Cannot configure Vaadin addons maven repository in Artifactory

Question

I'm trying to configure the Vaadin addons repository in Artifactory, but I always get this error message:

When I change the url to just http://maven.vaadin.com, the connection test succeeds, but the artifacts cannot be resolved. I have other remote repositories configured that work.

Currently I have to resort to downloading and deploying the jar files manually.

Any ideas about what I could be doing wrong here?

Edit: Specific addon example (although all have failed for me, so far):

<dependency>
   <groupId>org.vaadin.addons</groupId>
   <artifactId>loginform</artifactId>
   <version>0.5.2</version>
</dependency>

Answer 1

The test is failing since the Vaadin addons Maven repository does not support directory listing (browsing).
When Artifactory send a test request to the root of the repository it gets a 404 status:

$ curl -vv http://maven.vaadin.com/vaadin-addons/

However you can still use Artifactory to proxy this repository. You will be able to download artifacts from it.
