Maven 命令操作项目

1.创建一个多模块的Java项目

shift+鼠标右键

创建项目命令：

旧版：

mvn archetype:create -DgroupId=com.qhong -DartifactId=MavenParent -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

新版：

mvn archetype:generate -DgroupId=com.qhong -DartifactId=MavenParent -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

发现就改变一个单词，新版创建的速度真是太慢了

用旧版方式创建报错：

网上进行查找，发现在maven3.0.5以上版本舍弃了create，使用generate生成项目，我的是3.3.9版本，所以。。。

新版创建成功

创建的MavenParent项目中的pom.xml

<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.qhong</groupId>
  <artifactId>MavenParent</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>MavenParent</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>
</project>

现在修改打包方式为pom

  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.qhong</groupId>
  <artifactId>MavenParent</artifactId>
  <packaging>pom</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>MavenParent</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>
</project>

现在在MavenParent文件夹内部再次创建项目Service，不得不说，真慢！

mvn archetype:generate -DgroupId=com.qhong -DartifactId=Service -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

在创建一个Web,

mvn archetype:generate -DgroupId=com.qhong -DartifactId=Web -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

查看MavenParent的pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<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.qhong</groupId>
  <artifactId>MavenParent</artifactId>
  <packaging>pom</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>MavenParent</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>
  <modules>
    <module>Service</module>
    <module>Web</module>
  </modules>
</project>

发现多了modules

现在一个多模块项目就创建好了，MavenParent中的src文件没有用，可以删除了。

用idea打开，查看整个结构：

Service项目的pom.xml

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.qhong</groupId>
    <artifactId>MavenParent</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <groupId>com.qhong</groupId>
  <artifactId>Service</artifactId>
  <version>1.0-SNAPSHOT</version>
  <name>Service</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>
</project>

修改Web的pom.xml，使其依赖Service项目

<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.qhong</groupId>
    <artifactId>MavenParent</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <groupId>com.qhong</groupId>
  <artifactId>Web</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>war</packaging>
  <name>Web 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>

      <artifactId>Service</artifactId>

    </dependency>

  <build>
    <finalName>Web</finalName>

对Service进行安装
