Prerequisites 前提条件
To run the play framework, you need Java 5 or later. If you wish to build play from source, you will need the Bazaar source control client to fetch the source code and Ant to build it.
要运行Play框架，你需要Java 5以后的的JDK。如果你想从源码构建play框架，你需要用Bazaar源码控制的客户端去获取源代码并用Ant创建它。
If you are using MacOS, java is just built-in. If you are using linux, make sure to use either the Sun-JDK or OpenJDK (and not gcj which is the default java command on many linux distro). If you are using Windows, just download and install the latest JDK package.
如果你用MacOS系统，java是内建的。如果你用Linux系统，确定你使用的是Sun-JDK或者OpenJDK（不要是gcj，很多linux发行版默认都用gcj作为默认的java环境）。如果你用Windows系统，只要下载并安装最新发行的JDK包。
