Description

In poetry 2.2.0, there is a problem when setting dependency groups to be optional.

Running poetry check on the example below fails with the error "The Poetry configuration is invalid: - tool.poetry.group.lint cannot be validated by any definition". This appears to be caused by this line in the JSON schema, which requries either dependencies or include-groups for everytool.poetry.group.

Workarounds

Uncommenting include-groups = [] in the example avoids the problem, but I'm not sure whether this would work if dependency-groups.lint had an include group.

install.python-poetry.org
