在工作中，需要用到maven。在安裝好maven後，在eclipse中安裝maven插件時，卻遇到了問題，總是提示安裝失敗。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，提示缺少依賴的文件。導致這個問題的原因是，我們安裝的插件的版本太高了，換成低版本的插件就好了。我安裝的版本如下：JDK：1.6，Eclipse：4.2，maven：7。
解決辦法：在Eclipse中點擊Help->Install New Software，在work with中點擊Add，Name輸入m2e_new，Location輸入 http://download.eclipse.org/technology/m2e/milestones/1.4，然後就可以看到m2e插件了。全部選中，安裝後重啓Eclipse即可。截圖如下：
