Hi

Building OpenHAB from the default repository, got this exception running mvn install. Any idea about the origin of the problem?

TIAFYH

Hi,

Who is Obelix? Your local Nexus?

Caused by: org.sonatype.aether.transfer.ArtifactNotFoundException: Could not find artifact org.fornax.toolsupport:fornax-oaw-m2-plug
in:pom:3.3.0 in nexus (http://obelix:8080/nexus-2.2-01/content/groups/public)

I assume that you need to configure some more remote repos in your Nexus - note that the parent pom.xml of openHAB defines:

          <pluginRepository>

            <id>fornax.repository</id>

            <name>Fornax Repository</name>

            <url>http://www.fornax-platform.org/m2/repository</url>

            <snapshots>

                <enabled>true</enabled>

            </snapshots>

          </pluginRepository>

so that's where you will find the required plugin. Add this location to your Nexus and it should work.

Regards,

Kai

Hi

yes obelix is my local nexus... I already added the fornax repository as you mention in your response and I got the same error:
Could not find artifact org.fornax.toolsupport:fornax-oaw-m2-plugin:pom:3.3.0 in nexus (http://obelix:8080/nexus-2.2-01/content/groups/public) -> [Help 1]

And effectively, the pom.xml is not there... see the scren capture.. there is only the jar... so I am a little bit puzzled..

Hi Again

My local nexus repository has blocked the fornax repository as

Hi Kai

For your information, I fixed this issue by deleting the local nexus fornax directory and recreate a new one with this repository URL:

http://www.fornax-platform.org/nexus/content/groups/public/

Rgds

Hi,

Thanks for your analysis. It seems that the fornax repository url is outdated - so I have just changed the openHAB pom.xml to use the new one that you have successfully tested.

Best regards,

Kai

Grüezi - thank you for having posted this information publicly here on your list - it was useful to me in a completely different context, to resolve a "hostname in certificate didn't match: <fornax.itemis.de> != <projects.itemis.de> OR <projects.itemis.de>" +  Access denied to: http://projects.itemis.de/nexus/content/repositories/public/ error on an (OpenHAB unrelated) project https://travis-ci.org/vorburger/eLang/builds/27756746. 

The correct working URL today is: https://projects.itemis.de/nexus/content/groups/public/ (note they only seem to allow https not http, and only /groups/ is public, not /repositories/ in case anyone Googling this hits is in the future).

PS: For new projects, one would want to use https://www.eclipse.org/Xtext/documentation.html#continuousIntegration (==> https://github.com/svenefftinge/maven-xtext-example)

Hi Michael,

I am glad that we were of help!

> useful to me in a completely different context

It’s a pity that you are working on completely other projects than ours ;-)

Have fun,

Kai
