I am new here and this would be my first question, hope to get some inputs from my seniors here:

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.1.RELEASE:run (default-cli) on project proman-api: An exception occurred while running. null: InvocationTargetException: Cannot load configuration class: apps.proman.api.PromanRestApplication: ExceptionInInitializerError: java.lang.reflect.InaccessibleObjectException-->Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError

This is a huge roadblock as I am unable to open swagger.

Also a little gist: I am learning FSD from upgrad and I have an existing POM file (which we are advised not to edit).

Any help is appreciated.

Thank you in advance
