Description

Using the plugin's default configuration, its manifest goal produces the following warning:

[INFO] --- maven-bundle-plugin:2.3.6:manifest (default-cli) @ aether-api ---
[WARNING] Manifest org.eclipse.aether:aether-api:jar:0.9.0-SNAPSHOT : Superfluous export-package instructions: [org, org.eclipse]

Note that the mentioned packages contain neither classes nor other resources.

Explicitly setting the plugin configuration like

<configuration>
  <instructions>
    <Export-Package>org.eclipse.aether.*</Export-Package>
  </instructions>
</configuration>

appears to be an effective way to prevent the warning.
