【问题描述】：

我正在尝试编译新创建的 Play Framework 应用程序。我按照说明使用 play-java 模板生成了应用程序并将其命名为 test。我导航到“测试”目录，再次运行 activator.bat 并输入“编译”。这显示了：

我使用的是 Windows 8。提前致谢。

编辑：我设法运行 2.2 没有任何问题，只有 2.3 看不到播放。*

【解决方案1】：

您不必转到子目录。

Activator 或 SBT 应从 build.sbt 文件所在的目录运行（即包含 app 和 test 子目录的父目录）。

一旦 Activator/SBT 像这样启动，就可以使用任务 test 编译和执行测试。
