For my thesis about composable combinators/search heuristics for constraint programming, I'd like to use ScalaCheck to check properties of the combinators.\r\n\r\nRecently I've written the generators and some basic properties.\r\nI managed to compile them, but when I try to run them, Scala cannot figure out how to run the target.\r\n\r\nTherefore I've tried to run an example from the ScalaCheck user manual (http://code.google.com/p/scalacheck/wiki/UserGuide) from the \"Grouping Properties\" section. Same error arised, also when a friend of mine tried on his computer. My terminal output is below. I use Windows 7, 32 bit, ScalaCheck version is 2.9.0-1.9 and my Scala version is 2.9.0.1\r\nCould you provide me with an idea of what's going wrong?\r\nThanks in advance!\r\n\r\nBest regards,\r\nBenoit Desouter\r\nStudent second master Software Engineering - Ghent University, Belgium\r\nBenoit<DOT>Desouter<AT>UGent<DOT>be\r\n\r\n== Terminal output ==\r\nMicrosoft Windows [Version 6.1.7600]\r\nCopyright (c) 2009 Microsoft Corporation.
