Java 构建GCM演示服务器应用程序时遇到问题

每当我尝试使用

ant

构建GCM演示服务器时，我都会遇到17个编译错误。似乎缺少一些GCM库。如何解决这些问题

我自己从未运行过此项目，但它似乎缺少extras\google\gcm\gcm server\dist\gcm-server.jar中的库及其依赖项。请将这些库添加到此项目下的libs文件夹中，然后重试。

哦，我想我已经解决了。感谢您提供的信息。我所做的是从gcm服务器复制了build文件夹到gcm演示服务器并覆盖现有的。然后运行ant并编译它，没有错误。这在自述文件“ant-f../。/gcm server/build.xml update demo”中进行了解释。不过，谷歌文档应该更新。按照他们的说明进行操作的每个人都将获得这些compi
