构建项目时出现转换异常[重复]

当我尝试运行我的应用程序时，出现以下错误：

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.transform.api.TransformException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/usr/lib/jvm/java-7-openjdk-amd64/bin/java'' finished with non-zero exit value 3

这是我的应用程序级别build.gradle:

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

    compile('com.crashlytics.sdk.android:crashlytics:2.5.2@aar') {
        transitive = true;
    }
}

这是我的项目级别build.gradle:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

为什么会出现这个错误以及如何解决它？

启用 multidex，它为我解决了问题。

defaultConfig {
multiDexEnabled true
}
