  • Jargon depends on Java 1.8+ with a current focus on testing/running under OpenJDK 11
  • Jargon is built using Apache Maven2, see POM for dependencies
  • Jargon supports iRODS current releases, it also maintains very reasonable backwards compatability to iRODS 3.3.1 however this is no longer actively tested
