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
