groupId是指com.xx 组织标识

artifactId才是项目名称

2)编译源代码

mvn compile

    3)编译测试代码

mvn test-compile

    4)清空

mvn clean

    5)运行测试

mvn test

    6)生产站点目录并打包

mvn site-deploy

    7)安装当前工程的输出文件到本地仓库

mvn install

    8)打包

mvn package

    9)先清除再打包

mvn clean package

    10)打成jar包

mvn jar:jar

    11)生成eclipse项目  

mvn eclipse:eclipse

    12)查看帮助信息

mvn help:help

   13)查看maven有哪些项目类型分类

mvn archetype:generate -DarchetypeCatalog=intrenal

 

创建一个maven archetype webapp项目

配置如下:

<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/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.saw</groupId>
  <artifactId>test1</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>test1 Maven Webapp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <build>
		<finalName>test1</finalName>
		<plugins>
			<plugin>
				<groupId>org.apache.tomcat.maven</groupId>
				<artifactId>tomcat7-maven-plugin</artifactId>
				<version>2.2</version>
				<configuration>
					<url>http://localhost:8080/manager/html</url>
					<server>tomcat</server>
				</configuration>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-war-plugin</artifactId>
				<configuration>
					<archive>
						<addMavenDescriptor>false</addMavenDescriptor>
					</archive>
					<webResources>
						<resource>
							<directory>src/main/resources/</directory>
							<targetPath>WEB-INF/classes</targetPath>
							<filtering>true</filtering>
						</resource>
					</webResources>
				</configuration>
			</plugin>
		</plugins>
		<defaultGoal>compile</defaultGoal>
	</build>
</project>

直接build就可以打成war包 debugConfiguration tomcat:run
