这是build.gradle文件:

buildscript {
    repositories {
        mavenLocal()
        mavenCentral()
        jcenter()
        maven { url "https://plugins.gradle.org/m2/" }
    }
    dependencies {
        classpath 'net.linguica.gradle:maven-settings-plugin:0.5'
        classpath 'org.javafxports:jfxmobile-plugin:1.0.7'
    }
}

plugins {
  id "net.linguica.maven-settings" version "0.5" // make maven settings.xml available in gradle (and automatically setup the security settings for the repos based on the grable name vs maven id
}

apply plugin: 'org.javafxports.jfxmobile'

configurations {
    provided
}

repositories {
    mavenLocal()
    mavenCentral()
    maven { url 'http://oss.sonatype.org/content/groups/public/' }
    jcenter() 
    maven { url 'http://nexus.gluonhq.com/nexus/content/repositories/releases/' }
}

        compileClasspath += configurations.provided
    }
}

    compile ('nl.knowledgeplaza:DH2RIAShared:1.55-SNAPSHOT') {
        exclude module: 'hessian'
    }
    compile 'blog.monkeyboy:hessian-android:1.0'

    compile 'org.jfxtras:jfxtras-controls:8.0-r5-SNAPSHOT'
    compile 'com.miglayout:miglayout-javafx:5.1-SNAPSHOT'

    iosRuntime 'com.gluonhq:charm-ios:2.1.0'
    desktopRuntime 'com.gluonhq:charm-desktop:2.1.0'
}

mainClassName = 'nl.softworks.dh2.dh2fx.DH2FX'

retrolambda {
    defaultMethods true
}

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        packagingOptions {

        }
        dexOptions {

        }
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
    }
}

Answer 1

在 iOS 上部署时，需要使用 forceLinkClasses command ，因此 RoboVM 可以在编译期间链接这些包中包含的类。

您需要在包中包含类，以及您可能使用的任何第三个依赖项上的类:

jfxmobile {
    ios {
        forceLinkClasses = [ 'nl.softwork.**.*', 
                             'com.gluonhq.**.*', 
                             'org.jfxtras.**.*',
                             ...  ]
        infoPList = file('src/ios/Default-Info.plist')
   }
}
