Question

我在新创建的Play 2.1.3应用程序上收到此错误。我正在运行Java 7u25。我创建了新的应用程序，并在应用程序目录中使用“play run”运行它。

Unexpected exception
Compilation failed without reporting any problem!?

有什么理由不能使用JDK 1.8吗？还有哪个版本的SBT，以及你使用的scala版本？我有类似的事情发生并经历了一些失败（尽管通常有某种形式的错误报告）。

我的解决方案是使用SBT版本0.13.15或1.0.3

您可以在/project/build.properties文件中指定SBT构建版本

 if (v > 0)
 {
     //Build the custom Query
     foreach (string s in fields)
     {
         exportQuery += s;
     }
     //tack on the closing semicolon
     exportQuery += ";";
     Program.conn.Open();
     using (MySqlCommand data = new MySqlCommand(exportQuery, Program.conn))
     {
         data.Prepare();
         for (int f = 0; f < v; f++)
         {
             data.Parameters.AddWithValue("\"" + placeholders[f] + "\"", parameters[f]);
         }
         //Datatable prep
         exportTemp = Program.FillTable(data);/*this runs the query through the database*/
      }

也可以尝试使用scala版本2.11.8，我发现它非常稳固！（您可以在build.sbt文件中设置它）

sbt.version=0.13.15
