build process, uniform building system, quality project management information (such as change Log, cross-reference, mailing lists, dependencies, unit test reports, test coverage reports and many more), guidelines for best practices and transparent migration to new features. To achieve to this goal Maven attempts to deal with several areas like:

• It makes the build process easy
• Provides a uniform building system
• Provides quality related Poject information
• Provides guidelines related to development to meet the best goal.
• Allows transparent migration to new features.

Maven repository Types:

• Public remote
external repository: This public external repository exists at ibiblio.org and maven synchronizes with this repository.

• Private remote
internal repository:

We set up this repository and make changes in the maven's pom.xml or settings.xml file to use this repository.

• Local repository:
This repository is maintained by the developer and stays on the developer's machine. It is

synchronous to the maven repository defined in the settings.xml file that exists in the .m2 directory at its standard location i.e. C:\Documents and Settings\Administrator. If no private internal repository is setup and not listed in the pom.xml or in the setting.xml then the local repository exists on the developer's machine is synchronized with the public maven repository at ibiblio.org.

Advantages of having an internal private repository :

• Reduces conflicts among likelihood versions.
• To build first time it requires less manual intervention.
• Rather than having several separate independent libraries it provides a single central reference repository for all the dependent software libraries.
• It quickly builds the project while using an internal repository as maven artifacts are retrieved from the intranet server rather than retrieving from the server on internet.

Internal private repository of an organisation:

Use cases for maven repository:

• It creates two subrepository inside the
internal repository.

• Downloads ibiblio-cache from ibiblio for artifacts and make it available publically. This synchronizes with external repository from ibiblio.

• internal-maven repository
: used for internal artifacts of an organization. It contains unique artifacts for the organization and is not synchronized with any repository.

• Alternatively, another sub-repository that is not at ibiblio can be created for artifacts. This does not synchronize with any external repository.

• Browse the remote repository by using a web browser.

• Search the artifacts in the repository.

• Download code from version control and make changes in settings.xml to point to the internal repository and build without any manual intervention.

• Install new version of the artifacts.
