Currently the default branch (hydro-devel) is hardcoded.

When trying to run pandoradep on pandora_visualization metapackage (branch: geotiff), I get an error:

Package conflict in pandora_geotiff_plugins
Info: 
{'repo': 'pandora_data_fusion', 'version': None, 'name': 'pandora_data_fusion_msgs'}
{'repo': 'pandora_data_fusion', 'version': 'geotiff_interfaces', 'name': 'pandora_data_fusion_msgs'}

That error was initially caught on an Jenkins job and then reproduced locally.

IMO a version different that None should always override a None version without the need of --force argument. Otherwise, we are going to use the --force argument constantly, which has no point.

When a command fails, pandoradep should return an exit code different than 0. For example when running pandoradep update and for some reason the command fails we should return 1, to mark the Jenkins build as failure.

The problem, in that particular case, is that in utils.py:116 the exception gets caught but not raised again. That might affect other commands, like when running pandoradep scan with a non existent directory as argument.

Originally this issue caught on an import Jenkins job. That job should have been marked as a failure.
