Rythm设置 home.template 配置项后运行报错 403.10 禁止访问：配置无效 

小白请教~~最近学习Rythm，跟着教程在做例子时报错。教程地址：http://rythmengine.org/doc/tutorial.md#env
代码如下：

import org.rythmengine.Rythm;
import java.util.*;

public class HelloWorld {
    public static void main(String[] args) {
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("home.template", "resources");
        Rythm.init(map);
        System.out.println(Rythm.render("helloworld.html", "World"));
    }
}

请问home.template是在配置文件中存在么，教程中没有提到这个配置在哪里。
报错信息空指针异常，具体如下：
