Hibernate groovy+；jpa&x2B；maven=javax/xml/transform/Source的加载程序约束冲突

如果从groovy脚本创建JPA EntityManager，则会出现以下错误：

java.lang.LinkageError: loader constraint violation: loader (instance of <bootloader>) previously initiated loading for a different type with name "javax/xml/transform/Source"
at javax.xml.validation.SchemaFactory.newSchema(SchemaFactory.java:594)
at org.hibernate.ejb.packaging.PersistenceXmlLoader.loadURL(PersistenceXmlLoader.java:89)
at org.hibernate.ejb.packaging.PersistenceXmlLoader.deploy(PersistenceXmlLoader.java:168)
at org.hibernate.ejb.Ejb3Configuration.configure(Ejb3Configuration.java:310)
at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:55)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:48)
...

java.lang.LinkageError:加载程序约束冲突：加载程序（的实例）以前为名为“javax/xml/transform/Source”的不同类型启动加载
位于javax.xml.validation.SchemaFactory.newSchema（SchemaFactory.java:594）
位于org.hibernate.ejb.packaging.persistencexmloader.loadURL（persistencexmloader.java:89）
位于org.hibernate.ejb.packaging.persistencexmloader.deploy（persistencexmloader.java:168）
位于org.hibernate.ejb.Ejb3Configuration.configure（Ejb3Configuration.java:310）
位于org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory（HibernatePersistence.java:55）
位于javax.persistence.persistence.createEntityManagerFactory（persistence.java:48）
...

如果我从java类中的主方法创建EntityManager，它将正常工作

我使用mave，pom中的依赖项如下所示：

有人能告诉我我做错了什么，我该如何解决

javax.xml.transform.Source现在是JDK 6的一部分。似乎某些依赖项（可能是Hibernate）间接依赖于XMLAPIsJAR文件（实际上还包含java.xml.*类）。您必须找到该依赖项并排除XMLAPI
