【问题描述】：
我正在尝试在 Android Studio 1.0.1 中将我的应用程序编译为 assembleRelease 并收到以下消息：
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:proguardRelease'.
> java.io.IOException: Please correct the above warnings first.
应用程序在调试模式下完美编译和运行，并且 assembleRelease 与 Android Studio 0.8 配合使用。
proguard-rules.pro 文件为空。 build.gradle 文件和完整错误如下所示。
有人可以帮忙吗？
build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 19
buildToolsVersion '19.1'
defaultConfig {
applicationId "com.xxx.xxx"
minSdkVersion 15
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
lintOptions {
abortOnError false
absolutePaths false
lintConfig file("lint.xml")
}
}
repositories {
mavenCentral()
flatDir {
dirs 'aars'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.urbanairship:urbanairship-lib:+@aar'

compile 'com.squareup.picasso:picasso:2.4.0'

}
错误是

【问题讨论】：
-
构建输出有许多关于错误引用的警告，尽管它称它们为“警告”，但最终看起来它们是致命错误。
-
@ScottBarta 但它在调试中工作，所以这似乎是proguard的问题，我不知道如何调试。
