在Android Studio中使用assembleRelease编译apk时，proguardRelease失败
我试图在Android Studio 1.0.1中将我的应用程序编译为assembleRelease并获取以下消息：
FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':app:proguardRelease'. > java.io.IOException: Please correct the above warnings first. 该应用程序编译和运行完美的debugging模式，和assembleRelease与Android Studio 0.8工作。
proguard-rules.pro文件是空的。 build.gradle文件和完整的错误如下所示。
任何人都可以帮忙？
的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.google.android.gms:play-services:6.1.+' compile 'me.grantland:autofittextview:0.1.1@aar' compile 'com.google.code.gson:gson:2.2.+' compile 'net.danlew:android.joda:2.3.4@aar' compile 'com.android.support:support-v4:21.0.0' compile 'com.android.support:support-v13:21.0.0' compile 'com.squareup.okio:okio:1.0.0@jar' compile 'net.danlew:android.joda:2.4.0' compile 'de.greenrobot:eventbus:2.2.1' compile 'se.emilsjolander:stickylistheaders:2.5.0' compile 'se.emilsjolander:StickyScrollViewItems:1.1.0' compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.3' compile 'com.sothree.slidinguppanel:library:2.0.2' compile 'com.squareup.okhttp:okhttp:2.1.0' compile 'com.squareup.picasso:picasso:2.4.0' compile 'com.squareup.okhttp:okhttp-urlconnection:2.1.0' compile 'de.greenrobot:eventbus:2.4.0' }

将其添加到ProGuard设置文件（如proguard-rules.pro）
-dontwarn okio.**
我不得不禁用proguard
minifyEnabled false
不是最好的解决scheme，但它的工作原理。
我遇到了Gradle 1.1.0的问题。 它记得我已经移动了一些旧的类引用，我无法构buildapk。
尝试构build > 清洁 。
它帮助了我，现在我可以再次构buildapk。
我想你已经解决了你的问题。 无论如何看到这个链接： https : //stackoverflow.com/a/29858070/3864698
该修补程序计划用于Gradle插件版本1.4。 所以我们必须等一下。
