升级Android Studio 3.1.2 后，ProGuard 配置解析器错误？
After upgrading Android Studio 3.1.2, ProGuard configuration parser error?
我已将 android 工作室从 3.1 升级到 3.1.2。升级工作室后，当我进行构建时 ProGuard 配置解析器错误 发生。我正在为我的项目使用 Dexguard（与 ProGuard 相同）。
规则：
-encryptstrings interface com.jas.digi.Utils.Constant {
public static final java.lang.String *;
}
错误：
ProGuard configuration parser error:
D:\AndroidStudioProjects\project\app\dexguard-project.txt line 41:0
missing EOF at '-encryptstrings'
