我正在用我的Java代码构建一个odata服务，当我尝试运行它时，出现以下错误：
java.lang.ClassNotFoundException: org.apache.olingo.commons.api.edm.provider.CsdlEdmProvider
这是我在以下位置运行该应用程序的tomcat的完整日志：

到目前为止，根据我的研究，有关java.lang.NoClassDefFoundError的问题是，在大多数情况下，类加载器在运行时找不到类（在本例中为.jar）。
我现在正在使用Eclipse Photon，但是Eclipse Oxygen也遇到了同样的问题。
还使用了Tomcat 8和9。
这是我正在关注的教程tutorial
我非常感谢有关如何解决此问题的任何提示
