使用android studio导入之前版本系统的project sync failed 解决办法
Error:(15, 0) Gradle DSL method not found: ‘runProguard()’ Possible causes:

• The project ‘HackerTool’ may be using a version of Gradle that does not contain the method. Open Gradle wrapper file
• The build file may be missing a Gradle plugin. Apply Gradle plugin

-修改 runProguard 为 minifyEnabled 即可

Previous code :
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.txt’
}
}
Current code :
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.txt’
}
}
