I install archetype conf 2; pom and web app then I added core module to the project. As I add all the modules on the list of modules for Community edition the error occurs upon launching the magnolia web app.

Servlet.service() for servlet [default] in context with path [/app-webapp] threw exception [Filter execution threw an exception] with root cause
java.lang.ClassNotFoundException: org.springframework.core.NestedIOException

Can anyone help me with this?

I'm a newbie in Magnolia CMS 

Thanks
