AttributeError when adding a dependency group when private repo present (Poetry 1.2.0a2)

I am on the latest Poetry version.
I have searched the issues of this repo and believe that this is not a duplicate.
If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

Not on latest, because I am on 1.2.0a2, which is newer than latest.

OS version and name: Linux Debian Bullseye in a container
Poetry version: 1.2.0a2
pyproject.toml file:

[tool.poetry]
name = "foobar"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.9"


[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

[[tool.poetry.source]]
name = "foo"
url = "https://foo.bar/simple/"

Issue

When using a private repo (i.e. having a [[tool.poetry.source]] section to pyproject.toml), and adding a group dependency (e.g. running poetry add --group test pytest, e.g. the feature added in #4260) for a group that does not yet exist in the pyproject.toml, poetry raises an exception.

# poetry add --group test pytest

Even though the example above has an invalid URL for the poetry source, this error happens even when the URL is valid and the necessary credentials to authenticate are present (e.g. a valid Google Artifact Repository repo), and regardless of whether the source is primary or secondary.

Also note that the dependency being added isn't even hosted inside the private repo. (In this case, trying to add pytest to a group called "test".)

Removing the [[tool.poetry.source]] section allows Poetry to properly add the dependency group and dependency.

The above pyproject.toml was generated using the following:

docker run -it --rm python:3.9-slim-bullseye bash

# Within the container:
pip install poetry==1.2.0a2
poetry init --name foobar -n
cat >> pyproject.toml <<EOF

[[tool.poetry.source]]
name = "foo"
url = "https://foo.bar/simple/"
EOF
# Then run poetry add --group test pytest to see the error

Full output when running with -vvv

# poetry -vvv add pytest --group test

Did some more investigation. This error only happens if the [[tool.poetry.source]] section is the last one in the file. If the order of the clauses is swapped around like so

[tool.poetry]
name = "foobar"
version = "0.1.0"
description = ""
authors = ["Your Name <you@example.com>"]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.9"

[[tool.poetry.source]]
name = "foo"
url = "https://foo.bar/simple/"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

(Notice that [build-system] and [[tool.poetry.source]] have swapped positions)

I noticed this because I was trying to create the above test case using a different command instead of the append poetry source add foo http://foo.bar/simple, which added the source before build-system.

I have the same error, also on version Poetry (version 1.2.0a2) but for me it occurs when references a local library ie somelib that has it's own pyproject.toml

Can be traced back to the update 1.2.0a2 here:

4b8384c#diff-8005012c00c842592c28b01560b1f9522146f351b70df58fadfec5c0245bd523

Unsure of the specifics, but it if you don't have a previously toml [tool.poetry.group] (or an tool.poetry.group.whatever.dependencies
)
this blows up:

poetry/poetry/console/commands/add.py

Lines 105 to 114 in 4b8384c

    
           if group == "default":

                   poetry_content["dependencies"] = table() 
        
               section = poetry_content["dependencies"]

                   poetry_content.value._insert_after("dependencies", "group", group_table)

An error in the same line happened with me when trying to add a new dev dependency to a project that was created with Poetry v1.1.11.

Replacing [tool.poetry.dev-dependencies] with [tool.poetry.group.dev.dependencies] solved the problem.

I can reproduce quickly this with

poetry init -q
echo "\n[tool.poetry.plugins]" >> pyproject.toml
poetry add --group dev pytest

on

poetry --version
Poetry (version 1.2.0a2)

produces

I confirm that moving the [build-system] section at the end solves the problem
