicluster with my new Accumulo instance.
So, I've been trying to compile the code for SimpleIngestClient that was in the
minicluster. There were a lot of JARs that I had to add to the classpath, but
i finally got the application to compile, but when I tried to run it, after
adding some more JARs to the classpath, I think I am stuck.
The error I am getting is shown below.

Does anyone know what might be causing that exception, and also how I can get
around it?
Thanks,
