Install a JAR to local maven repository

When dependency jars are not available in maven central repository you have to install it to your local repository or you can provide it using system path. Using following command you can send your dependency jar to your local m2 repository.

mvn install:install-file -Dfile=<path/to/your/dependecy/jar> -DgroupId=<groupId> -DartifactId=<artifactId> -Dversion=<version> -Dpackaging=jar


Eg:Let's get google gson library as an example, This is already available in maven repository but here we are going to manually install it to our local m2 repo. Assume i have downloaded gson-2.2.4.jar to my desktop

         <dependency>
             <groupId>com.google.code.gson</groupId>
             <artifactId>gson</artifactId>
             <version>2.2.4</version>
         </dependency>

mvn install:install-file -Dfile=/home/shameera/Desktop/gson-2.2.4.jar -DgroupId=com.google.code.gson -DartifactId=gson -Dversion=2.2.4 -Dpackaging=jar

You will see similar output like below.
