Question

我刚在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清洁并且有效。我认为问题是Eclipse中的Maven内部。

编辑3：我删除了这些项目，并从SVN中检查了所有项目，并且它以某种方式工作。

Answer 1

如果您的代码使用了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：没有。

java.lang.ClassNotFoundException：org.slf4j.LoggerFactory Maven
