Often times you will have 3rd party JARs that you need to put in your local repository for use in your builds. The JARs must be placed in the local repository in the correct place in order for it to be correctly picked up by Maven.

To install a JAR in the local repository use the following command:
mvn install:install-file -Dfile=<path-to-file> -DgroupId=<group-id> \
-DartifactId=<artifact-id> -Dversion=<version> -Dpackaging=<packaging>
