maven 手动构建项目

在空目录下面：

D:\test>mvn -B archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=com.stono -DartifactId=my-app

第一次会下载一些jar包，第二次输出：

[INFO] Scanning for projects...[INFO][INFO] ------------------------------------------------------------------------[INFO] Building Maven Stub Project (No POM) 1[INFO] ------------------------------------------------------------------------[INFO][INFO] >>> maven-archetype-plugin:3.0.1:generate (default-cli) > generate-sources @ standalone-pom >>>[INFO][INFO] <<< maven-archetype-plugin:3.0.1:generate (default-cli) < generate-sources @ standalone-pom <<<[INFO][INFO] --- maven-archetype-plugin:3.0.1:generate (default-cli) @ standalone-pom ---[INFO] Generating project in Batch mode[INFO] No archetype defined.

会创建my-app，文件：

D:.|   pom.xml|\---src    +---main    |   \---java    |       \---com    |           \---stono    |                   App.java    |    \---test        \---java            \---com                \---stono                        AppTest.java

pom.xml和App.java文件都中规中矩；

但是pom.xml必须手动修改一下：

       
      
       4.0.0
        
      
       com.stono
        
      
       my-app
        
      
       jar
        
      
       1.0-SNAPSHOT
        
      
       my-app
        
      
       http://maven.apache.org
        
          
       
        1.8
           
       
        1.8
         
        
          
             
        
         junit
              
        
         junit
              
        
         3.8.1
              
        
         test
            
         
      
     

mvn compile 编译

mvn package 打包

mvn install 安装

mvn clean 删除

mvn clean package -U  强制更新依赖，删除那些updated文件 

mvn clean package -o offline编译模式，只使用本地仓库
