Build
Builds with any one of Maven, Gradle or SBT. The Maven and Gradle builds are best as they will auto-download their own build systems of the correct compatible version for you without you having to pre-install them.
The default build will trigger a Gradle build which requires no pre-installed dependencies other than Java. This is preferred because of the self-bootstrap but the Gradle mechanism additionally has an embedded checksum for security:
make
You can call any one of the 3 major build systems explicitly instead:
Maven:
make mvn
Gradle:
make gradle
SBT:
make sbt
Testing
Continuous Integration is run on this repo to build and unit test it (around 400 JUnit tests).
You can launch tests manually by running this command at the top level of the repo:
make test
Configuration
Strict validations include host/domain/FQDNs using TLDs which are populated from the official IANA list, a snapshot of which is shipped as part of this project.
To update the bundled official IANA TLD list with the latest valid TLDs do
make tld
Custom TLDs
If using bespoke internal domains such as .local, .intranet, .vm, .cloud etc. that aren't part of the official IANA TLD list then this is additionally supported via a custom configuration file in src/main/resources called custom_tlds.txt containing one TLD per line, with support for # comment prefixes. Just add your bespoke internal TLD to the file and it will then pass the host/domain/fqdn validations.
