创建maven环境的时候出现的一些问题

Today , I have met two problem in process of buling eclipse+maven development environment.
• Eclipse is running in a JRE, but a JDK is required

Solve: 
1. configure the Window/Preference/java/=>intall/jre, we can add a standard vm in the windows.
2. Open the eclipse.ini, and add “-vm  C:\Program Files\Java\jdk1.6.0_20\jre\bin\javaw” at the top of the document.

• M2eclipse,can not use add-dependency in the pom.xml, the result is zero

Solve:
1. We must rebuild the index of repository. Window/show view/other/maven
2. In the opened window, left bitting local repositories -> local repository, select the rebuild index .
