[mvn install] How To install Jar File Into Maven Local Repository?

There are cases that you need to issue Maven’s command to include a jar into the Maven local repository manually:
  1. The jar you want to use doesn’t exist in the Maven center repository.
  2. You created a custom jar, and need to use for another Maven project.
For example,  spring4gwt.jar , a popular third party Java library, which is used to bridge spring and gwt, but it’s not available in the Maven center repository.
In this tutorial, I will show you how to install the “spring4gwt.” jar into your Maven’s local repository.
mvn install:install-file -Dfile=C:\spring4gwt.jar -DartifactId=spring4gwt -Dversion=0.0.1 -Dpackaging=jar
C:\Users\guetampan\bluerock\workspace\mweb-1.0>mvn install:install-file -Dfile=C

e.code -DartifactId=spring4gwt -Dversion=0.0.1 -Dpackaging=jar
