Local report unit using scriptlet throws java.lang.NoClassDefFoundError when language = groovy, not with language = java

[mlopez_1]

Hi, I have a local report unit using scriptlet that throws java.lang.NoClassDefFoundError when language = groovy, not with language = java

My environment is: JSS 6.3.1, Windows 10 x64, java.version=1.8.0_92 (Java HotSpot 64-Bit Server VM)

I know there is a similar bug at: http://community.jaspersoft.com/jaspersoft-studio/issues/8446, but nothing solved until now.

The stacktrace is:

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during class generation: java.lang.NoClassDefFoundError: Unable to load class org.sescam.ati.explotacion.mxxireport.MxxiJrUtil due to missing dependency net/sf/jasperreports/engine/JRScriptletException
