Could not instantiate report compiler : net.sf.jasperreports.compilers.JRGroovyCompiler

[mtn]

Hey,

When compiling a report using Jaspersoft Studio 6.2.0.final I get following error: 

net.sf.jasperreports.engine.JRException: Could not instantiate report compiler : net.sf.jasperreports.compilers.JRGroovyCompiler

The preview works correct, I’m able to compile the report using IReport. Can someone advice me on how to solve this? Changing the java version.. (through the ini file) did not solve the issue.

Thanks!

Issue has been resolved by completely removing and reinstalling jaspersoft.
