在设置了以下值之前，一切都正常:
minifyEnabled true
和
shrinkResources true
但是，在设置这些值后，每当我运行项目时，就会出现以下错误:
Information:Gradle tasks [:app:assembleProdRelease]
Error:path may not be null or empty string. path='null'
Information:BUILD FAILED
Information:Total time: 23.606 secs
Information:1 error
Information:0 warnings
Information:See complete output in console
这个错误的意思是路径不能为空或为空字符串。路径为'null'。 以下是build.gradle文件内容：
signingConfigs {
release {
storeFile file('/home/rishabh/Documents/dekhoJks/release.jks')
storePassword "XXXXXXX"
keyAlias "XXXXXXXX"
keyPassword "XXXXXXXXX"
}
}
buildTypes {
release {
minifyEnabled true
//proguardFiles fileTree(dir: "proguard", include: ["*.pro"]).asList().toArray()
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
shrinkResources true
signingConfig signingConfigs.release
}
}
我尝试将所有可能放入proguard.pro的东西都放进去：

但我仍然无法运行我的应用程序。请问我哪里做错了？
