Intelligent Projects with Maven - DevFest Istanbul

  • 1. Intelligent Projects with Maven We’ll examine Maven framework with its architecture and create some sample projects! Dev Fest Istanbul December 2014 Mert ÇALIŞKAN @mertcal
  • 2. Mert ÇALIŞKAN • ’02 Hacettepe Graduate • Lecturer @ Hacettepe • 10+ Years of Enterprise Java Experience • Coder @ t2.com.tr • Author • Open Source Software Advocate • Founder of Ankara JUG • Linkedin Profile available @ bit.ly/mertcaliskan
  • 3. My Books Details available at http://amazon.com/author/mert
  • 4. How many of you heard about Maven? Or using it?
  • 5. Maven is… • A project management framework from ASF. • It’s a Uniform Build System. • Making the build as easy as possible. • Comprehensive model for software projects.
  • 7. What Maven provides • Convention over Configuration (konfigurasyon yerine kurallar) • Common Interfaces The time of build engineers is over Stop building the build and focus on development ! • Dependency Management Public repositories • Plugin Architecture • Documentation Generate documentation, reports ...
  • 8. Installing Maven • You need JDK (not the JRE). • Just download the binary from http://maven.apache.org/download.cgi. • Current latest version is 3.2.3. • Open it up to a folder and add it to the path of the OS / Environment Variable.
  • 9. To understand Maven one first need to understand the Project Object Model (POM)
  • 10. POM • It is what makes your project a Maven Project. • It’s an XML file. • Not just for building the project; but also, project’s relationship, list of team members, license, SCM and etc. • Not only for Java projects • you can build FLEX code with appropriate plugins • you can build Microsoft binaries from C# code
  • 11. Anatomy of POM <project ...> <parent /> <groupId /> <artifactId /> <version /> <packaging /> <developers /> <contributors /> <scm>... </scm> <build> <plugins>....</plugins> </build> <dependencies>....</dependencies> <repositories>....</repositories> <pluginRepositories>... </pluginRepositories> <profiles>...</profiles> <reporting>... </reporting> </project>
  • 12. Simplest POM <project> <modelVersion>4.0.0</modelVersion> <groupId>com.devfesttr</groupId> <artifactId>MavenApp</artifactId> <version>1.0.0</version> </project> $ mvn install } compile code run tests package as jar deploy to local repo
  • 13. Simplest POM • GAV (groupid - artifactid - version) is the unique identifier for the project. • They are also called as the coordinates. • groupid: is the identifier for a collection of related modules. It’s more like a hierarchy that starts with the organization and then move on with the specific project group. (com.devfesttr) • artifactid: is the unique identifier or the simple name of the module within a group (MavenApp) • version: identifier for the build number of the project.
  • 14. Question here is How is that possible with 6 lines of XML? Where do I define the source folders, test folders and all other stuff ?
  • 15. Super POM • Same analogy with java.lang.Object • usr/share/Java/maven/lib/maven-model-builder- 3.2.3.jar:org/apache/maven/model/ pom-4.0.0.xml • Standard directory layout • Repo def. for http://repo1.maven.org/maven2 • To see the merged POM: mvn help:effective-pom
  • 16. Let’s create a Maven Project • We’ll be using Eclipse Kepler • IDE for version JavaEE Developers is shipping with Maven Plugins. • We’ll also create a project with the archetype soon.
  • 17. Build LifeCycle • Process for building and distributing an artefact is clearly defined. • 3 built-in Life Cycles default: handles project deployment clean: clean project files generated by a build site: generate project’s site doc. • Each lifecycle consists of phases in specific order. • Zero or more goals attached to each phase.
  • 18. Build LifeCycle default integration-test validate compile test verify install deploy
  • 19. default mvn integration -test validate compile test integration-test verify install deploy mvn phase mvn phase:goal mvn phase phase:goal mvn phase:goal phase:goal validate compile test integration-test
  • 20. Build LifeCycle • validate - validate the project is correct and all necessary information is available • compile - compile the source code of the project • test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed • package - take the compiled code and package it in its distributable format, such as a JAR.
  • 21. Build LifeCycle • integration-test - process and deploy the package if necessary into an environment where integration tests can be run • verify - run any checks to verify the package is valid and meets quality criteria • install - install the package into the local repository, for use as a dependency in other projects locally • deploy - done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.
  • 22. default - full bundle (21 steps) validate Validates whether project is correct and all necessary information is available to complete the build process. initialize Initialises build state, for example set properties. generate-sources Generate any source code to be included in compilation phase. process-sources Process the source code, for example, filter any value. generate-resources Generate resources to be included in the package. process-resources Copy and process the resources into the destination directory, ready for packaging phase. compile Compile the source code of the project. process-classes Post-process the generated files from compilation, for example to do bytecode enhancement/optimization on Java classes. generate-test-sources Generate any test source code to be included in compilation phase. process-test-sources Process the test source code, for example, filter any values. test-compile Compile the test source code into the test destination directory. process-test-classes Process the generated files from test code file compilation.
  • 23. default - cont’d test Run tests using a suitable unit testing framework. prepare-package Perform any operations necessary to prepare a package before the actual packaging. package Take the compiled code and package it in its distributable format, such as a JAR, WAR, or EAR file. pre-integration-test Perform actions required before integration tests are executed. For example, setting up the required environment. integration-test Process and deploy the package if necessary into an environment where integration tests can be run. post-integration-test Perform actions required after integration tests have been executed. For example, cleaning up the environment. verify Run any check-ups to verify the package is valid and meets quality criterias. install Install the package into the local repository, which can be used as a dependency in other projects locally. deploy Copies the final package to the remote repository for sharing with other developers and projects.
  • 24. Dependency Mechanism • It’s where Maven can ease the development when you have hundreds of modules. • You may also depend on external frameworks and maven will fetch them from repositories. • It happens with the Coordinates ! (GAV factor) <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.7</version> <scope>compile</scope> <optional>false</optional> </dependency>
  • 25. Transitive Dependencies • Transitive Dependencies are introduced with Maven version 2.0. • It allows you get the libraries that your own dependencies require and include them automatically. You don’t need to take care of those explicitly. • There is no limit to the number of levels on dependencies.
  • 26. Dependency Exclusion • If projectX depends on projectY and projectY depends on projectZ, the owner of projectX can define an exclusion on projectZ for not to fetch it while fetching projectY. X Y Z
  • 27. Usage of <exclusion> <dependency> <groupId>mycompany</groupId> <artifactId>myproject</artifactId> <version>1.0</version> <exclusions> <exclusion> <groupId>mycompany</groupId> <artifactId>myotherproject</artifactId> </exclusion> </exclusions> </dependency>
  • 28. Optional Dependencies • Let’s say projectY releases itself and mark its dependency on projectZ as optional. When projectX depends on the projectY, project X will only depend on the Y but not the Z. But it may also add the Z as a dependency if needed. X Y Z (optional)
  • 29. Usage of <optional> • ProjectY defines ProjectZ as below with optional dep. <dependency> <groupId>mycompany</groupId> <artifactId>projectZ</artifactId> <version>1.0</version> <optional>true</optional> </dependency>
  • 30. Sample <dependencies> <dependencies> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.1.2.RELEASE</version> </dependency> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>4.3.2.Final</version> </dependency> </dependencies>
  • 31. Scope for Dependencies compile provided runtime test system import CCompile T Classpaths Test R Runtime
  • 32. Scope for Dependencies compile default scope, compile scoped CTR dependencies will be in classpath provided similar to the compile, artefact should be provided by JDK / container @ runtime CT TR runtime not needed for compilation but need @ runtime T test dependency only needed for test compilation & execution CT system same as provided, but artefact should be provided with maven 2.0.9...dependency to be replaced with the dependencies in that POM's <dependencyManagement> section. --- import explicitly with <systemPath /> Classpath
  • 33. Versioning and Ranges <major>.<minor>.<incremental> - <qualifier> 1.2.3 / 1.2.3-alpha-01 Be careful with string comparison, ordering at the qualifiers... 1.2.3-alpha-2 > 1.2.3-alpha-10 (, ) - Exclusive [, ] - Inclusive <version>[3.8 , 4.11)</version> <version>[3.8]</version> Dependency <version>[ , 3.8]</version> Mediation
  • 34. Release and Snapshot Versioning • Snapshot versioning: Used by the projects during development as it implies that the project is still under development and it may change. <version>0.0.2-SNAPSHOT</version> • Release versioning: It’s the versioning that is assumed never to change. Only to be used for a single state of the project when it is released then updated to a next snapshot. <version>0.0.1</version>
  • 35. Archetypes • Templates for Maven projects • Descriptor XML files + Velocity templates • To create a Maven project: mvn archetype:generate -DgroupId=com.devfesttr -DartifactId=sampleApp - Dversion=1.0-SNAPSHOT -DarchetypeGroupId=org.apache.maven.archetypes - DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.0
  • 36. Let’s create a Maven Project with an archetype • By using an archetype from JBOSS repository • https://repository.jboss.org/nexus/content/ repositories/releases/archetype-catalog.xml • We will have Domain classes, Web Pages, in memory database, REST services and etc.

  • 49. Repositories • To manage build artefacts and dependencies • local or remote repositories • Can store jar, war, ear, ejb, rar .... • Maven looks to at least 2 repository if none specified - local one (under user home) - http://repo.maven.apache.org/maven2 (defined in uber-pom) • Release & Snapshot repositories
  • 50. Repositories <repository> <id>jboss-repo</id> <name>The Release JBoss maven repo</name> <url>http://repository.jboss.org/maven2</url> <releases> <enabled>true</enabled> </releases> </repository> <repository> <id>jboss-snapshot-repo</id> <name>The Snapshot JBoss maven repo</name> <url>http://snapshots.jboss.org/maven2</url> <snapshots> <enabled>true</enabled> </snapshots> </repository>
  • 51. Plugins • Plugin-oriented Architecture plugin for even compiling the code.. • A maven artefact w/ descriptor (plugin.xml) and one or more MOJOs • A MOJO is a Maven plain Old Java Object. Each mojo is an executable goal in Maven, and a plugin is a distribution of one or more related MOJOs. • In short, a MOJO is a maven goal, to extend functionality not already found in Maven. • Plexus as its IoC. (Guice also introduced with version 3.x) Why not Spring? • List of plugins supported by Maven Project. https://maven.apache.org/plugins

  • 56. What we did w/ plugins in PrimeFaces • maven-jsf-plugin • Component Class • Tag Handler Class • Declare Component, Tag, Renderer classes in faces-config.xml • Declare facelet tag definition • Declare tld tag definition • plugin available @ http://repository.primefaces.org/org/primefaces/maven-jsf-plugin
  • 57. settings.xml • Maven provides 2 settings file, • Local settings.xml at %USER_HOME%/.m2/settings.xml • Global settings.xml at %M2_HOME%/conf/settings.xml • These files are not bundled with Maven project and don’t get distributed. • If both files exist, their contents get merged. • Local settings.xml overrides the global one.
