It looks like you have appfuse multi-module web project and you are building the web module without having built/installed the core module.

Quoting the instruction from appfuse quickstart, highlighting relevant portion in bold.

To view your application run mvn jetty:run from your project's directory (for a modular project, you'll need to run mvn jetty:run from your project's web directory (after installing the core module)).

You need to run mvn install from the project's root directory also!

In your situation, you definitely need to mvn install from your core directory. If this does not help, then run the same command from root directory. The problem is that one of Your modules needs to be installed and only after that the error you are encountering will be removed.
