IDEA 下，如何解决 Failed to read schema document '...dubbo.xsd' 无法读取文档

阿里的域名关闭了，只能引用本地的 dubbo.xsd ，这在 Eclipse 中就是添加一条记录就好了 最近转到 IDEA 下，搜索了一圈没找到解决方法，诸位有遇到这种问题么

org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 77; schema_reference.4: Failed to read schema document 'http://code.alibabatech.com/schema/dubbo/dubbo.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not xsd:schema.
