Cloned processor not loading

[Phil H <gi...@gmail.com>]

Hi there,

I have a working processor, Tom, which I cloned to form a second processor,
Jerry. All occurrences of Tom in the code/XML were replaced with Jerry in
the clone. The build process works for Jerry fine, as do the unit tests.
However when I load the Jerry into the nifi extensions directory, it fails
to present in the UI.

In the startup process in the logs, I see similar output for Tom & Jerry in
the early stages (abbreviated due to transcription)


INFO [main] o.a.n.n.NarClassLoaders Loaded NAR file:
nifi/work/nar/extensions/nifi-Tom-nar-0.1-nar-unpacked as class loader
o.a.n.n.NarClassLoader[./work/nar/extensions/nifi-Tom-nar-0.1-nar-unpacked]
INFO [main] o.a.n.n.NarClassLoaders Loaded NAR file:
nifi/work/nar/extensions/nifi-Jerry-nar-0.1-nar-unpacked as class loader
o.a.n.n.NarClassLoader[./work/nar/extensions/nifi-Jerry-nar-0.1-nar-unpacked]

However later there is some additional output for Tom (and other
processors) that is not present for Jerry:

   com.mycompany.nifi.Tom.Tom
      com.mycompany:nifi-Tom-nar:0.1 ||
./work/nar/extensions/nifi-Tom-nar-0.1-nar-unpacked

Not seeing any other errors or references to Jerry in any other log files.
What am I missing??

TIA,
Phil

Thank Mark,

I’d used sed to replace references to Tom with Jerry, but it fails on lines
lacking a newline char. Had to fix some of the XMLs for this reason. I did
look at those Processor files and wonder why they only had a comment in
them, but failed to check them against the originals from Tom

Cheers,
Phil

Phil,

Add the fully qualified class name of Jerry to the resources file in your
bundle:

{nifi-custom-bundle}/{nifi-custom-processors}/src/main/resources/META-INF/services/org.apache.nifi.processors.Processor

-Mark
