[RobinCai1993]

I'm installing oqa for a project experiment and finally get to the last step... But when run the command: sbt 'run-main edu.knowitall.eval.qa.QASystemRunner questions.txt output'

An error occurs: [info] Loading project definition from /Volumes/robin_mobile/oqa-master/oqa-core/project [info] Set current project to oqa (in build file:/Volumes/robin_mobile/oqa-master/oqa-core/) [info] Updating {file:/Volumes/robin_mobile/oqa-master/oqa-core/}oqa-core...
