Apache Maven – What is it ? ● A build automation tool ● Mainly for Java projects ● Uses conventions for build structure / procedure ● Licensed by Apache ● Developed via Jakarta project ● Stores libraries and plugins in a central repository www.semtech-solutions.co.nz info@semtech-solutions.co.nz
  • 3. Apache Maven – How does it work ? ● Build controlled via pom.xml project file ● POM = Project Object Model ● Uses standard build order, directories, plugins ● Identifies dependencies in the pom.xml ● One POM can call child POM's ● It makes the build easier ● Provides uniformity www.semtech-solutions.co.nz info@semtech-solutions.co.nz
  • 4. Apache Maven – Why use it ? ● Remove complexity from the build process ● Use a uniform process ● Make the build repeatable ● Make the build consistant with other projects ● Provides a controlled release process ● Manages depedencies www.semtech-solutions.co.nz info@semtech-solutions.co.nz

  • 6. Apache Maven – Usage In terms of usage most estimates seem to agree – Maven / Ant / Eclipse are the most used www.semtech-solutions.co.nz info@semtech-solutions.co.nz
  • 7. Apache Maven – Example Taking the build of hadoop-2.0.6-alpha as an example – A parent pom.xml calls module hadoop-project <modules> <module>hadoop-project</module> <module>hadoop-project-dist</module> <module>hadoop-assemblies</module> – Identifies plugins <plugin> <groupId>com.atlassian.maven.plugins</groupId> <artifactId>maven-clover2-plugin</artifactId> <version>3.0.5</version> </plugin> www.semtech-solutions.co.nz info@semtech-solutions.co.nz
  • 8. Apache Maven – Example Taking the build of hadoop-2.0.6-alpha as an example – A child pom.xml – defines properties <properties> <failIfNoTests>false</failIfNoTests> <maven.test.redirectTestOutputToFile>true</maven.test.redirectTestOutputToFile> – Identifies dependencies <dependency> <groupId>org.mortbay.jetty</groupId> <artifactId>jetty-util</artifactId> <version>6.1.26</version> </dependency> – Defines profiles – Defines plugins – Defines the Build www.semtech-solutions.co.nz info@semtech-solutions.co.nz
