I still get this error:
[ERROR] Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failure to find org.apache.maven.plugins:maven-resources-plugin
:jar:2.6 in http://it-nexus.myDomain:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of
nexus has elapsed or updates are forced -> [Help 1]
and this has to do with this mirror configuration:
<mirrors>
<mirror>
<id>nexus</id>
<name>Nexus Public Mirror</name>
<url>http://it-nexus.myDomain:8081/nexus/content/groups/public</url>
<mirrorOf>central</mirrorOf>
</mirror>
</mirrors>
It is not clear for me how to configure the mirrors in that way that I can upload my Artefacts with mvn deploy.
It seams to me that Maven looks up for plugin- artefacts at my plain Nexus- Server. In my opinion it should be cascaded in that way that if artefacts are not available in my local nexus that it should be looked up in central. How to do that?
