Question

I am getting this exception java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7 and java.lang.NoClassDefFoundError: Coul

Answer 1

Move to JDK 11, it should work.

Answer 2

In my case the combination was IntelliJ 2020.2, Kotlin 1.3.72, Maven 3.6.1 and SpringBoot 2.2.1 application. No Gradle used at all in the project.

Somehow IntelliJ had switched to use OpenJDK14 - when reverting back to OpenJDK11 everything started to work again.
