在我们的VStudio 2015解决方案中，我们有一系列SSDT。其中一个返回异常“SqlBuildTask”任务意外失败。Microsoft.Data.Tools.Schema.Sql.Build.BuildFailedException：具有相同密钥的条目已存在。“。我走进Microsoft.Data.Tools.Schema.SqlTasks.targets并采取一看（以下张贴）“”SqlBuildTask“任务意外失败......”SSDT中的异常

</SqlBuildTask>
On our previous sprint, the build and deploy of the project was working fine. When I did a TFS compare with the previous version there are no major differences.
这是我已经做了：
我有升级到SSDT最新版本（没有解决它）
删除Microsoft.Data.Tools.Schema.SqlTasks.targets文件和修复SSDT安装目录（没有任何解决它）
我仍然在寻找目标的任何重复键文件作为例外，指出
任何帮助将不胜感激...
