无法将 Web 应用程序部署到 debian 虚拟服务器上的 tomcat7
Unable to deploy web application to tomcat7 on debian virtual server
我正在使用 jersey 编写简单的 Java 后端，我想将它部署到虚拟服务器 运行 Debian。我想，我已经正确安装了 tomcat7 和 tomcat7-admin，并且还正确设置了用户角色（manager-gui 和 manager-script）。
访问http://my-ip-address:8080时可以看到tomcat运行。我也可以通过 http://my-ip-address:8080/manager/html 访问管理器，所以我认为 tomcat 配置正确。
问题是，当我想部署我的 Web 应用程序（使用 tomcat7-maven-plugin）时，部署本身不起作用。这是来自 Maven 的跟踪：

我不知道上面的错误是什么意思，因为我能够使用 idea（不是 maven-tomcat-plugin）将这个应用程序部署到我的本地 tomcat。我会尽量提供所需的信息，因为我需要尽快解决这个问题。
我读了一些关于类似失败的线程，在那里，解决方案是将 javax.servlet-api 的范围设置为 provided。在我的 pom.xml 中我没有这种依赖性，因为 jersey-servlet 已经提供了它，所以我没有其他关于如何解决这个问题的想法。
