我的Maven依赖项是ClassNotFound Exception或NoClassDefFoundError

Question

这里再次（我不得不重写它以使其更全面我猜）：

我得到了项目X和项目Y.他们彼此独立。当项目X使用所有hibernate依赖项时，我在项目Y上获得具有相同依赖项的ClassNotFound Exceptions和NoClassDefFoundErrors。这些错误发生了，因为hibernate jar似乎没有部署在项目Y上。我必须将它们jar放在WEB-INF / lib文件夹中，它们是为运行时部署的，而在项目X中它们已经通过依赖项部署了。区别：项目Y有一个父项目。

这里是pom.xml：

我已经尝试this尝试，但一切都已设定。
