maven 子pom如何修改父pom配置

[一达哥]

父pom为只读
其中

<pluginManagement>
            <plugins>
                <!-- Do not deploy -->
                <plugin>
                    <groupId>org.apache.maven.plugins</groupId>
                    <artifactId>maven-deploy-plugin</artifactId>
                    <configuration>
                        <skip>true</skip>
                    </configuration>
                </plugin>
            </plugins>
</pluginManagement>

而我想在子pom中允许deploy
