unable to resolve class net.sf.jasperreports.compilers.GroovyEvaluator ... one more time!

[mauro.rulli_1]

I completed my setup on a new computer.

Jaspersoft Studio 6.14.0

When I open a previeously created groovy report i got the exception below. I found a new version (6.15.0) is release, so uninstall the 6.14, download and fresh install of the last 6.15 release.

Just the same, like in many other release as tracked by Google. I tried to update the groovy-all.xxx.jar but I can't run Jaspersoft Studio anymore. Any help please?
