用 Maven 编译最简略的 java 程序

用 Maven 编译最简单的 java 程序

参考地址： http://maven.apache.org/guides/getting-started/maven-in-five-minutes.html

下载 Maven 地址：http://maven.apache.org/download.cgi#Installation

设置 Maven 的环境变量： 变量名：M2_HOME   变量值： C:\apache-maven-3.0.5

设置 Path 的环境变量：C:\apache-maven-3.0.5\bin;

建立maven的目录结构，我在这个基础上新增了A.java B.java 和相应的测试类

App.java

package com.xjh.app;

public class App {
	
	public int add(int a, int b) {
		return a + b;
	}
	
}

AppTest.java

package com.xjh.app;

import org.junit.Test;

import junit.framework.Assert;
import junit.framework.TestCase;

public class AppTest extends TestCase {
	
	public void testAdd() {
		App app = new App();
		Assert.assertEquals(3, app.add(1, 2));
		Assert.assertEquals(2, app.add(1, 1));
	}	
	
}

A.java

package com.xjh.app;

public class A {
	
	public int sum(int a, int b) {
		return a + b;
	}
	
}

B.java

package com.xjh.app;

public class B {
	
	public int sub(int a, int b) {
		return a - b;
	}
	
}

ATest.java

package com.xjh.app;

import org.junit.Test;

import junit.framework.Assert;
import junit.framework.TestCase;

public class ATest extends TestCase {
	
	public void testSum() {
		A a = new A();
		Assert.assertEquals(3, a.sum(1, 2));
		Assert.assertEquals(2, a.sum(1, 1));
	}
	
}

BTest.java

package com.xjh.app;

import org.junit.Test;

import junit.framework.Assert;
import junit.framework.TestCase;

public class BTest extends TestCase {
	
	public void testSub() {
		
		B b = new B();
		Assert.assertEquals(4, b.sub(9, 5));
		Assert.assertEquals(-1, b.sub(5, 6));
		
	}
	
}

AllTest.java

package com.xjh.app;

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

public class AllTest {
	
	public static Test suite() {
		TestSuite suite = new TestSuite();
		suite.addTestSuite(ATest.class);
		suite.addTestSuite(BTest.class);
		suite.addTestSuite(AppTest.class);
		
		return suite;
		
	}
	
}

在控制台运行

D:\maven_test\my_app>mvn package

运行结果：
