poetry add --dev not installing as dev dependency for git dependencies

[GiancarloFusiello]

Hi @sdispater, poetry is a great tool that has been missing from the Python community for a long time. I wanted to point out this small bug that I hope should be an easy fix.

poetry add libero-schemas --git https://github.com/libero/schemas.git --dev

Installs the dependency and adds it to pyproject.toml:

[tool.poetry.dependencies]
lxml = "^4.3"

[tool.poetry.dev-dependencies]
libero-schemas = {git = "https://github.com/libero/schemas.git"}

However, in poetry.lock it appears to have installed as a main dependency rather than a dev dependency:

[[package]]
category = "main"
description = "Libero data model schemas"
name = "libero-schemas"
optional = false
python-versions = "*"
version = "0.0.1"

[package.source]
reference = "cebfb5fb66b3bd7b820e2cebf50f9cc471d5204c"
type = "git"
url = "https://github.com/libero/schemas.git"
[[package]]
category = "main"
description = "Powerful and Pythonic XML processing library combining libxml2/libxslt with the ElementTree API."
name = "lxml"
optional = false
python-versions = "*"
version = "4.3.0"

Also notice that a blank line is missing after [package.source] in poetry.lock.

Thanks, in advance and keep up the good work.

I've noticed the same issue, with no response from the developers... Is this related to #599 ?
