关于sbt：为什么使用激活器测试从Play 2.2.2迁移到2.3后为何不执行测试？

Why are no tests executed after migration from Play 2.2.2 to 2.3 with activator test?

我将我的应用程序从Play 2.2.2升级到了2.3。我的应用程序运行良好。

有时activator test给出以下输出：

[info] Loading project definition from /Users/myapp/project
[info] Set current project to myapp (in build file:/Users/myapp/)
[info] Compiling 23 Scala sources and 180 Java sources to /Users/myapp/target/scala-2.10/classes...
[info] Compiling 55 Java sources to /Users/myapp/target/scala-2.10/test-classes...
[success] Total time: 112 s, completed 24 juin 2014 17:53:06

就是这样...没有运行测试。如果我尝试运行testOnly，则找不到它。

此外，即使我不更改任何文件，每次尝试测试应用程序时，都会重新编译源代码。 Play 2.2并非如此。

我什至没有更多要显示的日志。当我尝试使用activator ui进行测试时，我有更多的日志，但也没有运行任何测试。

如果我手动删除文件夹project/project，project/target和target，并运行命令activator test，则对于每个测试类，都会收到以下错误：
