使用nutch-default中的默认值尝试了nutch-site.xml的不同配置，我在Windows 10中使用cygwin。尝试了环境变量故障排除等，但没有任何效果。关于如何解决此错误有什么想法吗？
文件 nutch-site.xml 必须是有效的 XML 文档。错误消息表明存在多个根元素。例如，可以使用以下 nutch-site.xml 重现该错误：
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>http.agent.name</name>
<value>my-first-web-crawler</value>
</property>
</configuration>
<configuration>
</configuration>
一旦 XML 语法固定，Nutch 应该能够读取配置文件。
