在工作中，需要用到maven。在安装好maven后，在eclipse中安装maven插件时，却遇到了问题，总是提示安装失败。提示信息如下：
Cannot complete the install because one ormore required items could not be found.
Software being installed: m2e - MavenIntegration for Eclipse (includes Incubating components) 1.6.2.20150902-0002(org.eclipse.m2e.feature.feature.group 1.6.2.20150902-0002)
Missing requirement: Maven Integration forEclipse Launching 1.6.2.20150902-0002 (org.eclipse.m2e.launching1.6.2.20150902-0002) requires 'bundle com.google.guava [14.0.1,16.0.0)' but it could not befound
Cannot satisfy dependency:
From: m2e - Maven Integration for Eclipse (includes Incubatingcomponents) 1.6.2.20150902-0002 (org.eclipse.m2e.feature.feature.group1.6.2.20150902-0002)
To:org.eclipse.m2e.launching [1.6.2.20150902-0002]
如上所示，提示缺少依赖的文件。导致这个问题的原因是，我们安装的插件的版本太高了，换成低版本的插件就好了。我安装的版本如下：JDK：1.6，Eclipse：4.2，maven：7。
解决办法：在Eclipse中点击Help->Install New Software，在work with中点击Add，Name输入m2e_new，Location输入http://download.eclipse.org/technology/m2e/milestones/1.4，然后就可以看到m2e插件了。全部选中，安装后重启Eclipse即可。截图如下：
