使用胶子移动插件为JavaFX安卓应用程序构建失败 [英] Build failure for JavaFX android app using the gluon mobile plugin

问题描述

我刚刚用FXML开始了一个新的胶子移动多视图项目，并尝试在更改任何内容之前运行它（除了将build.gradle文件中的jfxmobile-plugin版本从1.2.0更新到1.3.2之外）。它在桌面上工作正常，但当我尝试运行androidinstall gradle任务（连接我的android手机）时它失败了。它给了我以下错误：

 ：mergeClassesIntoJar 
：shrinkMultiDexComponents 
：createMainDexList 
： writeInputListFile 
 [ant：java] Java结果：1 
：dex FAILED 
 
 FAILURE：构建因异常而失败。 
 
 *出了什么问题：
任务执行失败'：dex'。 
> org.gradle.api.GradleException（无错误消息）
 
 *尝试：
使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。 
 
 BUILD FAILED 
  

我的build.gradle文件：

  buildscript {
 repositories {
 jcenter（）
} 
 dependencies {
 classpath 'org.javafxports：jfxmobile-plugin：1.3.2'
} 
} 
 
 apply plugin：'org.javafxports.jfxmobile'
 
 repositories {
 jcenter（）
 maven {
 url'http://nexus.gluonhq.com/nexus/content/repositories/releases'
} 
} 
 
 mainClassName ='com.gluonapplication.GluonApplication'
 
依赖项{
 compile'c​​om.gluonhq：charm：4.2.0'
} 
 
 jfxmobile {
 downConfig {
 version ='3.1.0'
 //不要编辑下面的行。在项目上下文菜单中使用Gluon Mobile Settings而不是
插件'display'，'lifecycle'，'statusbar'，'storage'
} 
 android {
 manifest ='src / android / AndroidManifest.xml'
} 
} 
  

操作系统：Windows 10 。

如果需要任何其他信息来确定问题的原因，请告诉我。谢谢。

解决方案

根据您的日志，我注意到您在64位操作系统上使用32位JDK：

 启动进程'命令'C：\Program Files（x86）\ Java \ _jdk1.8.0_101 \ bin\java.exe ''。工作目录：D：\Android_Projects \ GluonMobile-MultiViewProjectwithFXML命令：C：\Program Files（x86）\ Java \ _ddk1.8.0_101 \bin\java.exe ... 
  

默认情况下，jfxmobile插件 sets Android上的JVM Xmx选项为2 GB，考虑到无法分配的32位操作系统，解决方案是设置较低的值。

基于此行代码，你可以se t：

  android {
 dexOptions {
 javaMaxHeapSize'1g'
} 
} 
  

或者多一点（1.5g左右？）。

请注意，如果使用64位JDK，这将解决。确保相应地更新JAVA_HOME环境变量，因为您不需要减少进程的内存。

I just started a new gluon mobile multi view project with FXML and tried to run it before changing anything (apart from updating the jfxmobile-plugin version in the build.gradle file from 1.2.0 to 1.3.2). it works fine on desktop, but when i try to run the androidinstall gradle task (with my android phone connected) it fails. It gives me the following error:

:mergeClassesIntoJar
:shrinkMultiDexComponents
:createMainDexList
:writeInputListFile
[ant:java] Java Result: 1
:dex FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':dex'.
> org.gradle.api.GradleException (no error message)

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

BUILD FAILED

my build.gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.3.2'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
    maven {
        url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
    }
}

mainClassName = 'com.gluonapplication.GluonApplication'

dependencies {
    compile 'com.gluonhq:charm:4.2.0'
}

jfxmobile {
    downConfig {
        version = '3.1.0'
        // Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
        plugins 'display', 'lifecycle', 'statusbar', 'storage'
    }
    android {
        manifest = 'src/android/AndroidManifest.xml'
    }
}

operating system: Windows 10.

Please let me know if any additional information is needed to determine the cause of the problem. Thank you.

解决方案

Based on your log, I noticed you were using a 32 bits JDK on a 64 bits OS:

Starting process 'command 'C:\Program Files (x86)\Java\jdk1.8.0_101\bin\java.exe''. Working directory: D:\Android_Projects\GluonMobile-MultiViewProjectwithFXML Command: C:\Program Files (x86)\Java\jdk1.8.0_101\bin\java.exe ...

By default, the jfxmobile plugin sets 2 GB for the JVM Xmx option on Android, and considering that on a 32 bits OS that won't be possible to allocate, the solution is setting a lower value.

Based on this line of code, you can set:

android { 
     dexOptions { 
          javaMaxHeapSize '1g' 
     }
}

Or maybe a little bit more (1.5g or so?).

Note that this will be solved if you use a 64 bits JDK. Make sure you update your JAVA_HOME environment variable accordingly, as you won't need to reduce the memory for your process.
