[cross-project-issues-dev] Orbit and Maven question...
|
David,
You are listed as the lead for Orbit, but the project pages don't appear to have been updated for a while.
I'm wondering if you are still the lead, because I'd like confirmation that Orbit bundles follow a versioning standard where the bundle uses the version of the original jar followed by the build date:
javax.foo.jar (version 1.0.3) -> javax.foo_1.0.3.<date/time built>.jar
My understanding is that this is the case, and that it is followed to easily track the jar that is wrapped (1.0.3), and maintain the ability to fix wrapping bugs (by changing the qualifier:1.0.3.x).
The reason I'm asking is that our team publishes a maven repository for our artifacts, and has for years. A few years ago we added our run-time dependencies (which come from orbit).
At the time there was no coordinated effort to support Maven at Eclipse, and we were fairly new to Maven as well. Since Orbit could release many updated versions of the same bundle:
javax.foo:1.0.3.x
javax.foo:1.0.3.y
javax.foo:1.0.3.z
We had a problem.
Maven standards recognize only a three-part version and qualifier, but there are special rules, so in order to maintain the immutability of a "version" (javax.foo:1.0.3.x) we had to publish Orbit bundles using the qualifier as well. However, opposite of OSGi standards, with Maven a three-part version alone (1.0.3) is always higher than three-part version and qualifier (1.0.3-x) {That meant that 1.0.3 would always supersede 1.0.3-<anything>}. In an attempt to eliminate confusion between versions, we normalized using the four-part Orbit version (1.0.3.x), so we could publish updated Orbit bundles. A side-effect in Maven is that indexing won't work.
I'm wondering if you are aware of any standards Eclipse has adopted for Orbit bundles with the Mavenization projects. We've been asked to migrate to the Eclipse Maven repository, and I want to be sure I don't duplicate effort, and curious at the solution they reached.
