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>

         <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>

         <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。

automated build


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。
