我們之前使用Maven都是直接在Eclipse中創建的，有的時候步驟稍微冒犯些
這裏我們學習下怎樣用命令創建項目

感謝分享。
1. 創建Java項目
-
yuguiyang@onepiece:~/Documents/maven_demo$ mvn archetype:create \
-
> -DgroupId=org.ygy \
-
> -DartifactId=hello_maven
![]()
首次運行命令時，maven會下載一些依賴的jar包
我們等待她運行完就可以了
-
yuguiyang@onepiece:~/Documents/maven_demo$ mvn archetype:create \
-
> -DgroupId=org.ygy \
-
> -DartifactId=hello_maven
-

-
yuguiyang@onepiece:~/Documents/maven_demo$
等看到BUILD SUCCESS就可以了
![]()
（PS
在上面的日誌中，我們看到一條警告
[WARNING] This goal is deprecated. Please use mvn archetype:generate instead
目測是說我們的命令中 mvn archetype:create \ 已經不推薦使用了，廢棄掉了，使用 mvn archetype:generate 代替
我們試下
-
yuguiyang@onepiece:~/Documents/maven_demo$ mvn archetype:generate \
-
> -DgroupId=org.ygy \
-
> -DartifactId=new_code
這次執行時，又下載了一大堆jar包，中間還提示說要選擇版本，直接Enter選擇默認了
最後也是執行成功了的
以後我們還是使用官方推薦的命令吧
