I am on Ubuntu 20.04 using ROS 2 Foxy. I have installed colcon using:

sudo apt install python3-colcon-common-extensions

It works fine, but I get desktop notifications when, for example, a build fails. I find the notifications extremely annoying. How can I disable them for colcon? I can't find an option to do that anywhere, and I don't want to disable notifications entirely.

Please see the recommendation from this ticket: https://github.com/colcon/colcon-noti...

Since the desktop_notification event handler is provided by a specific extension it is possible to blacklist that specific extension using an environment variable:

COLCON_EXTENSION_BLACKLIST=colcon_core.event_handler.desktop_notification

That's perfect. Thanks.

A quick update to Dirk's excellent answer:

Sometime between his answer and now the environment variable was renamed to COLCON_EXTENSION_BLOCKLIST so the proper incantation now is:

COLCON_EXTENSION_BLOCKLIST=colcon_core.event_handler.desktop_notification
