我正在使用 liferay 6.1.1 ce ga2，当我下载基于 liferay 6.1.x 创建的知识库 portlet 并运行 ant build-service 时，会出现一些“无法解析为类型”的错误。您可以从附件中找到完整的错误信息。即使我使用通过liferay门户在线安装并运行良好的portlet，然后我将安装的文件从捆绑的tomcat目录复制到驻留在plugins sdk的portlet中的portlet目录并再次运行ant build-service，仍然出现错误。
有趣的是，它昨天一次又一次地成功，但今天却失败了。我今天做的唯一一件事就是基于 maven 设置 portlet 开发环境，但我认为这与错误无关，maven 不会更改插件 sdk 的任何内容。错误信息如下：
