POM failure application resources

Even with an src/main/resources and the requisite ApplicationResource.properties, ApplicationResource_default.properties and the "en_US" designation, the pom second below is unable to find the first used message key. The error is below. Can someone clarify?

javax.servlet.jsp.JspException: Missing message for key "label.common.title" in bundle "(default bundle)" for locale en_US
