Question

在尝试运行应用时遇到有关app：preDexDebug任务问题的项目存在问题。收到的错误是：

Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

当前设置：

Android Studio 0.8.1
Android Build Tools 20.0.0
Java 1.7_55
Windows 7

即使是默认项目也不会运行，尽管gradle sync构建正常。

Error:Execution failed for task ':app:preDexDebug'.
> com.android.ide.common.internal.LoggedErrorException: Failed to run command:
    C:\...\AppData\Local\Android\android-sdk\build-tools\20.0.0\dx.bat --dex --output C:\...\TestApplication\app\build\intermediates\pre-dexed\debug\support-v4-19.1.0-c0d17b20b65717b1b327ef7ea8fea7e8a443e7fe.jar C:\...\AppData\Local\Android\android-sdk\extras\android\m2repository\com\android\support\support-v4\19.1.0\support-v4-19.1.0.jar
Error Code:
    1
Output:
    Error: Could not create the Java Virtual Machine.
    Error: A fatal exception has occurred. Program will exit.

build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 19
    buildToolsVersion "20.0.0"

    defaultConfig {
        applicationId "com.example.testapplication"
        minSdkVersion 10
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:19.+'
}

Answer 1

通过设置

解决（在Windows上）

set _JAVA_OPTIONS=-Xms512m -Xmx512m -XX:MaxPermSize=256m

现在脚本报告

拿起_JAVA_OPTIONS：-Xms512m -Xmx512m -XX：MaxPermSize = 256m 并且工作正常。

奇怪的是，设置变量GRADLE_OPTS和JAVA_OPTS没有效果。
