Maven Release Plugin deployment of sources.jar and javadoc.jar

I use maven release plugin for generating release of my project. I do not want to generate Javadoc all time I build. On the other hand when I call release:perform I would like if maven would generate sources.jar and javadoc.jar and would deploy it to maven release repository. Just because I am curious how deploying source.jar can be disabled, since It looks like it is deployed by default.

Use the releaseProfiles parameter (example: src,javadoc) to turn on one or more profiles, and in these profiles, define the source and javadoc generation:

<profiles>
    <profile>
        <id>src</id>
        <build>
            <plugins>
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>

                            <phase>verify</phase>
                            <goals>

                            </goals>
                        </execution>
                    </executions>
                </plugin>
            </plugins>
