Answer 1

Eclipse Juno和Indigo在使用捆绑的maven版本(m2e)时，不会取消消息slf4j:Failed to load class“org.slf4j.impl.StaticloggerBinder”。从m2e版本1.1.0.20120530-0009及以后的版本中就会出现这种情况。

尽管这被指示为错误，您的日志将正常保存。突出显示的错误将仍然存在，直到该错误得到修复。有关此方面的更多信息，请参阅m2e支持站点。

当前可用的解决方案是使用外部maven版本，而不是Eclipse的捆绑版本。您可以在下面的问题中找到关于这个解决方案和关于这个错误的更多细节，这个问题与您面临的问题完全相同。
