生成patch报错

只修改2行代码（不涉及资源文件），却发现如下改动，未能生成patch包：

依赖里面有些用到'com.android.support:appcompat-v7:+'这种的，怀疑依赖版本不一致导致的？望解答，谢谢！

Start by reproducing patch generation and trace the reported failure at com.euler.patch.diff.DiffInfo.java:88. Read DexDiffer.java, ApkPatch.java, and Main.java around the listed stack frames, then compare the dependency versions and modified fields involved. Done means the reported two-line code change produces a patch without the RuntimeException.
