当我在启用ProGuard的情况下运行项目时出现以下错误：
Warning:Exception while processing task java.io.IOException: proguard.ParseException: Expecting opening '{' at '|' in line 66 of file '/home/pipt/AndroidStudioProjects/gallery/app/proguard-rules.pro'
这是我的应用级build.gradle：

这是我的proguard-rules.pro：
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /home/pipipzz/Android/Sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
# public *;
#}
-dontwarn com.facebook.android.BuildConfig
#Butterknife

我认为错误在ProGuard文件的语法中。我该如何解决这个问题？
修改：如果我删除了proguard-rules.pro的最后两行，那么我会收到有关构建过程的警告以及我的应用崩溃：
