gh-actions: Windows buildout fails on z3c.relationfield

mauritsvanrees commented 2 years ago

This error first occurred after commit 3a1040920e37ff28ebd06188f45bedc54741ac3d three days ago, but that should really have no influence: it replaces a checkout of plone.namedfile with a new version. The error is:

While:
  Installing instance.
  Getting distribution for 'z3c.relationfield==0.9.0'.

An internal error occurred due to a bug in either zc.buildout or in a
recipe being used:

The action runs after this commit all fail with the same error: Windows tries to move the z3c.relationfield egg to a place where this egg already exists, which makes no sense. Any idea?

I suppose I could make a release of that package in the hopes that this magically fixes the build. In the past three years no real code changes were done. The package could use gh-actions instead of Travis, and run tests on Python 3.9 and 3.10. Volunteers are welcome.

@mauritsvanrees I cleared the github caches and now the build passed. I don't understand the root cause yet, so maybe it will happen again.

Weird. Thanks!
