What is a build lifecycle?
A well defined sequence of phases which define the order in which the goals are to be executed.

What happens in the first lifecycle on build lifecycle?
Resource copying can be customized in this phase.
What happens in the compile
Source code compilation is done in this phase.
package
This phase creates the JAR / WAR package as mentioned in packaging in POM.xml.
install
This phase installs the package in local / remote maven repository.
What is a build profile?
A Build profile is a set of configuration values which can be used to set or override default values of Maven build.
Name the three types of build profile
- per project defined in the project POM file
- per user defined in the maven setting xml file
- global defined in the maven global setting xml file
How can you activate the profile?
- Explicitly using command console input.
