Question

我的环境配置有问题。我正在使用Eclipse neon.1，Tomcat 8.5，Java版本1.8.0_77，我正在尝试使用Struts 2.5.5创建一个简单的Hello World。

如果我手动将Struts 2.5.5 JAR添加到WEB-INF / lib文件夹，一切正常，但如果我通过Maven添加Struts依赖，当我在Server上运行我的项目时，Tomcat会启动Index Out Of Bound异常。

只有最新版本的Struts（2.5.5）才会出现此问题。事实上，如果我将struts2-core 2.3.31添加到pom.xml（而不是2.5.5），一切都运行良好。

我已经尝试过使用Tomcat 7，Tomcat 8和Eclipse Mars。

我创建了一个动态Web项目，然后将其转换为Maven项目; 我还直接创建了一个Maven项目，但问题仍然存在。

有什么想法解决这个问题吗？

编辑：我在.metadata文件夹的.log文件中找到了整个堆栈异常跟踪。

Answer 1

经过多天的研究，我明白了如何解决这个问题，现在我告诉你该怎么做。

关闭Eclipse;
删除C：\ Users [用户名] .m2 \ repository的内容（如果有的话）使用Windows）或〜/ .m2 / repository（如果您使用的是macOS）;
重新打开Eclipse，右键单击该项目，选择＆＃34; Maven＆＃34;，＆＃34;更新项目......＆＃34;，检查＆＃34;强制更新快照/版本＆＃34;然后点击＆＃34;确定＆＃34;。
在Tomcat服务器上运行您的项目：它现在应该可以使用了！
