5. Why do we use Maven ? Maven is chiefly used for Java-based projects. The tool helps in building the code downloading dependencies, The tool is used to build and manage any Java-based project. It simplifies the day to day work of Java Developers and helps them in their projects

6. Why do we use Maven ? Maven helps in getting the right JAR files for each project as there may be different versions of separate packages. To download dependencies it is no more needed to visit the official website of each software. It could now be easily done now by visiting “mvnrepository.com”

8. What Is Maven?

9. What Is Maven? • Maven is a popular open-source build tool developed by the Apache Group to build, publish, and deploy several projects at once • Maven is written in Java and is used to build projects written in C#, Scala, Ruby, etc. • The tool is used to build and manage any Java-based project. It simplifies the day to day work of Java Developers and helps them in their projects

It simplifies the day to day work of Java Developers and helps them in their projects

12. What Is Maven? • Maven is based on Project Object Model (POM) and focuses of simplification and standardization of the building process • In the process, it takes care of the following: • Builds • Dependencies • Reports  • Distribution • Releases • Mailing list

13. Maven Repository

14. Maven Repository

15. Maven Repository a • Maven repositories refer to the directories of packaged JAR files that contain metadata. The metadata refers to the POM files relevant to each project. This metadata is what allows Maven to download dependencies • There are three types of repositories: • Local Repository • Remote Repository • Central Repository

16. Local Repository Central Repository Remote Repository Your PC Any server Internet

17. Local Repository Central Repository Remote Repository Local Repository refers to the machine of the developer where all the project material is saved. This repository contains all the dependency jars Your PC Any server Internet

18. Local Repository Central Repository The Remote Repository refers to the repository present on a web server which is used when Maven needs to download dependencies. This repository works same as the Central Repository. Whenever anything is needed from Remote Repository it is first downloaded to the Local Repository ad then it is used Remote Repository Your PC Any server Internet

19. Local Repository Central Repository Remote Repository Central Repository refers to the Maven community that comes into action when there is a need of dependencies, and those dependencies cannot be found in the Local Repository. Maven downloads the dependencies from here in the Local Repository whenever needed Your PC Any server Internet

20. Basic concepts of Maven

21. Basic concepts of Maven

22. Basic concepts of Maven Project Object Model (POM) • Project Object Model (POM) refers to the XML files that have all the information regarding project and configuration details • It has the description of the project, details regarding the versioning and configuration management of the project • The XML file is in the project home directory. Maven searches for the POM in the current directory when any task is to be executed

23. Basic concepts of Maven Project Object Model (POM) • Project Object Model (POM) refers to the XML files that have all the information regarding project and configuration details • It has the description of the project, details regarding the versioning and configuration management of the project • The XML file is in the project home directory. Maven searches for the POM in the current directory when any task is to be executed

Maven searches for the POM in the current directory when any task is to be executed

25. Basic concepts of Maven Dependencies and Repositories • Dependencies refer to the Java libraries that are needed for the project. Repositories refer to the directories of packaged JAR files • If the dependencies are not present in your local repository, then Maven downloads them from a central repository and stores them in the local repository

26. Basic concepts of Maven Dependencies and Repositories • Dependencies refer to the Java libraries that are needed for the project. Repositories refer to the directories of packaged JAR files • If the dependencies are not present in your local repository, then Maven downloads them from a central repository and stores them in the local repository

27. Basic concepts of Maven v Build Life Cycles, Phases and Goals • Build Life Cycles consist of a sequence of build phases, and each build phase consists of a sequence of goals • Each goal is responsible for a particular task • When a phase is run all the goals related to that phase and its plugins are also compiled

28. Basic concepts of Maven v Build Life Cycles, Phases and Goals • Build Life Cycles consist of a sequence of build phases, and each build phase consists of a sequence of goals • Each goal is responsible for a particular task • When a phase is run all the goals related to that phase and its plugins are also compiled

29. Basic concepts of Maven v Build Life Cycles, Phases and Goals • Build Life Cycles consist of a sequence of build phases, and each build phase consists of a sequence of goals • Each goal is responsible for a particular task • When a phase is run all the goals related to that phase and its plugins are also compiled

30. Basic concepts of Maven • Build Profiles refer to the set of configuration values, that are required to build a project using different configurations • Different build profiles are added to the POM files when enabling different builds • A build profile helps in customizing build for different environments Build Profiles

31. Basic concepts of Maven • Build Profiles refer to the set of configuration values, that are required to build a project using different configurations • Different build profiles are added to the POM files when enabling different builds • A build profile helps in customizing build for different environments Build Profiles

33. Basic concepts of Maven • Maven Plugin refers to the group of goals. These goals may or may not be of the same phase • The plugins are used to perform specific goal • Maven has its own standard plugins that can be used. If wanted, we can also implement our own in Java Build Plugins

34. Basic concepts of Maven • Maven Plugin refers to the group of goals. These goals may or may not be of the same phase • The plugins are used to perform specific goal • Maven has its own standard plugins that can be used. If wanted, we can also implement our own in Java Build Plugins

36. Maven Architecture

37. Maven Architecture Pom File Maven Repository Dependencies Read pom.xml Plugins Maven Life cycles Phases and Goals Build profiles

38. Maven Architecture Pom File How does it work: • Read pom.xml file • Download dependencies defined in pom.xml into local repository from central repository • Create and generate a report according to the requirements, and execute life-cycles, phases, goals, plugins etc. Maven Repository Dependencies Read pom.xml Plugins Maven Life cycles Phases and Goals Build profiles

39. Maven Build Lifecycle

40. Maven Build Lifecyle

41. Maven Build Life Cycle • Maven life cycle is a collection of steps that are to be followed to build a project • There are three built-in build life cycles: • Default: handles project deployment • Clean: handles project cleaning • Site: handles the creation of project site’s documentation

42. Compile Maven Build Lifecyle Test-compile Test • Maven lifecycle is a collection of steps that are to be followed to build a project • There are three built-in build lifecycles: • Default: handles project deployment • Clean: handles project cleaning • Site: handles the creation of project site’s documentation Package The Build Life Cycle has different build phases or stages: Integration-test Verify Install Deploy
