Question

我最近从Android Studio 0.9.2升级到1.0（包括Gradle插件的1.0.0版本），并且我在构建项目时遇到了问题。

每当我构建时，我都会在dexDebug或dexRelease步骤中获得以下异常：

我尝试将Android Studio的堆大小增加到-Xmx4096m，但无济于事。在Android Studio 0.9.2中，版本0.14的gradle插件构建工作正常。

这是我项目的build.gradle文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'
    }
}

这是我模块的build.gradle文件：

apply plugin: 'android'

repositories {
    mavenCentral()
}

dependencies {
    compile 'com.android.support:appcompat-v7:21.+'
    compile 'com.android.support:cardview-v7:21.0.+'
    compile 'com.android.support:recyclerview-v7:21.0.+'
    compile 'com.android.support:multidex:1.+'
    compile 'com.google.android.gms:play-services:6.5.+'
    compile 'org.jsoup:jsoup:1.8.+'
    compile 'commons-io:commons-io:2.4'
    compile 'org.apache.commons:commons-lang3:3.3.2'

    compile 'org.apache.commons:commons-collections4:4.0'
    compile 'com.parse.bolts:bolts-android:1.1.2'
    compile files('libs/android-query.0.26.8.jar')
    compile files('libs/Parse-1.7.1.jar')
}

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.1"
    defaultConfig {
        // Enabling multidex support.
        multiDexEnabled true
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1040009
        versionName "1.4"

    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-dcrapp.txt'
            shrinkResources true
        }

        debug {
            minifyEnabled false
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-dcrapp.txt'
        }
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }


        //Bugfix for Gradle build bug
        packagingOptions {
            exclude 'META-INF/LICENSE.txt'
            exclude 'META-INF/NOTICE.txt'
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

task copyMappingFiles(type: Copy)

copyMappingFiles {
    from 'build\\outputs\\mapping\\release'
    into 'mappings\\'+android.defaultConfig.versionCode
    include('mapping.txt')
}

assembleRelease.finalizedBy copyProguardFiles

这个问题可能是什么原因以及如何解决？

Answer 1

看起来Android Studio内存不足，请尝试在AndroidStudio.app/Contents/bin/studio.vmoptions中增加内存大小

-Xms256m
-Xmx1024m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops

根据Android Studio - How to increase Allocated Heap Size

中的答案建议

此外，您可能想要添加

dexOptions {
    javaMaxHeapSize "4g"
}

根据{{3}}

到您的模块build.gradle

Answer 2

看起来dexing内存不足。尝试：

android {
    dexOptions {
        javaMaxHeapSize "2048M"
    }
}

有关其他选项，请参阅Gradle插件用户指南中的dex options。
