我运行“activator ui”命令并选择“play-scala-intro”。 Activator克隆新项目，编译并运行它没有任何问题。
然后我再次点击“开始编译”按钮，激活器记录：
Waiting for threads to exit or System.exit to be called. Waiting for thread run-main-0 to terminate. Interrupting thread run-main-0 Interrupted run-main-0 Thread run-main-0 exited. Interrupting remaining threads (should be all daemons). Sandboxed run complete.. Nonzero exit code: -1 (echo:run) Nonzero exit code: -1 Run complete.
Compilaction失败，无法再次运行演示。 即使重新启动激活剂后，我也能获得相同的结果。
我做错了什么？如何解决？
亲切的问候 卡米尔
