"Deploy" markSlider locally

We need to let Maven know about the proprietary markSlider .jar file. So
we "deploy" it into a repository that lives in the project space itself.
Performed by:

mvn \
-DaltDeploymentRepository=release-repo::default::file:$(pwd)/maven-repo/ \
-Dfile=jars/markSlider.jar -DgroupId=kz.swing -DartifactId=markSlider \
-Dversion=0.1 -DrepoId=release-repo -Durl=file:$(pwd)/maven-repo/ \
deploy:deploy-file
