Maven

Maven | What is Maven?

Maven:

• project building and configuration tool

• open source

• initially built for Java

  • yet works with many languages

• Challenged by Gradle

  • still, Java’s world reference
  • has put Ant to second place in a few months

• Based on the “convention over config” paradigm

• the build process is based on the project lifecycle:

  • build
  • test
  • deploy
  • install
  • upload
  • …

• a single file describes the project

• for small projects, this file is pretty short and readable

• bigger projects -> bigger pom.xml

Maven | How does it work?

groupid == package
artifactid ==
packaging: type de projet
version (snapshot): permet une update automatique (a mettre en dev)
dependencies: les dependances

• creates artifacts

• stored for further import

• can be of different types:

  • jar (biblioteque)
  • war (archive web, descriptif d’appli web)
  • pom (projet de configuration)
  • …

• manage dependencies:

  • declare the artifacts you need
  • maven will fetch it for you from a central repo
  • add your own repo for your own work to be maven-driven
  • maven will handle transitive dependencies

• dependencies scope:

  • compile
    • default scope
  • provided
  • runtime
  • test

• handle unit testing for you

• very tight integration with frameworks (Junit, TestNG, …)
