Russell, Not sure if this is a typo but have you noticed this?

At the top of /TikaProcessor.java/, I have, among other annotations, this: @Tags( { "tika" } ) I've tried a number of things to solve this, like making it the only NAR besides just the set NiFi 1.1.1 ships with, and wiping out all flows down to a blank canvas. I tried removing SNAPSHOT from its version. *I see this in **/logs/nifi-app.log/*: This is the only reference to it in any log, but it does make me think that it's loaded: 2017-03-28 15:24:20,226 INFO [main] org.apache.nifi.nar.NarClassLoaders Loaded NAR file: /home/russ/dev/nifi/nifi-1.1.1 /./work/nar/extensions/nifi-tika-1.0.1.nar-unpacked as class loader org.apache.nifi.nar.NarClassLoader[./work/nar/extensions/ nifi-tika-1.0.1.nar-unpacked] In /resources/META_INF/services/, /org.apache.nifi.processor.Processor/ contains: /com.imatsolutions.nifi.processor.TikaProcessor/ I have a separate, very large project with many custom processors all of which load fine (and I've used this one before. In fact, the only thing I've done is remove this long-working processor from a larger set.) This project is very small: nifi-tika +-- nar | +-- /nifi-tika-1.0.1.nar/ | `-- pom.xml (packaging is "nar") +-- pom.xml (packaging is "pom") `-- tika +-- pom.xml (packaging is "jar") +-- src (test, resources, etc. including /resources/META_INF/services/org.apache.nifi.p//rocessor.Processor/) `-- target `-- /tika-1.0.1.jar/ I'm not certain what else to try. My /pom.xml/ files produce a NAR. NiFi appears to dignify it as a NAR. I keep retracing all the steps, but cannot figure out what I've missed.
