Where is maven?

How can maven helps on development?

Making build process much easier. Dependency management Centralizing module dependency. Maintaining a standard project layout. Generating report on broken code, broken coding convention, unit test code coverage etc…

Dependency management!

Centralizing module dependency!!

Standard project layout!!

What is maven repository?

Build a sample project

Mavenized terms

What is POM (Project Object Model)? What is artifact? What is group? What is archetype? What is goal? What is dependency?

POM

Goal mvn package mvn compile mvn clean mvn test mvn javadoc:javadoc mvn site …

Dependency <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> </dependencies>

Maven phases

validate generate-sources process-sources generate-resources process-resources compile

Typical goals and usages

Create parent project POM file. Create a new maven project Create a web application module Generate intelliJ IDEA project files Packaging whole project

Create parent project POM file. <?xml version="1.0" encoding="UTF-8"?> <project> <modelVersion>4.0.0</modelVersion><groupId>com.company.project</groupId> <artifactId>project-parent</artifactId><packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <name>project name</name> <modules> <!--module>project-core</module--> </modules> <!-- somewhere in repository --> <repositories> <repository> <id>somewherein</id> <url>http://maven.somewherein.net/</url> </repository> </repositories> <dependencies> <dependency> <artifactId>xom</artifactId> <groupId>xom</groupId> <version>1.1</version> </dependency> </dependencies> </project>

Create a new maven project mvn archetype:create \ –DgroupId=com.company.project \ –DartifactId=project-core

Create a new web application module mvn archetype:create \ –DgroupId=com.company.project \ –DartifactId=project-core \ –DarchetypeArtifactId=maven-archetype-webapp

Generate intelliJ IDEA or eclipse project files mvn idea:idea Or mvn eclipse:eclipse

Packaging whole project mvn install Or mvn package

Configure somewhere repository Go to maven_home/conf/settings.xml Set the following line – <localRepository>\\192.168.1.254\software\24_maven_repository</localRepository>

How to find artifact? Search google – i.e : maven xom Manually browse public repository http://ibiblio.org/maven/ http://repo1.maven.org/maven2/ http://maven.somewherein.net [directory indexing is not enabled]

How to use somewhere in Continuous build server?

Changes on your pom file. <ciManagement> <system>continuum</system> <notifiers> <notifier> <type>mail</type> <configuration> <address>hasan@somewherein.net</address> </configuration> </notifier> </notifiers> </ciManagement> <scm> <connection>svn://host/os/project/trunk/</connection> <developerConnection>svn://somewhereindhaka.net/os/ideabase/idea_content_repo/trunk/development</developerConnection> <tag>HEAD</tag> <url>http://somewhereindhaka.net/os/ideabase/idea_content_repo/trunk/development</url> </scm>

Go to (ask me for url) continuum server url Login using user and password (ask me if you need user and password) Select “maven 2.0+ project” from right side menu. Give your maven pom file url from. i.e – http://host/svn/project/pom.xml

That’s all :D

Thank you every one and those who brought such a nice tool 
