android-studio之在 Android Studio 中使用 assembleRelease 编译 apk 时 proguardRelease FAILED

2024年04月18日9www_RR

我尝试在 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. 

该应用程序在 Debug模式下编译和运行完美,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' 
    } 
}

    compile fileTree(dir: 'libs', include: ['*.jar'])
