iOS Xcode Bamboo plugin fails after upgrading to v2.0 of the plugin

[Patrick Aikens]

I'm running Bamboo 4.4.4 and just upgraded to the new iOS plugin v2.0. I now get the following when I try to run a build - it's complaining about the "unlock keychain" task:

17-May-2013 10:27:58	java.lang.IncompatibleClassChangeError: Found class com.atlassian.utils.process.ExternalProcess, but interface was expected

Anyone out there know what I can do to get past this?

i resolved this on our system by uninstalling, then re-installing the plugin.
