mvn release:perform tries to put sources.jar twice to nexus

Question

mvn release perform tries to put sources.jar twice to nexus.
Firstly it puts it with other artifacts (.war, javadoc.jar..).
Then it does bulk deploy and tries to put sources.jar again. Any ideas what is happening ?

maven-deploy-plugin was conflicting with nexus-staging-maven-plugin. I had to put <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-deploy-plugin</artifactId> <configuration> <skip>true</skip> </configuration> </plugin>
