将 Maven 依赖项添加回 GraphHopper 的类路径会导致工作 Tomcat 服务器失败
Adding Maven dependencies back into GraphHopper's Classpath causes a working Tomcat server to fail
我必须以我在 Java 方面完全是新手这一事实作为我的问题的开头。我一直在尝试在本地 tomcat 服务器上托管 graphhopper，在我的进度崩溃之前，我直接读到了在线指南的末尾 here。
在执行本指南的最后一步之前，我可以让 Eclipse 启动 tomcat 服务器，但我得到 NoClassDefFoundError 并且 localhost 为空。因此，我按照指南中的说明使用 Jar 文件并将所有 Maven 依赖项加载回类路径中。尝试 运行 此服务器现在会导致关于 catalina.LifecycleException （以及其他）的几个 "severe" 错误，并且服务器将无法加载。我在最后包含了错误日志。
我在网上搜索了有关 catalina 的错误，对所有问题的唯一回答是 Tomcat 使用的 JDK/JRE 版本与 Eclipse 使用的版本之间存在冲突。我花了很长时间研究这个，我已经确认 JAVA_HOME 和 Eclipse 中选定的 JRE 指向完全相同的文件夹。我已经尝试使用 JRE 和 JDK 来获得相同的响应，两次都是从头开始。我还将 CATALINA_HOME 设置为正确的 Tomcat 文件夹。我能够从 startup.bat 中单独加载 Tomcat 以查看成功启动画面。
这是我正在使用的：
JDK 8u45 或 JRE 8u45
Eclipse（火星版 4.5.0）
Tomcat8.0.23
我缺少一些基本的理解，为什么 Tomcat 在我加载这些依赖项（最后的屏幕截图）之前可以很好地与 Eclipse 一起工作，所以我似乎无法取得任何进展。任何帮助或指导我前进的人都将不胜感激；先感谢您。
