Is this an old company project? As maven-compiler-plugin is showing as v3.5.1 and that was released in Feb 2016. Also the group id com.mypack is not in maven central so probably in an internal company nexus or artifactory. So you might need to search for someone who previous built it.
If you search for EJBClientResult.java within your structure do you find it? Does `mvn clean verify -DskipTests` work? as it might be it's within a module of your parent project.
