构建自动化定义相关工程项目构建过程中，在当项目构建成功完成启动的情况下，来确保所依赖的项目是稳定的。

实例

考虑一个团队正在开发一个项目总线核心API上的其他两个项目的应用程序：网页UI和应用程序的桌面UI的依赖。

app-web-ui 项目使用1.0-SNAPSHOT总线核心API项目

<project xmlns="http://maven.apache.org/POM/4.0.0" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      </dependency>
   </dependencies>
</project>

app-desktop-ui 项目使用总线核心API项目 1.0-SNAPSHOT

<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>app-desktop-ui</groupId> <artifactId>app-desktop-ui</artifactId> <version>1.0</version> <packaging>jar</packaging> <dependencies> <dependency> <groupId>bus-core-api</groupId> <artifactId>bus-core-api</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> </project>

bus-core-api 项目

<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>bus-core-api</groupId> <artifactId>bus-core-api</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> </project>

现在，每当bus-core-api项目的变化时，app-web-ui和app-desktop-ui项目团队需要自己编译过程。

使用快照确保可以使用最新的 bus-core-api 项目，但要满足上面我们需要做一些额外的要求。

添加一个生成后的目标 bus-core-api POM的应用程序是在 app-web-ui 和 app-desktop-ui 的基础之上。
使用持续集成（CI）的服务器自动管理构建自动化。

使用Maven

更新总线核心API项目pom.xml

<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>bus-core-api</groupId> <artifactId>bus-core-api</artifactId> <version>1.0-SNAPSHOT</version> <packaging>jar</packaging> <build> <plugins> <plugin> <artifactId>maven-invoker-plugin</artifactId> <version>1.6</version> <configuration> <debug>true</debug> <pomIncludes> <pomInclude>app-web-ui/pom.xml</pomInclude> <pomInclude>app-desktop-ui/pom.xml</pomInclude> </pomIncludes> </configuration> <executions> <execution> <id>build</id> <goals> <goal>run</goal> </goals> </execution> </executions> </plugin> </plugins> <build> </project>

让我们打开命令控制台，进入到C: /> MVN > bus-core-api目录，然后执行以下命令mvn命令。

C:/MVN/us-core-api>mvn clean package -U

Maven将开始构建项目bus-core-api。
