Beside the main artifact there can be additional files which are attached to the Maven project. Such attached filed can be recognized and accessed by their classifier.
For example: from the following artifact names, the classifier is be located between the version and extension name of the artifact.
You can deploy the main artifact and the classified artifacts in a single run. Let‘s assume the original filename for the documentation is site.pdf:
mvn org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy-file -Durl=http://localhost:8081/repomanager/ -DrepositoryId=some.id -Dfile=path/to/artifact-name-1.0.jar -DpomFile=path-to-your-pom.xml -Dfiles=path/to/artifact-name-1.0-debug.jar,path/to/site.pdf -Dclassifiers=debug,site -Dtypes=jar,pdf
If you only want to deploy the debug-jar and want to keep the classifier, you can execute the deploy-file like
mvn org.apache.maven.plugins:maven-deploy-plugin:2.8.2:deploy-file -Durl=http://localhost:8081/repomanager/ -DrepositoryId=some.id -Dfile=path-to-your-artifact-jar -DpomFile=path-to-your-pom.xml -Dclassifier=bin
Note: By using the fully qualified path of a goal, you‘re ensured to be using the preferred version of the maven-deploy-plugin. When using mvn deploy:deploy-file its version depends on its specification in the pom or the version of Apache Maven.
