Greetings!

New user here, looked around on the forums before making this forum/chat to ask, even used GPT.

I seem to have encountered an error while trying to boot up the "sexscripts.jar" through the Java application, says

"Groovy error!
java.lang.NoClassDefFoundError: groovy/lang/GroovyShell
Caused by: java.lang.ClassNotFoundException: groovy.lang.GroovyShell
Helpful system informations to resolve it on the forum:
os.name: Mac OS X
os.arch: x86_64
java.version: 1.8.0_441
file.encoding: UTF-8
language: en_US" (Figured I'd share this...)

Any chance anybody knows what's happening?

Perhaps this Java version (java.version: 1.8.0_441), but it should be supported.
Most probably : the erros says it couldn't find the file "lib/groovy-2.5.21.jar". Maybe missing, badly downloaded, or not unzipped, or moved.
