org.apache.groovy.dateutil.extensions (groovy-dateutil and groovytime)is part of the jar Archives

The execution without shadowJar is error-free.

For Information: groovy 2.5.6, gradle 4.10.2, com.github.johnrengelman.shadow 4.0.4

It seems to be related to groovy extension feature. No pb with groovy in 2.4.16 using groovy-all. Adding mergeGroovyExtensionModules doesn't help.

[lwolter]

I have added
shadowJar { mergeGroovyExtensionModules() }
to my gradle build. Unfortunately the problem is not solved.

Can you try out the latest versions?
