我有兩個Visual Studio數據庫項目。在我的本地開發環境中都能很好地開發。 在TFS構建服務器，具有TFS構建包含兩個projcets解決方案，建立一個精細和其他失敗，此錯誤：在TFS構建服務器上構建VS數據庫項目的問題
Task "SqlBuildTask"
Creating a model to represent the project...

我注意到在構建日誌下面的差異，我認爲這是有關，但我不知道是什麼原因造成的。
良好的項目：
Overriding target "Build" in project "C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets" with target "Build" from project "C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\TeamData\Microsoft.VisualStudio.TeamSystem.Data.Tasks.targets".
失敗項目：
Overriding target "Build" in project "C:\Windows\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets" with target "Build" from project "C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\TeamData\Microsoft.Data.Schema.Common.targets".
兩個數據庫項目包括下面的導入（只）：
<Import Project="$(MSBuildExtensionsPath)\Microsoft\VisualStudio\v9.0\TeamData\Microsoft.Data.Schema.SqlTasks.targets" />
線索的歡迎！
