您能帮我吗，如何克服此错误。

Answer 1

成功构建AOSP代码后，您必须设置DIST_DIR如下：

. build/envsetup.sh && lunch {your_target}
mkdir dist_output
make dist DIST_DIR=dist_output

Answer 2

ota_from_target_files acts different in android 11.

If you have executed "make dist", the otatools is put in out/dist/otatools.zip, or you can "make otatools-package", the otatools will put in out/target/product/ xxxx/otatools.zip。

所有依赖性都包装在otatools.zip中，然后您可以在otatools.zip中使用ota_from_target_files来制作OTA ZIP。

Answer 3

如果您在根目录中执行python脚本ota_from_target_files.py，则需要使用-p来指定路径。

或者

./build/tools/releasetools/ota_from_target_files.py -p out/host/linux-x86 -i PREVIOUS-tardis-target_files.zip dist_output/tardis-target_files.zip incremental_ota_update.zip

，您可以直接从根目录中执行它：

./out/host/linux-x86/bin/ota_from_target_files -i PREVIOUS-tardis-target_files.zip dist_output/tardis-target_files.zip incremental_ota_update.zip

有关详细信息，请参阅构建/工具/reareaseTools/ota_from_target_files.py和build/build/tools/areaseSetools/common.py。

通常，此问题的关键是options.search_path。
