Referencing Artifacts

Downloading an artifact with the CLI

Attached artifacts can be referenced using the pom.xml’s GAV plus the attached type and classifier. For example, the pom.xml below will install itself as org.aksw.maven4data.examples:attach-example:1.0.0-SNAPSHOT:xml:example:

mvn dependency:copy -D'artifact=org.aksw.maven4data.examples:attach-example:1.0.0-SNAPSHOT:xml:myclassifier' \
  -Dmdep.stripVersion=true -D'outputDirectory=.'

This will create the file attach-example-myclassifier.xml in the local directory. The filename follows the pattern [artifactId]-[classifier].[type].
