如何修复“构建失败”或“无法加载gradle项目”

Question

我正在制作 javafx应用程序，我想使用gradle将其移植到android软件包（。apk）中，但出现错误。

build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.3.10'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

mainClassName = 'Main.main'
version = '8u40'
dependencies {
    compile fileTree(dir: 'libs', include: '*.jar')

}

jfxmobile {
    downConfig {
        version = '3.7.2'
        // Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
        plugins 'accelerometer', 'audio-recording', 'barcode-scan', 'battery', 'ble', 'browser', 'cache', 'compass', 'connectivity', 'device', 'dialer', 'display', 'in-app-billing', 'lifecycle', 'local-notifications', 'magnetometer', 'orientation', 'pictures', 'position', 'push-notifications', 'runtime-args', 'settings', 'share', 'statusbar', 'storage', 'vibration', 'video'
    }
    android {
        applicationPackage = 'org.javafxports.ensemble'
        compileSdkVersion = 28
    }
    ios {
                infoPList = file('src/ios/Default-Info.plist')
                forceLinkClasses = [
                        'com.gluonapplication.**.*',
                       'com.gluonhq.**.*',
                        'javax.annotations.**.*',
                       'javax.inject.**.*',
                        'javax.json.**.*',
                       'org.glassfish.json.**.*'
               ]
    }
}

这样的错误消息
