Class DistributionFlavour

java.lang.Object
com.iizix.server.tools.DistributionFlavour
public final class DistributionFlavour extends Object
The flavour of a distribution (CC-FIX-DIST-NO-ICU, the owner's rulings of 2026-10-14 and 2026-10-23, DN-1 and DN-3): which applications the package carries, and so which installation a package may update.
  • CUSTOMER - ServerAdmin, BIG ACE and the demos: the package every customer gets, iiziServer-distribution-V.B.jar (icu.jar is no longer distributed to customers, 2026-10-14);
  • MINDUS - the customer content plus ICU (apps/icu.jar): Mindus's own servers (BuildUtil/servers), the separately named iiziServer-mindus-distribution-V.B.jar;
  • MLS - ServerAdmin only, no demos: the Mindus License System host (build-MLS-server.ps1).
The mark is the property PROPERTY of RESOURCE inside the server jar lib/com.iizix.standardserver-V.B.jar, beside the version and the build the distribution build stamps there (build-iiziServer-distribution.ps1). A server jar without the property - every package and every installation built before the flavours - counts as CUSTOMER; a value holding $ is the unstamped template of a development run and marks nothing.

The updater refuses a package of another flavour than the installation's (UpdateVerifier), so ICU can neither vanish from a Mindus server through a customer package nor arrive at a customer's through a Mindus package. Nothing here depends on another IIZI class: the updater runs from its own jar.
