config.json把相关子系统裁剪后，编译报错，显示很多组件依赖所裁剪子系统

【问题描述】
我想要裁剪标准系统下的图形子系统、多媒体子系统以及电话子系统，在config.json删除对应子系统配置后，编译报错，如下：

```

看报错像是有些模块依赖于所裁剪的多媒体子系统，这样的话是不是就没有完全解耦，那我想要裁剪相关子系统应该如何做？

有人能帮忙解答下吗

回复 nanfengchuiyeluo: 来了来了

子系统内各部件模块会对外提供功能接口，举例来说，对于DFX子系统，其他子系统都会调用该子系统提供的日志打印能力，这就存在一定的依赖关系，单独裁剪掉DFX子系统则会导致其他子系统编译都报错。因此裁剪掉子系统后，需要将对其有依赖的所有子系统全部裁剪掉

回复 论坛小助手: 那这样的话我就需要把所有依赖的子系统都先梳理出来，然后再裁剪到，如果有些依赖的子系统我不想要裁剪到怎么办呢？就只能把对应子系统引用相关模块的代码给删掉吗？那这裁剪起来也太麻烦了吧，openharmony不是说组件化设计嘛，不应该很容易裁剪嘛

回复 nanfengchuiyeluo: 是都需要裁剪掉。DFX是公共能力
