Hmmm... It's rare that I debug NiFi code. And it's also rare that I
debug my own in that context since the NiFi test runner allows me to
fend off most surprises via my JUnit tests.
I think back in 2016, I was debugging a start-up problem involving NiFi
start-up and incompatibility with the Java Flight Recorder. As I recall,
I downloaded the relevant NiFi code sources matching the version of NiFi
I was debugging remotely. I remember ultimately making a slight (and
only temporary) change to NiFi start-up that fixed the problem. At that
point I must have been building my own copy to have seen it fixed.. It
had to do with the order in which NiFi was getting command-line
arguments making it so the JFR wasn't running. I'd have to dig back to
figure out what I was doing, but it's probably not too relevant to what
you need to do.
What do you need to see in this?

Correct. Primarily the nifi-web-api module and AccessResource class.
For starters.

Darren,
This is just Apache NiFi code out of NARs you want to step through or
is it yours? You haven't stripped debug information or anything, right?

Thanks for the info. I did set things up this way.
IntelliJ does connect to the nifi jvm and nifi runs and works but
intellij isnt breaking on code it should.
I did set the module where the code/classes are located (in the
remote connection dialog) and i see the exception im tracking print
on the console output but intellij never breaks.
Is there an extra step needed? Generate sources?
For future it would be nice if there was a maven goal for debug.
Much appreciated!

Darren,
I was out this morning and didn't see your plea until I got in just
now. Here's a step by step I wrote up for both IntelliJ IDEA and
Eclipse (I'm more an IntelliJ guy). It also covers using an IP tunnel.

Hi
Is it possible to run Nifi from inside IntelliJ with debugging
such that I can hit the app from my browser and trigger breakpoints?
If anyone has done this can you please share any info?
Thanks in advance!
