Android Proguard - 当shrinkResources为true时，构建失败

Question

我正在尝试使用proguard构建项目。如果我使用shrinkResources false它可以正常工作但是当shrinkResources为true且错误

时构建失败

Error:The string "--" is not permitted within comments.
Error:Execution failed for task ':app:packageDebug'.
> !directory.isDirectory()

我检查了字符串＆＃34; - ＆＃34;在整个项目中，我没有找到字符串＆＃34; - ＆＃34;在评论里面。所以我不理解这个错误。

这是我的gradle文件

#When not preverifing in a case-insensitive filing system, such as Windows. Because this tool unpacks your processed jars, you should then use:
-dontusemixedcaseclassnames

#Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
-dontskipnonpubliclibraryclasses

#Preverification is irrelevant for the dex compiler and the Dalvik VM, so we can switch it off with the -dontpreverify option.
-dontpreverify

#Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
-verbose

#The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).
