Description

From QVTo Bug 582977 and related OCL, MoDisco, QVTd bugs.

The PHP downloads facility provided by Nick Boldt for all modeling projects has become increasingly embarrasing.

• no maintainer
• project decontainerisation
• never updated for Buckminster let alone Tycho
• migration of GIT repos
• change of style breaks framing

and imminently

• discontined EF support for PHP.

Fortunately the new-style downloads page pioneered by EMF is now available using tooling from the JustJ project. See

https://github.com/eclipse/nebula/blob/b4465920c2dbbca0d0ea965f37e9d49c1ccabff1/releng/org.eclipse.nebula.site/promotion/pom.xml#L69-L101

The above were the basis for the MoDisco/OCL/QVTd/QVTo soluition that preserves the separate builder then promoter/publisher architecture.

The existing build changes to

• add justj-promoter.properties to the build-site plugin
• archive the releng/org.eclipse.qvtd.releng.build-site/target/repository/**/*
• change the downstream job to justj-promoter
• remove the buckminster-derived target platform publication
• move the 'interim' and 'release' capabilities, rename/coexist 'stable' as 'milestone'

Thereafter the justj-promoter is a replacement promoter job that runs the pom.xml from a new self-standing releng promoter plugin. NB it needs both Maven capabilitiues and genie authorisation.

(The separate justj-promoter means that a 'release' build is just a repromote of the preceding 'milestone' as a 'release' - no re-build. It also allows the promotion to be easily and reliably disabled while messing around with the main build.)
