Description

The API of the Command class was changed in Poetry v2: the set_poetry instance method on the class has been removed. I think this method is useful for plugins, the Multiproject in specific where a build process is triggered based on Python code in temporary directories.

Impact

By restoring the set_poetry, plugins like Multiproject will not have to rely on the internals of the Command instance. (see workarounds)

Workarounds

Current workaround is implemented, to support Poetry before and after v2.

if hasattr(self, "set_poetry"):
    self.set_poetry(project_poetry)
elif hasattr(self, "_poetry"):
    self._poetry = project_poetry
