Maven GPG插件未签名源和Javadoc jar

我正在尝试使用Maven将项目的工件发布到Sonatype.我正在使用Maven GPG插件对构件进行签名，但未对Sonatype所需的源文件和Javadoc jar(仅是主jar)进行签名.我认为这是我pom.xml的相关部分:

I'm attempting to release my project's artifacts to Sonatype using Maven. I'm using the Maven GPG plugin to sign the artifacts, but it's not signing the sources and javadoc jars (just the main jar), which is required by Sonatype. Here's what I think are the relevant parts of my pom.xml:

<plugins>
    ...
    <plugin>
        <artifactId>maven-source-plugin</artifactId>
            <executions>
                <execution>
                    <id>attach-sources</id>
                    <phase>install</phase>
                    <goals>
                        <goal>jar-no-fork</goal>
                    </goals>
                </execution>
            </executions>
    </plugin>
    <plugin>
        <artifactId>maven-javadoc-plugin</artifactId>
        <executions>
            <execution>
                <id>attach-javadocs</id>
                <phase>install</phase>
                <goals>
                    <goal>jar</goal>
                </goals>
                </execution>
        </executions>
    </plugin>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-gpg-plugin</artifactId>
        <executions>
            <execution>
                <id>sign-artifacts</id>
                <phase>verify</phase>
                <goals>
                    <goal>sign</goal>
                </goals>
            </execution>
        </executions>
    </plugin>
    ...
</plugins>

有没有办法告诉它在其他罐子上签名?

Is there any way to tell it to sign these others jars too?
