RavenDB Java客户端缺少StringUtils的

Question

我下载了RavenDB Java客户端3.2.1罐子从here，在Ecplise创建了一个新的Java项目，增加了罐子引用列表，然后带着这三条线

IDocumentStore store = new DocumentStore(ravenDbUrl, "todo-db"); 
store.initialize(); 
store.executeIndex(new TodoByTitleIndex()); 

从here，用我的特定于db的名称替换了这些值，并期望从db获得一些生命迹象。相反，我得到“Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/StringUtils”。 我必须承认，自从我完成Java之后已经有一段时间了，但是这肯定不会错过显而易见的东西，是吗？！ 我也包含了commons-lang3-3.5.jar文件，但它没有考虑到这一点。你能否指点我正确的方向？

谢谢！

将“官方”pom添加到我的Eclipse项目中，使其编译并运行。 为了记录在案，这里的POM，万一有人需要从基础研究：
