eclipse安装maven插件的问题

1. 安装插件出现No repository found at http://m2eclipse.sonatype.org/sites/m2e错误

        后来用如下地址安装成功：

        http://download.eclipse.org/technology/m2e/releases

   2.  如果 你在安装的时候报如下错误：

         Cannot complete the install because one or more required items could not be found.
  Software being installed: m2e - Maven Integration for Eclipse 1.4.0.20130601-0317 (org.eclipse.m2e.feature.feature.group 1.4.0.20130601-0317)
  Missing requirement: async-http-client 1.6.5.20130531-2315 (com.ning.async-http-client 1.6.5.20130531-2315) requires 'package org.slf4j 1.6.2' but it could not be found
  Cannot satisfy dependency:
    From: Maven Archetype Common Bundle 1.4.0.20130531-2315 (org.eclipse.m2e.archetype.common 1.4.0.20130531-2315)
    To: bundle org.eclipse.m2e.maven.runtime [1.4.0,1.5.0)
  Cannot satisfy dependency:
    From: m2e - Maven Integration for Eclipse 1.4.0.20130601-0317 (org.eclipse.m2e.feature.feature.group 1.4.0.20130601-0317)
    To: org.eclipse.m2e.archetype.common [1.4.0.20130531-2315]
  Cannot satisfy dependency:
    From: Embedded Maven Runtime Bundle 1.4.0.20130531-2315 (org.eclipse.m2e.maven.runtime 1.4.0.20130531-2315)
    To: bundle com.ning.async-http-client [1.6.5,1.6.6)

说明它缺少 slf4j 的依赖

点击installing software 输入 http://www.fuin.org/p2-repository/

点开 "Maven osgi-bundles" 

然后选择 "slf4j-api" 安装

再执行第一步操作

3. 如果你在安装的时候出现如下错误：

   Cannot complete the install because of a conflicting dependency.
  Software being installed: m2e - Maven Integration for Eclipse 1.4.0.20130601-0317 (org.eclipse.m2e.feature.feature.group 1.4.0.20130601-0317)

  Only one of the following can be installed at once:

说明你的插件版本过高，需要依赖的包此eclipse暂时没有，所以你可以下载如下版本，前提是你要卸载之前的版本
