java.lang.NoClassDefFoundError: Could not initialize class com.xxx.xxx.Email, while initializing kotlin class from java class

I need to use an existing Kotlin encryption file in a java class. While trying to do that getting NoClassDefFoundError Exception. The import statements are proper no issues with that. If I run this application from intellij its working, but when I run via terminal with ./gradlew clean build its throwing the error.
