(二)maven構建第一個項目!

使用命令根據模板構建第一項目

1、進入命令提示符，在D盤創建工作目錄：（eg:mavenProject）,並進入mavenProject目錄：

2、在命令行輸入如下命令

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false

3、輸入以上命令後回車，如有如下信息則表示項目創建成功。

D:\mavenProject>mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4 -DinteractiveMode=false

4、查看創建的項目目錄結構：

D:\mavenProject\my-app>tree
卷 軟件 的文件夾 PATH 列表
卷序列號爲 000000E1 5078:7E69
D:.
└─src
    ├─main
    │  └─java
    │      └─com
    │          └─mycompany
    │              └─app
    └─test
        └─java
            └─com
                └─mycompany
                    └─app

D:\mavenProject\my-app>

5、進入項目根目錄，使用maven進行項目編譯

D:\mavenProject\my-app>mvn compile

出現以下信息則表示編譯成功

[INFO] Changes detected - recompiling the module!
[INFO] Compiling 1 source file to D:\mavenProject\my-app\target\classes
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time:  23.813 s
[INFO] Finished at: 2019-02-15T21:40:40+08:00
[INFO] ------------------------------------------------------------------------

D:\mavenProject\my-app>

編譯後文件在target目錄下的classes文件夾下找到。

6、執行以下命令打包編譯文件

D:\mavenProject\my-app>mvn package

執行後提示如下信息則表示打包成功

[INFO] Building jar: D:\mavenProject\my-app\target\my-app-1.0-SNAPSHOT.jar
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
