playframework - Play Framework 2.3 - 不检测变化

Question

每当我对我的 Play 应用程序进行更改时，它不会重新编译(自动重新加载？)更改，并且当我刷新页面时，我会看到该应用程序的旧版本。每次更改源代码时，我都必须 Control + D，这很不方便。

我在旧应用程序上尝试过，创建了新应用程序，activator clean，activator ~ run ... 没有帮助

...有什么想法吗？

使用 this 让它工作对 Github 上提交的问题的回答

The simplest workaround is to use polling instead, by adding the following to your build:

PlayKeys.playWatchService := play.sbtplugin.run.PlayWatchService.sbt(pollInterval.value)

Note that I would not use this in combination with ~run, because it will mean that Play and sbt will both be polling for changes in 2 separate threads, which is going to chew up a lot of cpu. Rather, just use it with run.
