MAVEN创建多模块的项目

手动构建多模块maven项目,这个simple-parent项目下有两个子模块,一个是jar包型的simple-weather和一个war型的simple-webapp

1.创建一个父的simple-parent项目

D:\>mvn archetype:create -DgroupId=org.sonatype.mavenbook.ch06 -DartifactId=simp

le-parent -DpackageName=org.sonatype.mavenbook -DarchetypeArtifactId=maven-arche

type-webapp

2.修改里面的pom文件如下

<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>org.sonatype.mavenbook.ch06</groupId>

<artifactId>simple-parent</artifactId>

<packaging>pom</packaging>

<version>1.0-SNAPSHOT</version>

<name>simple-parent Maven Webapp</name>

<url>http://maven.apache.org</url>
<modules>

<module>simple-weather</module>

<module>simple-webapp</module>

</modules>

<build>

    <pluginManagement>

    <plugins>

       <plugin>

        <artifactId>maven-compiler-plugin</artifactId>

        <configuration>

         <source>1.5</source>

         <target>1.5</target>

        </configuration>

       </plugin>

    </plugins>

    </pluginManagement>

</build>

<dependencies>

    <dependency>

      <groupId>junit</groupId>

      <artifactId>junit</artifactId>

      <version>3.8.1</version>

      <scope>test</scope>

    </dependency>

</dependencies>

</project>

3.在simple-parent下创建maven子项目是会出错.如下

D:\simple-parent>mvn archetype:create -DgroupId=org.sonatype.mavenbook.weather -

DartifactId=simple-weather

org.apache.maven.reactor.MavenExecutionException: Could not find the model file

'D:\simple-parent\simple-weather\pom.xml'. for project unknown

        at org.apache.maven.DefaultMaven.getProjects(DefaultMaven.java:376)

        at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:289)

        at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:126)

        at org.apache.maven.cli.MavenCli.main(MavenCli.java:282)

        at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

        at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.

java:39)

将这个pom移到别的地方就能正常运行

4.修改simple-weather中的pom文件

<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>
<parent>

    <groupId>org.sonatype.mavenbook.ch06</groupId>

    <artifactId>simple-parent</artifactId>

    <version>1.0</version>

</parent>

<artifactId>simple-weather</artifactId>

<packaging>jar</packaging>

<name>Chapter 6 Simple Weather API</name>

<build>

    <pluginManagement>

      <plugins>

        <plugin>

          <groupId>org.apache.maven.plugins</groupId>

          <artifactId>maven-surefire-plugin</artifactId>

          <configuration>

            <testFailureIgnore>true</testFailureIgnore>

          </configuration>

        </plugin>

      </plugins>

    </pluginManagement> 

</build>

<dependencies>

    <dependency>

      <groupId>log4j</groupId>

      <artifactId>log4j</artifactId>

      <version>1.2.14</version>

    </dependency>

    <dependency>

      <groupId>dom4j</groupId>

      <artifactId>dom4j</artifactId>

      <version>1.6.1</version>

    </dependency>

    <dependency>

      <groupId>jaxen</groupId>

      <artifactId>jaxen</artifactId>

      <version>1.1.1</version>

    </dependency>

    <dependency>

      <groupId>velocity</groupId>

      <artifactId>velocity</artifactId>

      <version>1.5</version>

    </dependency>

    <dependency>

      <groupId>org.apache.commons</groupId>

      <artifactId>commons-io</artifactId>

      <version>1.3.2</version>

      <scope>test</scope>

    </dependency>

</dependencies>

</project>

其它包中的内容直接copy过来

5.创建simple-webapp

D:\simple-parent>mvn archetype:create -DgroupId=org.sonatype.mavenbook.web -Dart

ifactId=simple-webapp -DpackageName=org.sonatype.mavenbook -DarchetypeArtifactId

=maven-archetype-webapp

6.修改simple-webapp中的pom文件

<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>
<parent>

    <groupId>org.sonatype.mavenbook.ch06</groupId>

    <artifactId>simple-parent</artifactId>

    <version>1.0</version>

</parent>

<artifactId>simple-webapp</artifactId>

<packaging>war</packaging>

<name>simple-webapp Maven Webapp</name>

<dependencies>

    <dependency>

      <groupId>org.apache.geronimo.specs</groupId>

      <artifactId>geronimo-servlet_2.4_spec</artifactId>

      <version>1.1.1</version>

    </dependency>

    <dependency>

      <groupId>org.sonatype.mavenbook.ch06</groupId>

      <artifactId>simple-weather</artifactId>

      <version>1.0</version>

    </dependency>

</dependencies>

<build>

    <finalName>simple-webapp</finalName>

    <plugins>

      <plugin>

        <groupId>org.mortbay.jetty</groupId>

        <artifactId>maven-jetty-plugin</artifactId>

      </plugin>

    </plugins>

</build>

</project>

7.从sample中copy包源码与web.xml

8.进入simple-parent中构建多模块项目mvn clean install

9.运行mvn jetty:run

10.可以构建为eclipse项目mvn eclipse:eclipse

11.访问http://localhost:8080/simple-webapp/weather?zip=110
