When PUCM creates the read-only branch for the stream and there is no "Hudson" project available the stream is created in the current project instead, and a warning is issued:'

The build project was not found. You can create the project with: "cleartool mkproject -c "Your special build Project" -in rootFolder@\your_pvob yourBuildProject@\your_pvob".
Since there's no build project in ClearCase, pucm have made an extra stream in your integration stream to build in

Problem is that this instruction is not correct:

If you create the UCM project named "Hudson" from the GUI you are OK, but if you created it using the cleartool command above you will get a UCM project without an integration stream, so it's not enough. you have to go something like:

cleartool mkproject -c "Hudson project" -in RootFolder@[YOUR PVOB] hudson@[YOUR PVOB]
cleartool mkstream -int -in project:hudson@[YOUR PVOB] hudson_int@[YOUR PVOB]
