在Android Studio中使用assembleRelease编译apk时proguardRelease失败

时间：2014-12-18 13:30:52

标签： android-studio proguard

我正在尝试将我的应用程序编译为Android Studio 1.0.1中的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.

该应用程序在调试模式下编译并运行完美，而assembleRelease与Android Studio 0.8一起使用。

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？

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 'se.emilsjolander:StickyScrollViewItems:1.1.0'

    compile 'de.greenrobot:eventbus:2.4.0'
}

错误是

我不得不用

禁用proguard 
minifyEnabled false

不是最好的解决方案，但它确实有效。

Gradle 1.1.0遇到了同样的问题。它记得我移动过的一些旧的类引用，我无法构建apk。

尝试构建＆gt;的清洁

它帮助了我，现在我可以再次构建apk。

将此添加到ProGuard设置文件（如proguard-rules.pro）

-ignorewarnings

我认为你已经解决了你的问题。无论如何，请看这个链接：https://stackoverflow.com/a/29858070/3864698

此修复程序计划用于Gradle Plugin 1.4版。所以我们必须等一下。
