Loading code using command line SCM

Setting up an automated build environment using jbe and it's going well
except for the following.

The tools used to run the build (compilers, linkers etc) are stored in
the jazz repository in their own 'tools' component.

I had assumed that, before attempting to build using the JBE, on each
build machine that I setup, I'd able to login and run the equivalent of
a CVS or SVN checkout to get the latest tools from Jazz.

After logging in using the builders userid like so

scm login -r https://host:9443/jazz -u builder -P password -n WS

I then tried using the scm command line tool, something like

scm load tools -r WS

This works fine

I can also rerun this command any number of times using different
directories like so:

scm load tools -r WS --dir fred
scm load tools -r WS --dir bill
scm load tools -r WS --dir harry

All of the above commands work, and I end up having 4 copies of the
'tools' component on the system.


Now, if I go to another system, logging in and trying the same thing, I
get the following:

scm load tools -r WS
Problem running 'load':
Can not load into a subdirectory of an existing workspace.

scm load tools -r WS --dir fred
Problem running 'load':
Can not load into a subdirectory of an existing workspace.

scm load tools -r WS --dir .\fred
Problem running 'load':
Can not load into a subdirectory of an existing workspace.

scm load tools -r WS --dir c:\tmp
Problem running 'load':
Invalid repository URI: NSBUILD

What do these errors mean ?
