svn external path on a versioned directory

Question

Say I have the following structure (on the same svn server, but different repos):

Repo:
A/
A/B/c.py

External Project:
C/D/
C/B/f.py

I want to set svn:externals on A/, like so:

^/../C/D A/D
^/../C/B A/B

My goal is to have the resulting structure look like this:

A/
A/D
A/B/c.py
A/B/f.py

After I do propset on A/ (and double check it with propget), I run "svn up A/". svn fetches C/D/ just fine, but when fetching C/B/, it says that B/ is locked. Is it possible to do this, or does svn not support mixing an external directory with a local svn directory?

Answer 1

Nope, not possible. See http://svnbook.red-bean.com/en/1.7/svn.advanced.externals.html where it says:

The relative target subdirectories of externals definitions must not already exist on your or other users' systems
