tomcat找不到maven依赖

Question

几个小时前，我正在开发我的网络应用程序，它运行良好。但不知怎的，一个相当奇怪的问题开始发生，我收到以下错误：

我正在使用 Eclipse 的 m2 maven 插件，项目是 maven webapp。当我使用 tomcat-maven-plugin 时，该项目工作正常，但如果我尝试将其部署到 Eclipse 3.5 IDE 中配置的 tomcat 服务器，则会收到上述错误。

编辑：另外，当我停止 tomcat 时，我最后得到以下信息：

ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2
JDWP exit error AGENT_ERROR_NO_JNI_ENV(183):  [../../../src/share/back/util.c:820]

我记得做的唯一一件事是尝试使用调试模式进行一些调试。

有人可以帮助我理解为什么会发生以及如何解决这个问题吗？

谢谢。

Answer 1

确保您的项目属性中有类似的内容 ->部署组件：
[ Maven 依赖项:: WEB-INF/lib ]

Answer 2

这可能是一个 m2eclipse-wtp bug，它是 eclipse 插件，应该导入 maven war 配置并从中创建 eclipse 项目，包括哪些库应该编译时以及哪些库应该位于 WEB-INF/lib 中。过去的不同版本给我带来了多年来的问题。我总是必须在 Eclipse 项目设置中手动修复这些问题。不同版本的 eclipse 将其设置在不同的位置，因此这并不会让事情变得更容易。
