Howdy,
I have created my own processor which I have been testing with
NiFi for a while now. This stuff used to work for me, now it doesn't. Today
nifi won't start. The nifi-app.log is below
The processor reads in an image type NITF and does a few things with it. I do
a:
$ mvn install
from ~/nifi-0.3.0/nifi-mitre-bundle/ which is where my software is. I then
$ cp
~/nifi-0.3.0/nifi-mitre-bundle/nifi-mitre-nar/target/nifi-mitre-nar-1.0-SNAPSHOT.nar
../lib/
When I start nifi the nifi-app.log shows the below exception with the bottom
line being
Caused by: java.lang.ClassNotFoundException: org.mitre.nifi.NiFiNITFReader
I looked in my lib/nifi-mitre-nar-1.0-SNAPSHOT.nar it contains

I see org/mitre/nifi/NiFiNITFReader.class in the jar file.
Any thoughts on what the problem is?
Thank you
