Maven Build Lilfe Cycle

 

Maven Build Life cycle :

Once java code is developed > Maven perform below activities

maven  >  takes all java src code >  compile all java files >  .class >  run all classes > test >  build .jar file  >  install .jar in local Repo --> deploy created .jar file into remote repo.

----------------------------------------------------------

A Build Lifecycle is Made Up of Phases

Each of these build lifecycles is defined by a different list of build phases, wherein a build phase represents a stage in the lifecycle.

For example, the default lifecycle comprises of the following phases (for a complete list of the lifecycle phases, refer to the Lifecycle Reference):

------------

Validate

Compile

test

Package

verify

install

deploy

------------

validate - validate the project is correct and all necessary information is available

  validate pom.xml is correct

compile - compile the source code of the project

   target folder 

test - test the compiled source code using a suitable unit testing framework. These tests should not require the code be packaged or deployed

package - take the compiled code and package it in its distributable format, such as a JAR.

verify - run any checks on results of integration tests to ensure quality criteria are met

install - install the package (.jar) into the local repository, for use as a dependency in other projects locally

deploy - done in the build environment, copies the final package to the remote repository for sharing with other developers and projects.

-------

validate -- > check pom.xml is correct or not  or project info is correct

compile --> src/test/java --  compile -->  .class 

test -->  run all .class file -- >  

package --> take compiled class file >     combine/build /package --  into single .jar file 

verify  ->  verifies integrating classes are working fine or not 

install --> install created .jar file into Local repo

deploy -->  it installs created .jar file into Remote repository (Server)

 100 classes -- Dev -developed -  copy  all 100 classes in server ...

  deployment -->   Developer copy ".jar" in server machine (or) remote machine but not 100 java class files
