Will not work with QGIS 3.12 Bucuresti & ECLIPSE

[oddvardm]

I have configured QGIS & Eclipse with the following (all latest releases) plugins:

1. QGIS - Remote Debugger Plugin
2. Eclipse - PyDev Plugin
3. QGIS - Plugin Builder
4. QGIS - Plugin Reloader

I used the Plugin Builder to create a test plugin: MyTest. All loaded fine and works in QGIS.
The Problem start when I want to intercept the MyTest code in Eclipse.
I started the PyDev remote debugging server in Eclipse and it start up fine with port 5678 (default)
Started QGIS and connected to Eclipse/PyDev: 2020-06-14T20:50:57 INFO RemoteDebug : Debugging connection activated
In Eclipse I set breakpoint in my MyTest.py file.
Start (& reload) MyTest plugin i QGIS and no breakpoint is detected. MyTest plugin just starts up with no breakpoint stop. This is by the book https://www.sigterritoires.fr/index.php/en/how-to-set-up-eclipse-to-develop-qgis-scripts-or-plugins/ (you left out packages in python https://www.pydev.org/manual_adv_remote_debugger.html) and all seems to work fine. But it does not. Help needed :-/

After some more back and fourth the python console show this error when I connect:

(please create a ticket in the tracker to address this).

During handling of the above exception, another exception occurred:

Maybe an environment fault?

Changed PYTHONPATH to C:\OSGEO4W\bla..bla so no spaces in path. Now no errors in python console when I start remote debugger. But still not working.

I landed here thinking I had similar issues... here's what worked for me:

1. when adding your 'pydevd.py' folder path to QGIS's environment variable for PYTHONPATH, ensure you kick it off w/ a semicolon
2. when launching the RemoteDebug plugin, ensure the 'pydevd' path shown is to the folder containing pydeved.py, not pydevd.py itself.
