Our projects use build-parameters when performing the SVN checkout, so we can
specify the branch/tag from which to build.

For example, we have an SVN URL on a project like this:
http://subversion-server/repos/app/${SUBVERSION_PATH}/ProjectA

We provide SUBVERSION_PATH=trunk (as an example) when we run the build.

When the build runs, it ends with this error message:
moduleLocation: Remote
->http://subversion-server/repos/app/${SUBVERSION_PATH}/ProjectA
Failed to parse SVN repo URL. Illegal character in path at index 45:
http://subversion-server/repos/app/${SUBVERSION_PATH}/ProjectA

On the flip side, I can't replace the ${SUBVERSION_PATH} with
${env['SUBVERSION_PATH']} as the SVN checkout facility doesn't recognize groovy
syntax.
