Remove distribution profiles from the JClouds parent, main, and core modules. Each profile defines assembly descriptors, but none of those files are provided by the project anymore.
The maven assembly plugin relies on those descriptors to dictate its execution.
The estimation is that individual maven artifacts, one per module, get deployed instead of a compressed deployment unit.
In that case, it is enough to use mavens deploy command in combination with distribution management configuration pushing individual jars to the artifact repositories.
Increase of OSGi dependencies core and compendium (now cmpn) from 4.2 to 6.0.
Previously it was possible to run JClouds in OSGi environments from version 4.
An essential aspect to use JClouds in an OSGi environment requires so-called feature sets. These can be generated manually or automatically - see JClouds-Karaf project. Since there have been significant changes in the structure and behaviour of Karaf in the meantime, an adaptation is appropriate.
Breaking change - probably not, as no other APIs of core and compendium are used than up to now.
OSGi - V4.2 - Karaf 2.2.x - to 2.2.9 (Current Status - not active)
OSGi - V6.0 - Karaf 4.1.x - 4.2 (Current Status - active)
Remove javax libraries inject and annotation. In JDK 8 those libraries are provided by the JDK. Younger JDK versions > 11 exclude them again to make the JDK leaner. Supporting younger JDK versions means integrating more younger libraries maintained by the Jakarta project.
Note: Previously, the maven jar plugin contained a configuration embedded in each module's generated manifest files. The configuration got relocated to the project/bnd.bnd file in a previous commit, and gets handled through the bnd plugin.
In the last commit (last section of squashed commit), the GSON library was integrated into the JClouds core module using maven-bundle plugins include resource instruction. Building OSGi instruction variables from the respective modules show a weakness when resources such as script builder shell scripts are required to be integrated into the bundle but not provide a dedicated variable declaration for the resource section.
The following commit demonstrates a change in strategy in declaration and integration of OSGi metadata.
- Replace old bundle-plugin with newest bnd-plugin (bundle-plugin uses bnd-plugin internally)
- Move OSGi metadata declarations from a maven variable passing strategy into dedicated bnd.bnd files
+ Cleaner pom files, no bundle packaging
+ Intellisense / Autocomplete support for .bnd files in terms of package exports etc.
For demonstration, the overall OSGi adjustments are limited to project, core, script builder, compute, blob store, and load balancer because most custom OSGi metadata is defined here.
Note: Other modules are currently disabled from build because some feedback is needed first.
Make GSON integration work.
To understand the changes, see the core modules' bnd file. GSON internal packages also define a version. Both already exported and new export declarations are fused. The global JClouds core module exports defined the entire set of GSON packages available.
Some minor modifications were made in the module project; replace maven jar plugin with a minified version of the declaration, outsourced in projects bnd file.
Replace substituted GSON package names with those provided from the vendor.
Reduce OSGi-metadata declaration of core-module because the artificial package org.jclouds.json.gson.internal was removed.
Remove the Gson module its children Gson bundle, and Gson shaded.
Remove duplication conflict and check-style rules due to the removal of the internal Gson module.
Add maven repository where a custom version of the Gson library gets hosted, which exports all packages.
Remove particular repository
Remove the declaration of the repository that serves a custom build GSON version. The build uses GSON in its original form of the vendor, which gets distributed through the standard distribution channel. The identifiers for group, artifact, and version correspond to the latest stable release of GSON.
Integrate GSON library in Clouds Core Bundle
The change contained in the commit puts the GSON library into the classpath of the JClouds core module.
After several tests with Karaf and Karaf JClouds, especially if the Maven identifier matches the original GSON library, there are only a limited number of ways to keep the deployment effort low.
Specifically, Karaf has a set of predefined Maven repositories that can be easily customized. The order in which a particular repository is resolved into the customized GSON library is more difficult. In normal OSGi applications, which do not have such a management function, I imagine this configuration to be more complicated. Sure, a unique identifier would help, but then we are back to step 1.
Although I honestly don't like to see this kind of approach in a codebase I'm working with, there are not many alternatives to the main aspect of deployment mentioned above.
Maybe the approach can still ease the problem in the short term. In a further mid-term step, however, this problem must be addressed in general.
Do not export packages matching org.jclouds.json.gson.internal*
because it causes a use constraint violation with OSGi between
jclouds-core and jclouds-gson.

This change reverts commit da4614e and upgrades from Gson 2.3.1 to 2.5,
which is the last version that exports the internal packages, used in
jclouds-core, in the OSGi bundle.
* Improves extension namespace configuration to use Guice multibindings
so each provider can cleanly provide their own namespaces.
* Fixes the HPCloud Compute volume attachment namespace and adds the
corresponding live tests.
* Fixes the Rackspace CloudServers UK volume attachment namespace.
