Maven模块聚合与继承

聚合

假如有account-email和account-persist两个模块,我们想要一次构建这两个项目,这时须要用到聚合.

聚合模块

package值必须为pom必须有元素modulesmodule值为相对文件夹名

新建account-aggregator模块,以下有例如以下pom文件,其他两个模块保持不变.

<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.juvenxu.mvnbook.account</groupId> <artifactId>account-aggregator</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>pom</packaging> <name>Account Aggregator</name> <modules> <module>account-email</module> <module>account-persist</module> <module>account-parent</module> </modules> </project>

继承

假如以上两个模块公用一些依赖,你又不想反复这些依赖的配置,能够使用继承.

package值必须为pom子模块必须用元素parent显示声明继承的模块父模块用元素dependencyManagement管理被继承的依赖.

父模块

配置例如以下

<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>com.juvenxu.mvnbook.account</groupId> <artifactId>account-parent</artifactId> <version>1.0.0-SNAPSHOT</version> <packaging>pom</packaging> <name>Account Parent</name> <modules> <module>account-email</module> <module>account-persist</module> </modules> <properties> <springframework.version>2.5.6</springframework.version> <junit.version>4.7</junit.version> </properties> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${springframework.version}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> </dependencies> </dependencyManagement> <build> <pluginManagement> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.5</source> <target>1.5</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> </pluginManagement> </build> </project>
