構建自動化定義相關工程項目構建過程當中，在當項目構建成功完成啓動的狀況下，來確保所依賴的項目是穩定的。web

實例

考慮一個團隊正在開發一個項目總線核心API上的其餘兩個項目的應用程序：網頁UI和應用程序的桌面UI的依賴。apache

app-web-ui 項目使用1.0-SNAPSHOT總線核心API項目api

app-desktop-ui 項目使用總線核心API項目 1.0-SNAPSHOTbash

<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>複製代碼

bus-core-api 項目服務器

如今，每當bus-core-api項目的變化時，app-web-ui和app-desktop-ui項目團隊須要本身編譯過程。app

使用快照確保能夠使用最新的 bus-core-api 項目，但要知足上面咱們須要作一些額外的要求。框架

添加一個生成後的目標 bus-core-api POM的應用程序是在 app-web-ui 和 app-desktop-ui 的基礎之上。maven
使用持續集成（CI）的服務器自動管理構建自動化。分佈式

使用Maven

更新總線核心API項目pom.xml工具

<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>複製代碼

讓咱們打開命令控制檯，進入到C: /> MVN > bus-core-api目錄，而後執行如下命令mvn命令。

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

Maven將開始構建項目bus-core-api。
