Maven GPG Plugin "double singing" artifacts

[Alan D. Cabrera]

I have a root POM that defines are deploy profile that generates source, 
javadoc, and signing.

When I use this profile:

mvn clean install -P deploy

My artifacts get doubly signed, e.g. 

http://oss.sonatype.org/content/repositories/papoose-snapshots/org/papoose/cmpn/papoose-http/1.0-SNAPSHOT/papoose-http-1.0-20100602.142421-2-javadoc.jar.asc.asc

Does anyone know what I am doing wrong?


Regards,
Alan
