I started the LinkedinLearning course Learning Java Enterprise Edition, which uses https://github.com/javaee/cargotracker

So I checked out the cargotracker repo and followed the instructions on the readme file, and ran into an error:

$ mvn package cargo:run
(some dependencies are downlaoded, but then)

So I checked online and saw recommendations to run mvn clean compile – that gave me the same result.

The closest similar issue I found is this github issue: https://github.com/eclipse-ee4j/cargotracker/issues/55

A post there helped me find the dependency in question here: https://download.eclipse.org/rt/eclipselink/maven.repo/org/eclipse/persistence/org.eclipse.persistence.moxy/2.5.0-M13/

So I can download org.eclipse.persistence.moxy-2.5.0-M13.jar, but I don’t know what to do with it.

How can I resolve this error?
