希望有人能够解决我一直在努力解决的问题。我正在将一个小项目从GWT更改为Vaadin，我的所有库都在工作，除了Oracle JDBC驱动程序（ojdbc6.jar）。阅读后我发现这个库不能通过公共Maven回购获得，所以我开始尝试从我的本地文件系统添加到Ivy。
这是问题所在。我已经能够让Ivy解决依赖关系并将其添加到常春藤缓存中，但它只会将其添加到我的lib / jars文件夹而不是添加到WAR \ WEB-INF \ lib文件夹中。所有其他依赖项似乎都按预期工作并部署到WEB-INF \ lib文件夹，C3P0可以启动数据库池，但在尝试加载JDBC驱动程序时失败。
我的文件系统设置是ivy-settings.xml中列出的第一个解析器 - 希望有人可以提供帮助！

在eclipse中看看你的项目属性。有一个称为“部署程序集”的点，它至少应包含这两个条目：
/src -> WEB-INF/classes
/WebContent -> /
然后你可以添加
/Ivy -> WEB-INF/lib
确保部署程序集中包含所有需要的库。
