classifier in maven

http://maven.apache.org/plugins/maven-deploy-plugin/examples/deploying-with-classifiers.html

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.

• artifact-name-1.0.jar the main jar which contains classes compiled without debugging information (such as linenumbers)
• artifact-name-1.0-debug.jar the classified jar which contains classes compiled with debugging information, so will be smaller
• artifact-name-1.0-site.pdf a pdf which contains an export of the site documentation.

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.
