Build Automation定义了一种方案,一旦项目构建成功完成,相关项目的构建过程就会开始,以确保相关项目稳定。
考虑一个团队正在开发项目 bus-core-api ,另外两个项目 app-web-ui 和 app-desktop-ui 依赖。
app-web-ui 项目正在使用 bus-core-api 项目的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-web-ui</groupId> <artifactId>app-web-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>
app-desktop-ui 项目正在使用 bus-core-api 项目的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> <name>app_desktop_ui</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> <version>3.8.1</version> <scope>test</scope> </dependency> <dependency> <groupId>bus_core_api</groupId> <artifactId>bus_core_api</artifactId> <version>1.0-SNAPSHOT</version> <scope>system</scope> <systemPath>C:\MVN\bus_core_api\target\bus_core_api-1.0-SNAPSHOT.jar</systemPath> </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,app-web-ui和app-desktop-ui项目团队要求每当bus-core-api项目更改时,其构建过程就应该开始。使用快照可确保使用最新的bus-core-api项目,但要满足上述要求,无涯教程需要做一些额外的工作。
使用Maven
更新 bus-core-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>
让无涯教程打开命令控制台,转到C:\> MVN> bus-core-api目录并执行以下mvn命令。
>mvn clean package -U
Maven将开始构建项目 bus-core-api 。

成功构建 bus-core-api 后,Maven将开始构建 app-web-ui 项目。

成功构建 app-web-ui 之后,Maven将开始构建 app-desktop-ui 项目。

使用集成服务
对于开发人员而言,使用CI Server更可取。每次添加新项目(如,app-mobile-ui)作为 bus-core-api上的从属项目时,不需要更新 bus-core-api 项目。 api 项目。 Hudsion是一个用Java编写的持续集成工具,它在servlet容器中,如Apache tomcat和glassfish应用服务器。 Hudson使用Maven依赖性管理自动管理构建自动化。以下快照将定义Hudson工具的角色。
在上面的示例中,当在SVN中更新 bus-core-ui 源代码时,Hudson开始其构建。一旦构建成功,Hudson就会自动查找相关项目,并开始构建 app-web-ui 和 app-desktop-ui 项目。
