Maven build fails with error 'java.lang.NoClassDefFoundError: org/drools/core/common/ProjectClassLoader' after upgrading BA bom from 7.2.1 to 7.8.1
Issue
In order to upgrade RHDM version from 7.2.1 to 7.8.1 in my application, BA BOM version was changed from 7.2.1.GA-redhat-00002
to 7.8.1.redhat-00002. But after that, maven build fails with the following error wile running the test code .
java.lang.NoClassDefFoundError: org/drools/core/common/ProjectClassLoader
Caused by: java.lang.ClassNotFoundException: org.drools.core.common.ProjectClassLoader
It works with version 7.2.1.GA-redhat-00002. Why does NoClassDefFoundError happen after upgrading to 7.8.1 and how to solve it?
