在类路径上找不到/javafx.platform.properties

Question

上个月，我为android mobile构建了许多gluon应用程序。他们正在工作。但是现在当我使用相同的方式构建apk时它们无法正常工作，并在android mobile上生成此错误 Unfortunately GluonSingleViewApp has stopped. 我在这个问题上搜索了大约两个星期，但没有找到任何解决方案。现在我需要您的帮助社区。

在建立了包括gluon提供的示例，netbeans gluon示例项目和falilure在内的许多项目之后，我遵循了简单的方法。

在netbeans中，我制作了一个简单的新GluonSingleView应用，然后应用task> android> androidInstall。

当我在移动设备上运行应用程序时显示错误 Unfortunately GluonSingleViewApp has stopped.

我没有更改我的gradle.build文件中的任何内容。

  buildscript {
      repositories {
          jcenter()
      }
      dependencies {
          classpath 'org.javafxports:jfxmobile-plugin:1.3.12'
      }
  }

  apply plugin: 'org.javafxports.jfxmobile'

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

  mainClassName = 'com.gluonsingleviewapp.GluonSingleViewApp'

  dependencies {
      compile 'com.gluonhq:charm:5.0.0'
  }

  jfxmobile {
      downConfig {
          version = '3.8.0'
          // 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'
      }
  }

这是Android Monitor生成的LogCat
