Adding forked repositories

[TheSven73]

In #9658 (comment), @seeker25 asked if our executor class can correctly handle forked repos with the same name. It currently cannot.

However, I can't seem to find a way to actually do this. The other Poetry layers don't seem let me (which is a good thing!)

click = {git = "https://github.com/TheSven73/click.git"}
click = "^8.1.7"

$ poetry lock
Cannot overwrite a value (at line 16, column 17)

clicker = {git = "https://github.com/TheSven73/click.git"}
click = "^8.1.7"

$ poetry lock

The dependency name for clicker does not match the actual package's name: click

@gustavgransbo @radoering can you think of a way to trigger a problem with a forked repo?

[radoering]

It should only be possible with different packages in subdirectories as in the example in #9658 (comment):

pkg_1 = {git = "git@github.com:foo/my_packages.git", subdirectory = "pkg_1"}
pkg_2 = {git = "git@github.com:bar/my_packages.git", subdirectory = "pkg_2"}

Thanks ! Using your example, poetry lock crashes. That doesn't sound like an executor problem, maybe there are issues elsewhere preventing this usecase?

[tool.poetry.dependencies]
python = "^3.10"
click1 = {git = "https://github.com/TheSven73/click.git", subdirectory = "click1"}
click2 = {git = "https://github.com/pallets/click.git", subdirectory = "click2"}

The subdirectory must be the base directory of the python project (the directory where the pyproject.toml is located). Thus, you need some sort of monorepo with several python projects inside.

[gustavgransbo]

In this repo, I triggered the error by changing the pyproject.toml to something
like this:

[tool.poetry]
name = "some_other_repo"
version = "0.1.0"
description = ""
authors = ["Jonathan Rayner <jonathan.j.rayner@gmail.com>"]
packages = [{ include = "some_other_repo"}]

[tool.poetry.dependencies]
python = "^3.10 <3.13"

pkg_1 = {git = "git@github.com:JonathanRayner/some_monorepo.git", subdirectory = "pkg_1" }
pkg_2 = {git = "git@github.com:gustavgransbo/some_monorepo.git", subdirectory = "pkg_2", tag="v2"}

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

Created a WIP #9723 feel free to have a look.
