Re: [recommenders-dev] [GSOC 2013] SnipEditor Weekly report
Hello Andreas :)
Thanks for the tip, unfortunately it didn't work.
I've set the test/pom.xml like this[1]. As it didn't work, i tried to move the repository and dependency(one by one) to the main .pom file(which looked like this [2]). Afterwards i tried to set the repository in the settings.xml file [3]. I kept getting the following error [4], which turns to [5] if i delete the line in which the repository layout is specified.
Also i set the enable releases and snapshots as i got the following error otherwise:[6]. I haven't managed to reproduce this error again though. I tried to build the repository locally as suggested by the error at [6] but it didn't work. I don't know if i didn't set the .pom files correctly, or there is something wrong somewhere else. Any help is highly appreciated :)
Best regards, Stefan.

OK, this should be unnecessary, as the dependency you rely on is not a
*Maven* plugin (like, e.g., tycho-maven-plugin) but an Eclipse plugin
aka OSGi bundle.

Now, as to the reason why the dependency could not be found, it is
important to know that there are Maven repositories (like Maven central
and p2 repositories). These follow a different format -- and the one at
<http://xtext-utils.eclipselabs.org.codespot.com/git.distribution/releases/unittesting-0.9.x/>
is clearly a p2 repository, as indicated by the plugins/features
folders. (BTW, if you want to compare its structure with that of a Maven
repository, just have a look in your local ~/.m2/repository)

Now, by default Maven assumes that repositories declared through
<repository> have the default (Maven) layout. You have to tell it that
the repository uses the p2 layout. See the Tycho wiki for details [1].

You may also need to add <pomDependencies>consider</pomDependencies> to
your configuration of the target-platform-configuration plugin in
org.eclipse.recommenders.snipeditor.releng/pom.xml [2]. I'm bot entirely
sure about this, though. Maybe you can live without.

Hope that helps.

Andreas
