(Sheesh. I apologize for trying to do something else concurrently. I
meant no disrespect. I'm on board now and the changes are up there
again. I'm awaiting NiFi to recycle now.)

So once deployed my UI also does not display anything. So I dug deeper
into your tika-1.0.1.jar file and found inside the processors folder your
TikaProcess.class along with 2 innerclasses called $1 and $2. I don't
have
this one though in my nars. So I tried to look around for your Pom
plugin.
Would you try rebuilding and updating your pom plugin to the current dev
doc recommendation (drop the incubator).

Joseph,
You're right. Somehow, /nifi-tika-1.0.1.jar/ is not found among the
myriad JARs under /META-INF/bundle//d-dependen//c//ies/ in the NAR. I
thought I'd seen it in there, but I had not looked hard enough. I'll
have
to revisit another (working) /pom.xml/ to see how that's stuffed into
it
(mysterious since all the other dependencies got in).
Yes, I had once found a later version of the /nifi-nar-plugin/ and
tried
it (because I tend to go with the latest tools for things like this),
but
without success so I went back to this one, the /1.0.1-incubating/
plug-in,
which is the one we started using at the beginning (about 18 months
ago)
and have always used.
Thanks very much for the second pair of eyes. I will insist upon
checking for this in my up-coming post, etc.

Can you share the content of
your /src/main/resources/META-INF/services/org.apache.nifi.proces
sor.Processor
file?
You also have this entry in some pom's which I dont have in my NAR
projects.

This
is a very perplexing problem because it's so simple. I'm happy to
make
available /pom.xml/ files and/or the NAR.

I've built a NAR containing a custom processor that loads in NiFi,

the

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]

Loaded NAR file: /home/russ/dev/nifi/nifi-1.1.1

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.Pro
cessor/
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.Pr
ocessor/)
`-- 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.
