Maven build lifecycles are a series of phases that define the build process of a Maven project.
There are three build lifecycles in Maven:
- default: This is the main build lifecycle in Maven. It includes the following phases:
validate
,compile
,test
,package
,verify
, andinstall
. These phases are executed in order when you run themvn
command with no arguments.
- clean: This lifecycle is used to clean the build directory of a project. It includes the following phases:
pre-clean
,clean
, andpost-clean
.
- site: This lifecycle is used to generate project documentation. It includes the following phases:
pre-site
,site
,post-site
,site-deploy
. Thesite-deploy
phase is optional and is used to deploy the generated documentation to a web server.
Each lifecycle consists of a set of phases, which are executed in order. When you run a specific phase, all previous phases in that lifecycle are also executed. For example, when you run the package
phase in the default lifecycle, the validate
, compile
, and test
phases are also executed.
Here's a brief description of each phase in the default lifecycle:
validate
: validate the project is correct and all necessary information is available
compile
: compile the source code of the project
test
: test the compiled source code using a suitable unit testing framework
package
: take the compiled code and package it in its distributable format, such as a JAR file
verify
: run any checks to verify the package is valid and meets quality criteria
install
: install the package into the local repository, for use as a dependency in other projects
deploy
: copy the final package to the remote repository for sharing with other developers and projects
