Building Docs Don't Mention tools.jar Dependency #19

Closed MusikPolice closed 10 years ago

MusikPolice commented 10 years ago

When building the project for the first time, I got the following exception while running mvn install:

It looks like the JMockIt dependency requires Java's Attach API to function. As far as I can tell, it's necessary to add tools.jar to the classpath on Unix/Mac OSX systems. See this StackOverflow answer for details.

jmockit is not actually used, so I'm removing it
