I am trying to create a headless build of a project using Rational Build Utility (RBU) using  a batch script and Ant.
I generated my password.txt file using  the build engine. We are using RTC 4.05.

Does anyone have any idea on how to fix this error/get around it/whats causes it?

Thank you,

Example Values being passed to <teamFetch> Ant task:
repositoryAddress=https://ourrationalbuild:9445/ccm/
userId=_someid
passwordFile=C:\Workspaces\Test2/build/password.txt
workspaceName=_someids project Workspace
destination=C:\Workspaces\Test2/Workspace-RTC
verbose=true

Ant Task:
<teamFetch repositoryAddress="${repository.address}" userId="${user.id}" passwordFile="${build.project.location}/${password.file}" workspaceName="${repository.workspace}" destination="${workspace.location}" verbose="true" />

Error:
BUILD FAILED
