Something is wrong in Eclipse repository (same in Eclipse Kura repository). [message #1760184]

Hi,

I'm new to Kura and I was trying to build a new Maven project adding the latest Kura API jar as dependency (org.eclipse.kura.api-1.1.1.jar), but doing so, I end up with an error saying that "Could not find artifact org.eclipse.kura:kura:pom:2.1.1-SNAPSHOT in Eclipse.repo (https://repo.eclipse.org/content/groups/releases/)".

The problem is the parent of the (release) jar is a snapshot and is not present in the release repository. IMO both should be release or snapshot, not a mix like this.

Using v1.1.0, it works with no error, but I guess I may be missing some features/fixes.

Also it means I'm the first to create a Kura project with Maven since one month ago, is it discouraged to use Maven with Kura ?

Hello,
Compared to 1.1.0, version 1.1.1 has been only annotated with OSGi R6 Semantic Versioning annotations.
For the rest it is identical to 1.1.0 and you will not miss any feature using this version.

But you are right, the parent pom is missing. Version 1.1.1 was deployed separately, to only enable the Kura API baseline verification in CI, but I forgot to update the version and deploy the parent pom.

In the end you can safely use org.eclipse.kura.api v1.1.0.

Regards,
Cristiano

Ok, thanks for your quick answer. Also, my question about the use of Maven for IOT/Kura is not a joke, I'm wondering if it's a common practice to use Maven or if it is clunky and not recommanded because of OSGI, and/or hard to find dependencies ?

For example, here is an extract of my pom.xml trying to re-create dependencies for the "heater" demo project. As you can see, some versions had to be adapted, since they can't be found anywhere, and for "org.eclipse.kura.sun.misc", I just can't find any version anywhere. Should I build Kura jars myself from source ?

After looking into sources (https://github.com/eclipse/kura/tree/develop/target-platform/org.eclipse.kura.camel.sun.misc), it looks like this jar is just fully empty, just an "about.html" file. I wonder why it is still present in github and dependencies.

It looks like my last post has been deleted or maybe I just clicked only on preview and not on post.

About my question on the necessity of building Kura myself, I think it maybe be necessary anyway to get started with Kura since you are not providing javadoc and sources package in your maven repositories like frameworks usually do.

I'm still waiting advice from any user/dev of Kura if it's wise to stay far from Maven when using Kura/OSGI.

The not submitted missing message :

Still about Maven use with Kura and a quite big issue with Eclipse repository, when I try to download javadoc and sources (mvn eclipse:eclipse -DdownloadSources=true -DdownloadJavadocs=true), would be pretty useful to get started with Kura, it says :

       Sources for some artifacts are not available.
       List of artifacts without a source archive:
         o org.eclipse.kura:org.eclipse.kura.api:1.1.0
         o org.eclipse.osgi:org.eclipse.osgi.services:3.3.100.v20120522-1822
         o org.eclipse.osgi:org.eclipse.osgi:3.8.1.v20120830-144521

       Javadoc for some artifacts is not available.
       List of artifacts without a javadoc archive:
         o org.eclipse.kura:org.eclipse.kura.api:1.1.0
         o org.eclipse.osgi:org.eclipse.osgi.services:3.3.100.v20120522-1822
         o org.eclipse.osgi:org.eclipse.osgi:3.8.1.v20120830-144521

And when I browse to https://repo.eclipse.org/content/groups/releases/org/eclipse/kura/org.eclipse.kura.api/1.1.0/, I can confirm sources and javadoc are missing.

Do I have to build all Kura modules myself to get packaged sources and javadocs or are there available somehwere else ?
