在make dist DIST_DIR=mydist編譯OTA包時，遇到個錯誤，在以前android版本中倒是沒有遇到過，這里記錄一下。
報錯內容：

2021-07-02 09:53:29 - common.py - WARNING : Failed to read ODM/build.prop 2021-07-02 09:53:29 - add_img_to_target_files.py - ERROR : ERROR: Traceback (most recent call last):File "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/add_img_to_target_files.py", line 999, in <module>File "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/add_img_to_target_files.py", line 993, in mainFile "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/add_img_to_target_files.py", line 733, in AddImagesToTargetFilesFile "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/common.py", line 701, in LoadInfoDictbuild_info = BuildInfo(d)File "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/common.py", line 393, in __init__self._device = self.GetOemProperty("ro.product.device")File "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/common.py", line 509, in GetOemPropertyreturn self.GetBuildProp(key)File "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/common.py", line 451, in GetBuildPropreturn self._ResolveRoProductBuildProp(prop)File "/home/xxxx/yourdevice_r_1.0_dev_0616/android/out/host/linux-x86/bin/add_img_to_target_files/common.py", line 476, in _ResolveRoProductBuildProp"Invalid ro.product.property_source_order '{}'".format(source_order)) **ExternalError: Invalid ro.product.property_source_order '['odm', 'vendor', 'product', 'product_services', 'system']'**

分析一下對應的common.py代碼吧

common.py腳本def _ResolveRoProductBuildProp(self, prop):default_source_order = self._GetRoProductPropsDefaultSourceOrder()source_order_val = self._GetRawBuildProp("ro.product.property_source_order", None)source_order = source_order_val.split(",")if any([x not in default_source_order for x in source_order]):raise ExternalError("Invalid ro.product.property_source_order '{}'".format(source_order))#掛在這行def _GetRoProductPropsDefaultSourceOrder(self):...return BuildInfo._RO_PRODUCT_PROPS_DEFAULT_SOURCE_ORDER_CURRENT_RO_PRODUCT_PROPS_DEFAULT_SOURCE_ORDER_CURRENT = ["product", "odm", "vendor", "system_ext", "system"]

打開板卡中的systme.prop

ro.product.property_source_order=odm,vendor,product,product_services,system

可以看到這兩者不匹配，導致報錯。
修改一下system.prop中ro.product.property_source_order屬性內容，讓這兩者相等即可，編譯就不再報錯了。

#ro.product.property_source_order=odm,vendor,product,product_services,system ro.product.property_source_order=odm,vendor,product,system_ext,system

總結
