maven打包发布依赖

编译打包之后的class文件中没有注释，这些注释在类文件中是有的！怎么设置可以让编译之后的class文件包含注释？
添加如下pom依赖

<!--生成doc jar包-->
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-javadoc-plugin</artifactId>
    <executions>
        <execution>
            <id>attach-javadocs</id>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>
