Thanks Hervé for looking into this.
What exactly does "has no file" mean?
It's a regular upload, with jar, javadooc, pom, ....
Just an addendum
With the uploaded ojdbc driver it complains about the following:
[INFO] Generating "Dependencies" report — maven-project-info-reports-plugin:2.4
[ERROR] Artifact: dom4j:dom4j:jar:1.6.1 has no file.
[ERROR] Artifact: javax.transaction:jta:jar:1.1 has no file.
[ERROR] Artifact: stax:stax-api:jar:1.0.1 has no file.
[ERROR] Artifact: xml-apis:xml-apis:jar:1.0.b2 has no file.
[WARNING] The repository url 'http://mycompany.com/nexus/content/groups/public' is invalid - Repository 'nexus' will be blacklisted.
Note that the ojdbc is NOT included?!?
Without the ojdbc, the errors are gone.
Could the temporary nexus-offline warning be a culprit?
Dunno why Maven sees this as offline; it works for everything else so far...
