11 ... This library encapsulates a bunch of somewhat complex and commonly used
12 ... Nexus operations into reusable keywords to make writing test suites easier.
14 ... Currently, Java version detection is incorporated so that Java tools can be run reliably.
15 ... Also, suport for installing and running Maven is added, as that needs the Java detection.
16 ... TODO: Move Java detection and Maven to a separate Resource, or rename this Resource.
