Cannot create a new distribution export from existing content, chicken and egg

[fredvd]

I have a project where I want to add my local configuration as demo/default content for the distribution. I just found out this is not possible (yet). in

plone.distribution/src/plone/distribution/cli/__init__.py

Line 36 in 9145dd0

distribution = get_current_distribution(site)

the distribution with which the site was created is being requested. But this is in my use case not known since I'm starting a new distribution. So I should first manually recreate my site example content. Meh.

I assume it is possible to add an extra parameter to the export-distribution command line tool where you can specify the distribution. I'll see if I have time to contribute a PR.

I've checked the cli and exporting code a bit more. An annotation is stored on the site root of any Plone site that has been created 'from' a distribution and that annotation is restored to a Distribution object and required as soon as en export is needed. I'm not sure what exactly is needed from the Distribution object.

I also wanted to export some example content from a "default" Classic-UI Plone Site into my (not yet installed) customer distribution. As a solution, I would add a --path parameter to the export script to define the output path manually in cli instead of automatically get it from an installed distribution.

@petschki The plone.distribution export is based on plone.exportimport. If you want to export content to a path instead of in the context of an installed distribution, there is an export script provided by plone.exportimport: https://github.com/plone/plone.exportimport/blob/main/setup.py#L93

(This issue is still valid, I'm just pointing to a workaround)
