Custom package exception- com/automationanywhere/commandsdk/i18n/MessagesFactory

I created one custom package and it is working fine by testing the code using test class in IntellJ. When i am using the .jar file in AutomationAnywhere, it is throwing com/automationanywhere/commandsdk/i18n/MessagesFactory exception.

I am using gradle build shadowjar command to generate the jar file. Please help
