Modify settings.xml and default repository save addresses in eclipse

1. Open Eclipse

2.window-->references-->maven0-->user Settings: Modify User settings,browse to re-select new Location D:\gongsi\ Apache-maven-3.1.0\conf\settings.xml.

When you integrate Maven2 in Eclipse, by default, Eclipse creates a directory under your system disk (c:/),
C:/Documents and settings/danlley/.m2/ Repository
and use it as the Data Warehouse directory. If one day when you are unfortunate need to redo the system, and can not be maven2 warehouse directory in time to transfer the data, you have done to maven2 warehouse all maintenance will mean naught. In order to minimize your loss in maven2, improve the safety factor of your so-called labor outcomes, it is recommended that you migrate your data warehouse as follows:
1. Open Eclipse
2.window-->references--> Java-->build Path-->classpath Variables
3. With the above two actions you will see a variables property named M2_repo
4. Double-click the property or click the Edit button
5. Modify the properties C:/Documents and Settings/danlley/.m2/repository to E:/maven-2.0.4/.m2/repository

OK, and you'll have peace of mind.

Also, if you want to point the post-installation MAVEN2 Data Warehouse to a backup folder simply, you can do so in
e:/maven2/maven2/conf
Below, locate a settings.xml file, open the file, and locate the following node to modify the
<localrepository>e:/maven-2.0.4/.m2/repository</ Localrepository>
Description: The settings here are best as you would in eclipse, in order to consume unnecessary disk space and repeatedly download resources.
But I found that if you download update maven
http://m2eclipse.codehaus.org/update-dev/
You can set my local repo
