我尝试在netbeans 8.0.1上使用hibernate，spring和jpa运行一个Web应用程序，但是现在我在编译应用程序时遇到了这个异常...以下是错误：
Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default- compile) on project SMSXxxxx: Compilation failure: Compilation failure:
error: Problem with Filer: Attempt to recreate a file for type com.equitel.smsmanager.entities.TextMessageContent_
error: Problem with Filer: Attempt to recreate a file for type com.smsmanager.entities.SmsUser_
这是持久性单元，我的项目中只有一个
