Android Studio - ProGuard "java.io.IOException ...bin\classes (No such file or directory)"
提问by Georgi Angelov
So I am running ProGuard for the first time and I am getting a weird error:
所以我第一次运行 ProGuard，我收到一个奇怪的错误：
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:proguardRelease'.
> java.io.IOException: Can't read [C:\Users\Some\workspace\MyApp\app\bin\classes] (No such file or directory)
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
Here is my gradle:

The Android Gradle plugin already specifies all input and output for you, so you must notspecify -injars, -outjars, or -libraryjars.
Android的摇篮插件已经指定了所有输入和输出你，所以你必须不指定-injars，-outjars或-libraryjars。
Moreover, the file proguard-android.txtin the Android SDK specifies all generic Android settings for you, so you shouldn't specify them again.
此外，proguard-android.txtAndroid SDK 中的文件为您指定了所有通用的 Android 设置，因此您不应再次指定它们。
Essentially, your file proguard-rules.txtcan be empty, except for any application-specific settings to make sure any reflection continues to work.
本质上，您的文件proguard-rules.txt可以为空，但任何特定于应用程序的设置除外，以确保任何反射继续工作。

you no need these lines, because these are already defined.
你不需要这些行，因为它们已经定义好了。
-injars bin/classes
-injars libs
-outjars bin/classes-processed.jar
-libraryjars /usr/local/java/android-sdk/platforms/android-9/android.jar
