There is no option for this in the Jenkins SVN plugin. However, I was able to achieve this on Windows using the Junction Link directory - and you could do the same when installing * nix with a symlink.
In particular, I wrote down the Jenkins / myjob / workspace directory and did it
mklink /J junction_to_working_copy c:\my\real\working\copy
then in the Jenkins project Subversion setup (in the "Source Control" section) for the "Local module directory (optional)" field, which I entered:
junction_to_working_copy
It does a good trick
source share
