bamboo + perforce: no output for {p4 command}

[mdurant32]

I've been using Bamboo successfully with SVN for a while now, but have recently been compelled to switch to Perforce; so I've been updating my build to accommodate it. I've hit a problem that I can't seem to resolve, though, where I can't get the build to pull the source code down from Perforce. Here's the error message I'm getting when I run the build plan:

java.lang.RuntimeException: com.atlassian.bamboo.repository.RepositoryException: Could not retrieve latest change number for //depot2/def/... //def/...

Part of what's confounding is that I can execute that same command (/home/developer/Perforce/p4 changes -m 1 -s submitted //depot2/def/... //def/...) as the system's "bamboo" user without a problem, and I get one line with the change number and the message of the last submit, and another line about the command assuming that that "//def/..." view is at localhost (which is true).

I'm not sure where to take this from here, so any suggestions are appreciated!

Turns out it was a permissions problem that was corrected by changing my workspace mapping from "//depot2/def/... //def/..." to just "//depot2/def/..." and checking off the box to let Bamboo manage my workspace. All set now!
