Mechanism to reinstall (editable) dependencies to trigger metadata re-build

• Poetry version: 1.2.1
• Python version: 3.8.10
• OS version and name: Ubuntu 21.04

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

When developing a project distributed over many repos that is connected by entrypoint plugins, consider that repo B depends on repo A, and thus contains:

repo-a = { path = "../repo-a/", develop = true }

Sometimes I need to change some entrypoints in repo-a.

For poetry to pick up the changes, I run poetry update repo-a (of course it can't otherwise know).

Unfortunately, it won't update entrypoints, so repo-b still sees the old ones (according to importlib_metadata, which I use to collect them).

The only workaround I know of is to:

• comment out the dependency
• run poetry update
• comment in the dependency
• run poetry update

Which causes a lot of useless package removal and re-installations, but in the end repo-a is registered correctly.

I am not sure whether this should be a feature request or a bug, but chose bug because to me this is "unexpected behavior".

I expect poetry to pick up these changes for local dependencies when I ask to update, even if nothing else about the dependency changed. The fact that it is "blind" to them violates the purpose of having a local dependency (with develop = True) - making it as painless as possible to simultaneously work on multiple related repositories.

Start with the poetry update handling for local dependencies declared with develop = true, and examine how entrypoint metadata is exposed through importlib_metadata. Done means updating a local dependency can rebuild or refresh its metadata without requiring the dependency to be removed and reinstalled.
