Fixes dependencies to make it possible to build SIP-Creator (replacing a dependency which was on a repo that is no longer available) and upgrades dependencies, particularly Groovy, to be able to run SIP-Creator on JDK 11 and 17 as well as 8.
On JDK 17 it is required, and on 11 optional, to add the following on the java command line: "--add-opens java.base/java.util=ALL-UNNAMED". See the XStream FAQ.
