Unable to upload any sketch to ItsyBitsy nRF52840 using adafruit-nrfutil and arduino-cli

[ardnew]

Describe the bug
When trying to upload any sketch using the official arduino-cli, the adafruit-nrfutil upload utility fails to locate the generated DFU .zip package, and thus can't program the device.

Set up (please complete the following information)

• ItsyBitsy nRF52840, adafruit:nrf52 0.19.0, arduino-cli Version: 0.0.0-git Commit: 8759bf46

Error: Invalid value for "-pkg" / "--package": Path "/home/andrew/Development/arduino/sketchbook/bled/bled.adafruit.nrf52.itsybitsy52840.zip" does not exist.
Error during Upload: uploading error: exit status 2

To Reproduce
Steps to reproduce the behavior:

1. Install arduino-cli
2. Install Adafruit nRF52 core:

arduino-cli core update-index --additional-urls https://adafruit.github.io/arduino-board-index/package_adafruit_index.json
arduino-cli core install --additional-urls https://adafruit.github.io/arduino-board-index/package_adafruit_index.json adafruit:nrf52

3. Using any valid sketch, compile and upload using a non-default build path specified at command line:

arduino-cli compile --verbose --log-level trace --fqbn adafruit:nrf52:itsybitsy52840 --upload --port /dev/ttyACM1  --build-path /home/andrew/.tmp/arduino-build/bled --build-cache-path /home/andrew/.tmp/arduino-build.cache/bled  /home/andrew/Development/arduino/sketchbook/bled

Expected behavior
I expect the adafruit-nrfutil to locate the generated DFU .zip package and use it to program the device.

Screenshots
N/A

Additional context
This issue was also posted at arduino/arduino-cli#641 because I'm not really sure which project is responsible. There is a little more detail in diagnosing the issue in that thread.

If I manually upload using the utility template and provide the DFU .zip path explicitly, the programming works as expected:

adafruit-nrfutil --verbose dfu serial -pkg /home/andrew/.tmp/arduino-build/bled/bled.ino.zip -p /dev/ttyACM1 -b 115200 --singlebank

I have tried with arduino-cli 0.11.0 , seems like they fix the issue, it is worth to give it a try again.

arduino-cli Version: 0.11.0 Commit: 0296f4d

Tested with much simpler command that take the sketch folder as parameter (this is necessary for the output zip file is expanded correctly in the upload command). Note: if you have issue with arduino-cli cannot perform DTR, please update to master which add a few ms delay before reset into DFU #549 .

arduino-cli compile --fqbn adafruit:nrf52:feather52840:softdevice=s140v6,debug=l0 --upload --port /dev/ttyACM0 sketch_jul29a

Sketch uses 74116 bytes (9%) of program storage space. Maximum is 815104 bytes.
Global variables use 11996 bytes (5%) of dynamic memory, leaving 225572 bytes for local variables. Maximum is 237568 bytes.
