oracle – 无法使用EFPowerTools Beta2 VS2012对代码进行逆向工

我想起首行使PowerTools对代码举办逆向工程.当我从当地MS-SQL数据库举办逆向工程时,它可以事变,但不能从Oracle DB中举办.我在输出节制台中收到以下错误：

System.Data.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. ---> Oracle.DataAccess.Client.OracleException: ORA-1005: null password given; logon denied
   at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode,OracleConnection conn,IntPtr opsErrCtx,OpoSqlValCtx* pOpoSqlValCtx,Object src,String procedure,Boolean bCheck)
   at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode,Object src)
   at Oracle.DataAccess.Client.OracleConnection.Open()
   at Oracle.DataAccess.Client.EFOracleProviderServices.GetDbProviderManifestToken(DbConnection connection)

   at System.Data.Entity.Design.EntityStoreSchemaGenerator..ctor(String providerInvariantName,String namespaceName)
   at Microsoft.DbContextPackage.Handlers.ReverseEngineerCodeFirstHandler.ReverseEngineerCodeFirst(Project project)

我可以通过右键单击项目>来正常天生EF文件.添加> ADO.NET实体数据模子>选择“从现稀有据库”并凭证领导的别的部门.我更喜好powertools,缘故起因有几个(首要是映射为.cs文件).行使Oracle时为什么不能举办逆向工程？ TIA
