Multiple "Groovy: unable to resolve class..." errors Bonita 6.5.2

Q&A
1

Today I opened my project and am getting multiple Groovy errors.
The errors show up during Validation.
Examples are:

  Groovy script Empty List is not compiling with error: Groovy: unable to resolve class org.bonitasoft.engine.identity.User, Groovy: unable to resolve class org.bonitasoft.engine.bpm.flownode.HumanTaskInstance, Groovy: unable to resolve class org.bonitasoft.bpm.flownode.HumanTaskInstanceSearchDescriptor

I have not made any changes that I know of.

Any help will be greatly appreciated.

Any solution about this? I’m having kind of the same problem.
