Maven创建项目

Maven教程 - Maven创建项目

在本章中，我们将使用Maven插件来创建一个新项目。创建一个Maven项目后，我们将添加一些Java源代码。

Maven使用 archetype 和 maven-archetype-quickstart 插件插件来创建项目。

在 C:\\ mvn_test 文件夹中转到并执行以下mvn命令。

C:\mvn_test>mvn archetype:generate -DgroupId=com.java2s.ide -DartifactId=xmlFileEditor -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

这里是输出。

c:\mvn_test>mvn archetype:generate -DgroupId=com.java2s.ide -DartifactId=xmlFileEditor -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

Maven生成的文件夹。

它还为我们创建了两个源文件，一个使用main方法另一个是单元测试用例。

package com.java2s.ide;

/**
 * Hello world!
 *
 */
public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
    }
}

Maven还为生成的应用程序创建了测试用例。

package com.java2s.ide;

import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;

/**
 * Unit test for simple App.
 */
public class AppTest 
    extends TestCase
{
    /**
     * Create the test case
     *
     * @param testName name of the test case
     */
    public AppTest( String testName )
    {
        super( testName );
    }

    /**
     * @return the suite of tests being tested
     */
    public static Test suite()
    {
        return new TestSuite( AppTest.class );
    }

    /**
     * Rigourous Test :-)
     */
    public void testApp()
    {
        assertTrue( true );
    }
}

生成的pom.xml文件如下所示。

<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.java2s.ide</groupId>
  <artifactId>xmlFileEditor</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>xmlFileEditor</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>

注意

Maven已经添加了Junit作为测试框架。默认情况下，Maven添加一个源文件 App.java 和在其默认目录结构中的测试文件 AppTest.java 。
