A possible workaround would be the following:
- get the jar first
 - then do it
 
maven plugin dependency:get - pom.xml/project ( , )
mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get -DrepoUrl=https://dtp.intramundi.com/nexus/repository/maven-central/ -Dartifact=<group>:<artifact>:<version>
, , , dependency:copy-dependencies, pom.xml , , .
, a java -cp . yourArtifact.jar .
, , "exec:exec", pom.xml, :
pom.xml,pom.xml , , : , "exec" .
