Akka - Deprecation编译错误

Question

我决定对付阿克卡..。在编译之前，这是非常棒的:-/运行Ubuntu。

我到目前为止所做的事：

1. 安装了JRE和JDK 7
2. 下载/提取Akka
3. 下载和安装Maven
4. 设置路径变量等

所有遵循本教程的教程

编译时，我得到以下错误

我真的复制了ans，粘贴了他们最后的Pi.java文件，并试图编译，我完全不知道该如何继续下去？

任何想法都会很好。

开始使用Akka的最好方法是使用Typesafe的激活器：其中有几个教程向您展示了如何做不同的事情，从“Hello”到使用高级集群特性，您可以看到完整的列表这里。

尽管如此，您的问题来自于尝试从Akka 2.2.1上的2.0.2文档中运行一个教程，这将无法工作。
