导入dubbo项目到Eclipse，配置文件报了如下异常：
Multiple annotations found at this line: - cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'dubbo:application'. - 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>.
解决方案：
1、下载一个dubbo.xsd文件
2、windows->preferrence->xml->xmlcatalog
add->catalog entry->file system选择刚刚下载的文件路径
key type选择schema locaiton
修改key值和配置文件的http://code.alibabatech.com/schema/dubbo/dubbo.xsd 相同
