Adding local libraries to Maven

How to add user defined .jar files or inhouse developed libraries to Maven Repository, so that my maven project will get executed correctly. Here is the steps I did to add two jar files c:\eg_agent.jar and c:\eg_util.jar to maven repository.

F:\sts-bundle\apache-maven-3.3.9-bin\apache-maven-3.3.9\bin>mvn install:install-file -Dfile=c:\eg_agent.jar -DgroupId=com.eg -DartifactId=agent -Dversion=6.1.2 -Dpackaging=jar

Once it is added to repository, I added the dependency as given below.

<dependency>
<groupId>com.eg</groupId>
<artifactId>agent</artifactId>
<version>6.1.2</version>
</dependency>

Here is another one.

F:\sts-bundle\apache-maven-3.3.9-bin\apache-maven-3.3.9\bin>mvn install:install-file -Dfile=c:\eg_util.jar -DgroupId=com.eg -DartifactId=util -Dversion=6.1.2 -Dpackaging=jar

<dependency>
<groupId>com.eg</groupId>
<artifactId>util</artifactId>
<version>6.1.2</version>
</dependency>
