This document provides an overview of Maven, an open-source tool for managing builds, dependencies, documentation, and reporting across Java projects. It defines key Maven concepts like dependencies, plugins, and build lifecycles. It also discusses how Maven supports languages like Java and builds Android projects, and how to add dependencies and plugins to a Maven POM file.

2. Maven defined
 Declarative Dependencies
 External modules
 Build Order
 Directories
 Plug-ins
 Build Management
 Downloads dependencies and maintains local
cache

3. Support
 Languages
 Primarily Java
 C#, Ruby, Scala
 IDEs
 Eclipse, NetBeans, IntelliJ (by default), Jbuilder,
Jdeveloper, MyEclipse…

4. Build Life cycle
 process-resources
 compile
 process-test-resources
 test-compile
 test
 package
 install
 deploy

5.  <modelVersion>4.0.0</modelVersion>
 <groupId>com.project</groupId>
 <artifactId>Project</artifactId>
 <version>1.1</version>
 <packaging>apk</packaging>
 <name>Project-Maven</name>

6.  Dependencies
 Scope
 compile, runtime, test, system, and provided
 System path
 Local path, deprecated
 groupId
 artifactId
 Packaging
 apk, jar, …

7. Tags defined
• A universally unique identifier for a project. It is
normal to use a fully-qualified package name to
distinguish it from other projects with a similar name
(eg. org.apache.maven, com.project)
 The identifier for this artifact that is unique
within the group given by the group ID. An
artifact is something that is either produced or
used by a project. Examples of artifacts
produced by Maven for a project include: JARs,
source and binary distributions, and WARs.
 E.g: android, mockito-all, junit

8. The central repository
 Online central repository which hosts all the
dependencies
 Can search from group-id, artifact-id, version
 Can also download jars, pom, etc

9. How to use?
 POM (pom.xml) file is the main file all the xml data
in it.
 Dependent projects (if any) should also have
pom
 There are 3 major parts:
 Add dependencies
 add dependencies with local path
 add dependencies of custom jars (not in maven)

10. <build>
<plugins> <plugin>
<groupId>com.jayway.maven.plugins.android.generation2
</groupId>
<artifactId>android-maven-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<sdk> <platform>8</platform></sdk>
</configuration>
</plugin> </plugins>
</build>

11. How to add
dependencies<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.10</version>
<scope>test</scope>
</dependency>
</dependencies>

12. Local .jar file
 mvn install:install-file
-DgroupId=com.personagraph
-DartifactId=richinsights
-Dversion=1.4
-Dpackaging=jar -Dfile=libs/AndroidSDK-1.4-
SNAPSHOT.jar

13. cmd
 mvn clean
 mvn test
 mvn compile
 mvn deploy

16. Issues with Andriod
 Maven 3.1.1 is required with Android version 3.8.0
 Google-services aren’t supported
 Create a local jar and include them
