OpenHarmony如何清理编译

【问题描述】

1. 我希望清理所有编译，然后重新开始编译，我执行了:ccache -C, rm out/ -r 然后重新编译，出现错误：

[OHOS ERROR] Traceback (most recent call last):
[OHOS ERROR]   File "/home/chen/ohos/OpenHarmony_3.2.3_Release/build/lite/hb/__entry__.py", line 89, in main

=====build  error=====

【运行环境】

硬件：RK3568 SDK版本：3.0

重新bash build/prebuilts_download.sh --skip-ssl下

我主要的问题其实是，在添加了驱动服务（驱动LED的GPIO服务）后，编译完成，但是看不到我的驱动服务，后来查找，说是要删除

1. //vendor/hihope/rk3568/hdf_config/khdf/hdf_test/hdf_hcs.hcb
   
2. //out/kernel/vendor/hihope/rk3568/hdf_config/khdf/hdf_test/hdf_hcs_hex.o
   
3. //out//kernel/OBJ/linux-5.10/arch/arm64/boot/Image、Image.lz4
   
4. //out/rk3568/packages/phone/images/boot_linux.img

复制代码

这些文件，我删除后编译，仍然看不到我的驱动服务，而且//vendor/hihope/rk3568/hdf_config/khdf/hdf_test/hdf_hcs.hcb这个也没有重新生成，所以我不清楚什么情况，就想清理掉重新编译
