Jeremiah, How are you depending on org.apache.nifi:nifi-processor-utilities? Is it a compile dependency, or a provided dependency?
It should be "compile" and not "provided" Dan Bress Software Engineer ONYX Consulting Services ________________________________________ From: Adams, Jeremiah <[email protected]> Sent: Thursday, June 25, 2015 4:41 PM To: dev Subject: Problem with Custom Processor I am having some problems getting a custom processor to run in 0.1.0-snapshot.

I've followed the doc her: https://cwiki.apache.org/confluence/display/NIFI/Maven+Projects+for+Custom+Processors Everything builds. I've dropped the resulting *.nar and *.jar file in /lib and restarted the server. I get the error above. Can anyone get me pointed in the right direction?
