我正在使用IntelliJ Idea x64、Java 1.8、Windows 7。经过多次尝试，我发现问题出在我们公司的代理上 在将我的笔记本电脑与公司网络断开连接，并将其直接连接到互联网之外之后，我可以毫无问题地进行编译 我与Vaadin支持人员进行了交谈，他们猜测许可证试图联系Vaadin服务器以验证其有效性，但最终出现了此错误，该错误与此失败的连接无关
事实上，在成功编译之后，我能够再次编译，甚至在代理之后。看起来小部件编译失败，真正的错误不在代码段中。如果对您隐藏了真正的错误，您可能必须查看您的目标（我不是maven用户，但例如gradle插件为widgetset编译生成了一个日志文件）我使用的参数
