Maven - 实例-4-依赖传递
这里以Eclipse创建Maven工程来演示。
Setp-1 创建Maven项目
File ---> New ---> Maven Project
---> 默认勾选"Use default Workspace location",点击Next
--->选择maven-archetype-quickstart,点击Next
---> 设置必要的项目参数, 然后点击Finish创建Maven工程
- Group Id : 项目组织的唯一标识符,实际对应JAVA的包结构,一般都是组织域名的反写形式
- Artifact Id : 项目的唯一标识符,实际对应项目的名称,就是项目根目录的名称
- Version : 项目的版本
- Pacaking : 项目的打包方式,默认为jar
这里我们依次建立aaa、bbb、ccc三个Maven项目
<groupId>testDep.AAA</groupId>
<artifactId>aaa</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<groupId>testDep.BBB</groupId>
<artifactId>bbb</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<groupId>testDep.CCC</groupId>
<artifactId>ccc</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
Setp-2 建立依赖
编写pom.xml文件,并建立依赖关系
bbb依赖aaa,ccc依赖bbb : aaa--->bbb--->ccc
aaa
<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">

</dependency>
</dependencies>
</project>
bbb
<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">

</project>
ccc
<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">

<groupId>testDep.CCC</groupId>
<artifactId>ccc</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>

<scope>test</scope>
</dependency>
<dependency>
<groupId>testDep.BBB</groupId>
<artifactId>bbb</artifactId>
<version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>
Setp-3 编译并安装到本地仓库
注意:
需要引入的依赖jar包必须在仓库存在,否则会提示报错。这里通过mvn install安装在本地仓库。
编译aaa:
选中pom.xml文件,鼠标右键Run AS--->Maven build---》在弹出的界面,填写Goals内容:compile,然后Run
如果需要再次运行,可以在填写Goals内容:clean compile,然后Run
安装aaa:
选中pom.xml文件,鼠标右键Run AS--->Maven install

Setp-4 查看依赖传递结果
通过包浏览器可以看到各自的Maven依赖关系。
- bbb依赖aaa,引入了aaa
- ccc依赖bbb,并且通过bbb间接依赖aaa,因此引入了aaa
Setp-5 排除依赖
在ccc项目的pom文件中添加如下内容,来排除aaa的依赖
<exclusions>
<exclusion>
<groupId>testDep.AAA</groupId>
<artifactId>aaa</artifactId>
</exclusion>
</exclusions>
修改pom.xml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/xsd/maven-4.0.0.xsd">

<groupId>testDep.CCC</groupId>
<artifactId>ccc</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>ccc</name>
<url>http://maven.apache.org</url>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>

<scope>test</scope>
</dependency>
<dependency>
<groupId>testDep.BBB</groupId>
<artifactId>bbb</artifactId>
<version>0.0.1-SNAPSHOT</version>
<exclusions>
<exclusion>
<groupId>testDep.AAA</groupId>
<artifactId>aaa</artifactId>
</exclusion>
</exclusions>
</dependency>
</dependencies>
</project>
依赖关系发生改变,不再引入aaa。
