I'm passing an argument with a space to a Maven build (-Dsqlcmd.auth="-U sa -P xxxxxxxx"). Bamboo is tokenizing it correctly as a single argument, but Maven sees it as separate arguments and fails:

> [WARNING]
> Profile with id: 'xxxxxxxx' has not been activated.
...
> build 11-Jul-2011 20:37:51 [INFO] ------------------------------------------------------------------------
> build 11-Jul-2011 20:37:51 [ERROR] BUILD FAILURE
> build 11-Jul-2011 20:37:51 [INFO] ------------------------------------------------------------------------
> build 11-Jul-2011 20:37:51 [INFO] Invalid task 'sa': you must specify a valid lifecycle phase, or a goal in the format plugin:goal or pluginGroupId:pluginArtifactId:pluginVersion:goal
> build 11-Jul-2011 20:37:51 [INFO] ------------------------------------------------------------------------
> build 11-Jul-2011 20:37:51 [INFO] For more information, run Maven with the -e switch

Suggesting that Maven's seeing 'sa', '-P' and 'xxxxxxxx' as separate arguments.
