I have a maven enabled project imported into Eclipse. From Eclipse, I get an error "No generator named "system-uuid" is defined in the persistence unit" on the system-uuid portion of the following lines:

@Id @GeneratedValue(generator = "system-uuid")
@GenericGenerator(name = "system-uuid", strategy = "uuid")
@Column(length = 36)
public String getId() {
    return id;
}

The project builds correctly from the command line. What is causing Eclipse to generate this error and how do I fix it?

The persistence file looks like this..

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence 
    http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version="1.0">
    <persistence-unit name="xxxx"/>
</persistence>
eclipse hibernate persistence.xml
