I'm trying to use the Compatibility features in Jaspersoft Studio 6.5.1(latest), but I get the following error when compiling reports:
"package net.sf.jasperreports.engine does not exist".
I use properties > Jaspersoft Studio > Compatibility to load previous versions of jasper reports.
I then select a previous version for the compiler
I also tried adding the legacy versions directly to the build path...
..But that didn't resolve the error. I'm running it on Ubuntu.
If you download the jasperreports-x.x.x-project.zip from sourceforge and unzip each one, then set the JasperStudio managed version location at each folder you unzipped to you should hopefully find that solves your problem
