我刚刚在 Eclipse 上安装了 Maven。如果我运行 pom.xml，我会收到以下错误。
使用 Windows 的人不会收到此错误。我有 Mac OS X。

当我将 slf4j-simple-1.7.5.jr 和 slf4j-api-1.7.5.jar 添加到构建路径时，它可以工作。有没有办法不添加外部罐子？

编辑 2：我通过终端使用 Maven clean 并且有效。我认为问题是 Eclipse 内部的 Maven。

编辑 3：我删除了项目并从 SVN 中检查了它，它以某种方式工作。

如果您的代码使用 slf4j，您还必须将 API 和其中一个实现 jar 添加到您的项目中。所以答案是：不。
