We are using the (great) custom build record root directory feature, to store build records on an external location, at /some-static-path/${ITEM_FULLNAME}/builds

So far so good.

But when we rename a helloWorld job (which has build records) to helloWorld.newname, the rename succeeds, but throws this exception in the browser:

Exception: failed to rename /some-static-path/helloWorld/builds to /some-static-path/helloWorld.newname/builds
Stacktrace:

It seems the main issue here is that the 'new' external location directory at /some-static-path/helloWorld.newname/builds does not yet exist. Is it possible to do a 'mkdir -p' to create this directory, before doing the renameTo?
