apkpatch工具 生成的patch文件夹里 smali为空，diff.dex也不合法？

E:\hotfix\apkpatch-1.0.3\apkpatch.bat -f E:\hotfix\example\noBug.apk -t E:\hotfix\example\bug.apk -o out.apatch -k E:\hotfix\example\mydebug.keystore -p android -a ppp.keysto re -e android
然后也没有“modified”的输出；
生成的patch文件夹里 smali为空，diff.dex也不合法，这是怎么回事呢？

Start with the apkpatch.bat command shown in the report and reproduce it using the referenced APKs and keystore. Inspect the generated patch folder, especially the empty smali directory and diff.dex, and compare the command arguments with the expected apkpatch invocation. Done means identifying why no “modified” output is produced and generating a valid patch.
