I am trying to use HiveUDFs from: https://github.com/petrabarus/HiveUDFs. I downloaded the UDFs, opened a Cygwin terminal, changed directory (cd) to the folder with the pom.xml, then ran mvn. It gave errors, which I addressed by editing the pom.xml per the instructions in the first answer in Maven 3 warnings about build.plugins.plugin.version.
I am still getting the following errors and am unable to resolve them despite Googling.
$ mvn -e
