colcon build failed

[mockbot]

during installation at a fresh environment, I've noticed, that 'colcon build' failed with some errors...
assert verb_extensions, 'No verb extensions'

after some search I found this solution:

pip3 install pytest-rerunfailures

cd ~/DDS-Router
rm -rf src

mkdir src
vcs import src < ddsrouter.repos
colcon build

Bug or feature ? ;-)

Thank you for reporting this issue.
It is true it seems like a common known error when using colcon:
aws-robotics/aws-iot-bridge-example#2

This is most likely a bug (colcon bug).
We will add for future versions a requirements.txt so it can be executed in a virtual environment, or add this dependency to the installation guide.

However, python is only used in ddsrouter_yaml_validator and in some tests.
So, if you are not using such tool, you can use command colcon build --packages-skip ddsrouter_yaml_validator to build it without problem.
