Asking for help (advanced level of programming needed )

Wondering if I can ask for help with getting Maven to build the .jar files.  Following' link above, we need to add 2x 3rd party jars to get emails up and running on the back end.

I added the jars in a lib file.  Then told maven to install and updated the pom file (following https://stackoverflow.com/questions/396245/add-a-dependency-in-maven ).  I still don't see .class files for either though

How do I take a jar file that I have and add it to the dependency system in maven 2? I will be the maintainer of this dependency and my code needs this jar in the class path so that it will compile.

I committed to my repo the changes to the pom file (2 added dependencies) -- https://github.com/fafnix/mainBuild/blob/master/pom.xml

Also, here are the install commands (also tried mvn clean install).  I double checked the version number (head of the unzipped files -- https://stackoverflow.com/questions/5834794/how-to-check-the-version-of-jar-file) and mvnrepository has the dependency format (https://mvnrepository.com/artifact/javax.activation/activation/1.0.2):

mvn install:install-file -Dfile=lib/mail.jar -DgroupId=javax.mail -DartifactId=mail -Dversion=1.4.3

mvn install:install-file -Dfile=lib/activation.jar -DgroupId=javax.activation -DartifactId=activation -Dversion=1.0.2 -Dpackaging=jar
