Android Studio 1.0 failing build at dexDebug or dexRelease

Question

I recently upgraded from Android Studio 0.9.2 to 1.0 (including version 1.0.0 of the Gradle plugin) and I'm having an issue with building my project.

Whenever I build I get the following exception at the dexDebug or dexRelease step:

I tried increasing the heap size of Android Studio to -Xmx4096m but to no avail. In Android Studio 0.9.2 with version 0.14 of the gradle plugin building worked fine.

This is the build.gradle file of my project:

// 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'
    }
}

And this is the build.gradle file of my module:

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.+'

            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-dcrapp.txt'
        }
    }

    sourceSets {

            java.srcDirs = ['src']

            exclude 'META-INF/NOTICE.txt'
        }

        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

What could be the cause of this issue and how can it be solved?

Answer 1

Looks like dexing runs out of memory. Try:

android {
    dexOptions {
        javaMaxHeapSize "2048M"
    }
}

For additional options, see dex options in the Gradle Plugin User Guide.

Answer 2

Looks like Android Studio ran out of memory, try increasing the memory size in AndroidStudio.app/Contents/bin/studio.vmoptions

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

as per suggested from answers in Android Studio - How to increase Allocated Heap Size

Additionally you may want to add

dexOptions {
    javaMaxHeapSize "4g"
}

to your module build.gradle as per Android Studio Google JAR file causing GC overhead limit exceeded error
