I am learning to work with Jacoco to optimize code coverage but I am having
trouble building the build file with Jacoco. I have read the tutorial at
http://www.eclemma.org/jacoco/trunk/doc/ant.html#coverage and have used
much of their sample build.xml to work on my own. Now I am getting this
error: Error while creating report. It seems fairly vague so could someone
help me figure out why this isn't working? Also the documention spoke about
the necessity to include fork="true" within the coverage section but testng
doesn't accept fork as an attribute.
