Classifiers are the additional text given to describe an artifact.
artifact-name-1.0-bin.jar artifact-name-1.0-dev.jar artifact-name-1.0-prod.jar
From the above artifact names, classifiers can be located between the version and extension name of the artifact.
To add classifier into your artifact for your deployment, set the text to the classifier parameter.
mvn deploy:deploy-file -Durl=file://C:\m2-repo \ -DrepositoryId=some.id \ -Dfile=path-to-your-artifact-jar \ -DpomFile=path-to-your-pom.xml \ -Dclassifier=bin
