我正在尝试在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.

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

该proguard-rules.pro文件为空.该build.gradle文件和完整的错误如下所示.

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")
    }
}

我正在制作一个新的Android项目,包括标准'app'模块,以及一个库项目(让我们称之为'custom_lib').在app的build.gradle文件,我的链接模块这样:

dependencies {
    compile project(':custom_lib')
}

当我触发构建过程(Menu Build> Make Project)时,我在Gradle控制台中获得以下输出
