3.What is the difference between install and package ?

mvn package just creates the package like jar/ear/war/zip in your target folder.

Syntax: mvn clean package

 

mvn install creates the package like jar/ear/war/zip in your target folder and moves to your local repository

Syntax: mvn clean install

 

mvn install / mvn package itself is enough to perform this, but it is always recommended to perform clean before that to make sure existing things are cleared from target.

 

install command helps us if we have dependent project which needs this particular ear/jar created, then it takes from the local repository.
