Apache SIS has 3 branches:
* "master" or ("main") depends on the official OGC GeoAPI 3.0.2
release and is the Apache SIS branch that is released.
* "geoapi-3.1" is a branch using a GeoAPI development snapshot taken
from OGC repository.
* "geoapi-4.0" is like "geoapi-3.1" but using a different GeoAPI
development branch.
The "geoapi-3.1/4.0" branches are for testing GeoAPI developments but
are never released.
Problem: "geoapi-3.1/4.0" branches depend on snapshots of GeoAPI
development branches at specific times. Those snapshots are never
released on Maven Central because they are not OGC approved releases.
For building the "geoapi-3.1/4.0" branch of Apache SIS, developers must
first build locally the right GeoAPI branch on a checkout of the same
day. This is very unconvenient, error-prone and make difficult to build
an old commit.
Pull request https://github.com/apache/sis/pull/38 proposes to
automatize the process by adding a git sub-module in Apache SIS
"geoapi-3.1/4.0" branches. This sub-module references directly the OGC
GeoAPI repository at the right commit (identified by the SHA1). "git
pull --recurse-submodules" will automatically pull GeoAPI snapshot at
the right version for the Apache SIS commit. A build of Apache SIS with
gradle will first build GeoAPI (by delegating to Maven because the
GeoAPI project uses Maven) if an only if some GeoAPI interfaces has
changed since the last build. More information there:
https://github.com/apache/sis/tree/geoapi-submodule/geoapi
The proposal has no incidence on Apache SIS "master" (or "main") branch.
That branch will NOT have sub-module and will continue to depend on
GeoAPI 3.0.2 official release only.
I propose to keep the vote open until Friday evening.
