Java 运行默认Gluon项目后出错（：dex失败）

我下载了用于Netbeans的Gluon插件，将JavaFX应用程序部署到Android上。它在桌面上成功运行，但当我执行

android

任务时，它抛出一个错误：

Executing: gradle :android

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Total time: 4 mins 29.297 secs

这是我的软件配置：

• 我使用了JDK8u45（我还设置了JAVA_HOME的路径）
• 我在IDE中使用了Netbeans 8.0.2
• 我下载了包含API21的Android SDK（我还为Android_HOME设置了路径）
• 我下载了Gradle2.4（我还为GRADLE_HOME设置了路径）
• 我在操作系统中使用了

  windowsxp

  （32位）

该错误的原因是什么？

这是build.gradle：

 buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b9'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

mainClassName = 'com.gluon.GlounMainApp'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
    }
}

这是stacktrace：

我也有同样的问题，现在问题解决了。现在我可以编译并制作我的android apk了

以下是我遵循的步骤

确保已更新sdk管理器->支持库 到了最新版本（23.1.1），这是我发布这篇文章时的最新版本 回答。这将更新

H:\sdk\extras\android\support\multidex文件

确保在build.gradle中添加android sdk位置 androidSdk='H:/ADT BUNDLE/sdk'

像这样

buildscript {
    repositories {
        jcenter()
    }
    dependencies {

           classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b9'


    }
}

apply plugin: 'org.javafxports.jfxmobile'


repositories {
    jcenter()
}

mainClassName = 'com.fff.Fff'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        androidSdk='H:/ADT BUNDLE/sdk'

    }
}

如果您在32位PC中工作

将环境变量名JAVA_选项设置为Xmx1024M

如果您在64位PC中工作

确保安装的JDK是64位而不是32位JDK

@JoséPereda，先生，我使用了胶子插件，但还是发生了错误！怎么了？你的JavaFX项目有任何外部依赖吗？@ItachiUchiha，没有，先生，我没有任何外部依赖。这是一个由Glon插件创建的新项目。@JoséPereda Glon插件自动生成AndroidManifest.xml文件，该文件为应用程序使用一些默认图标@你能试着运行

gradlew--debug android

？它应该打印出实际dex命令本身的输出。这可以让我们更深入地了解命令失败的原因。我已经跟踪了错误：每个默认值的dex命令将Xmx设置为2g。在64位Windows 7上使用32位Java失败。我在gradle.build中的Android块中添加了一个dexOptions，以将其减少到1024m。
