Summary

The pyproject.toml file:

[project]
name = "foo"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.13"
dependencies = [
    "itsdangerous>=2.2.0",
]

[dependency-groups]
foo = ["iniconfig"]
bar = ["blinker"]

[tool.uv]
default-groups = ["foo"]

1. --no-group can not be used with --no-default-groups

❯ uv tree --no-default-groups --no-group bar
error: the argument '--no-default-groups' cannot be used with '--no-group <NO_GROUP>'

Usage: uv tree --no-default-groups

Expected:
uv tree --no-default-groups --no-group bar should be equivalent to uv tree --no-group foo --no-group bar.

2. --no-default-groups has higher priority than --all-groups

❯ uv tree --all-groups --no-default-groups
Resolved 4 packages in 13ms
foo v0.1.0
└── itsdangerous v2.2.0

Expected:
uv tree --all-groups --no-default-groups should be equivalent to uv tree --no-group foo --group bar:

❯ uv tree --no-group foo --group bar
