Maven 및 Intellij IDEA를 사용하여 JPA 실행 12

Intellij IDEA로 전환 했으므로 RESOURCE_LOCAL 지속성 단위를 사용하여 JPA 엔티티를 테스트하려고합니다. 내 환경은 현재 EclipseLink, MySQL 및 Maven을 사용하고 있습니다. Maven 및 Intellij IDEA를 사용하여 JPA 실행 12

이 순간 내 테스트 클래스는 다음 호출 수행 : 나는 persistence.xml 파일의 이름을 변경하는 경우 지속성 단위 (감지되고

EntityManagerFactory factory = Persistence.createEntityManagerFactory("app-test");

을, 나는 장치를 말하는 오류가 없습니다 얻을 찾을 수 있습니다). 내가 테스트를 실행하는 경우 그러나, 나는 콘솔에 다음과 같은 오류가 점점 오전 :

POM의'<저장소>'섹션을 생략했다는 것 외에도, IntelliJ 11과 Eclipse Indigo에서 나에게 맞는 설치가되었습니다. – Perception

포함 된 저장소 섹션을 사용해 보았지만 작동하지 않습니다. Intellij는 어떻게 운영하고 있습니까? – cardori

죄송합니다. 마지막 의견은별로 의미가 없습니다. IntelliJ에서 응용 프로그램을 어떻게 실행합니까? 상단에있는 녹색 화살표를 사용하여 응용 프로그램을 실행하거나 오른쪽에 maven 섹션을 사용하고 있습니까? – cardori

프로젝트를 제거하고 처음부터 다시 만들었으며 현재 작동 중입니다.
