poetry remove crashes when removing a package from a legacy dependency group (PEP 735) containing include-group #10586
Description
Description
When attempting to remove a package from a dependency group that is defined using the PEP 735 format, the poetry remove command crashes and throws AttributeError: 'InlineTable' object has no attribute 'split' if nested group is used (the groups's dependency list contains { include-group = "..."} ), which is supported for Poetry 2.2.1: Including dependencies from other groups.
Analysis
The root cause appears to be in the implementation of the remove command. When processing a dependency group defined under the legacy [dependency-groups] key, the code iterates through a list that can contain mixed types (package strings and include-group tables). The command's logic does not filter out the non-string table objects before passing them to Dependency.create_from_pep_508, which expects a string.
Workarounds
May use the poetry style of nested poetry group:
[tool.poetry.group.test.dependencies]
pytest = "^8.0.0"
[tool.poetry.group.lint.dependencies]
ruff = "^0.11"
[tool.poetry.group.dev]
include-groups = [
"test",
"lint",
