2. Automatically compile : can we automate compilation ( similar to executing javac generated class file )
3. Complete the test : to achieve test function, help complete
4. Generate reports : can more easily achieve the management of the project
5. Packaging : Ordinary project to fight jar package, Web projects labeled as war package
6. Project deployment : only one command mvn jetty: run to achieve the project's deployment 

b) jar package dependency management

 

Automatically introducing a corresponding dependencies

(3) Installation

a) Download JDK Download : http://www.oracle.com/technetwork/java/javase/downloads/index.html    

 　　　　Maven：http://maven.apache.org/download.html

d) an access path configuration repository

 

MAVEN_HOME / conf / settings.xml global

Xml copy it over path

 

~ User root path C: \ the Users \ Leven / .m2 / the settings.xml single user , modify user profile

 

Increase <localRepository> F: \ OpenSource \ maven \ repository-teacher \ repository-teacher ( warehouse pack Road King) </ localRepository>

(2) bin / application under setup64

(3) into the hosts file: C: \ Windows \ System32 \ drivers \ etc \ hosts

the "0.0.0.0 account.jetbrains.com" added to the hosts file

Remember permission to modify the hosts

(4) .http: //idea.lanyus.com/ registration code to paste

(5) establish a test project proves successful
