Maven - 实例-1-手工创建Maven项目
1- 根据包结构创建maven项目目录
TestMaven
- src
- src/main/java/anliven/testmaven01/HelloMaven.java
- src/test/java/anliven/testmanven01/HelloMavenTest.java
- pom.xml
2- 示例代码和pom文件
<groupId></groupId> ：项目的包名
<artifactId></artifactId> ： 模块名
<version></version> ： 版本，遵循Maven版本管理规范
HelloMaven.java
package anliven.testmaven01;
public class HelloMaven {
public String sayHello() {
return "Hello Maven!";
}
}
HelloMavenTest.java
package anliven.testmaven01;
import org.junit.*;
import org.junit.Assert.*;
public class HelloMavenTest {
@Test
public void testMaven() {
System.out.println("Run test!");
Assert.assertEquals("Hello Maven!", new HelloMaven().sayHello());
}
}
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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>anliven.testmaven01</groupId>
<artifactId>testmaven</artifactId>
<version>0.0.1-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
</dependency>
</dependencies>
</project>
3- 运行mvn compile
如果是第一次运行mvn compile等命令时，将会下载很多的第三方和maven所依赖的jar包。
在Maven项目根目录下，默认生成target目录：
target 构建过程中的默认生成的临时目录
target/classes/ 存放src/main/java目录下源文件编译出来的字节码文件（.class）
target/maven-status/

4- 运行mvn test
生成如下目录：
target/surefire-reports/ 存放生成的测试报告
target/test-classes/ 存放src/test/java目录下源文件编译出来的字节码文件（.class）
