创建一个新项目：
mvn archetype:generate -DgroupId=cn.net.comsys.ut4.simpleweather -DartifactId=simple-weather -DpackageName=cn.net.comsys.ut4.simpleweather -Dversion=1.0
generate目标文档：Generate project in batch mode
为pom.xml添加一些项目信息如下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

Maven Exec 插件
install成jar后可以通过exec执行main方法
mvn exec:java -Dexec.mainClass=org.sonatype.mavenbook.weather.Main
Exec 插件让我们能够在不往 classpath 载入适当的依赖的情况下，运行这个程序
查看exec插件目标以及参数帮助：
mvn help:describe -Dplugin=exec -Dfull
查看项目依赖：
mvn dependency:resolve
mvn dependency:tree
执行单元测试：
mvn test
忽略测试失败：<testFailureIgnore>true</testFailureIgnore>
<project>
[...]
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
</plugins>
</build>
[...]
</project>
也可以通过命令行参数设置
mvn test -Dmaven.test.failure.ignore=true
跳过单元测试：
mvn install -Dmaven.test.skip=true
构建一个打包好的命令行应用程序
想pom.xml增加一下内容
<project>
[...]
<build>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
</plugins>
</build>
[...]
</project>
运行以下命令进行装配：
mvn install assembly:assembly
