In the maven instructions for the maven-bundle-plugin:
{code:java}
<_bundleannotations></_bundleannotations>{code}
This will disable annotation scanning for _all_ classes.
Ran into the same issue when using apache-poi, which includes log4j:

> with:
> {code}
> [ERROR] Bundle
> org.apache.karaf.shell:org.apache.karaf.shell.core:bundle:4.2.3-SNAPSHOT :
> The Bundle-Activator header only supports a single type. The following types
> were found:
> org.apache.karaf.shell.impl.console.osgi.Activator,org.apache.felix.gogo.jline.Activator.
> This usually happens when a macro resolves to multiple types
> [ERROR] Error(s) found in bundle configuration
> {code}
> [~rotty3000] do you know a workaround in the {{maven-bundle-plugin}} about
> that ? If not, do you mind if I remove {{@Header}} from Gogo JLine Activator ?
> Thanks.
