JavaFXPorts MySqlDB-Driver 包含在项目 :dex error 中

Question

我想创建一个使用 MySqlDB 连接的应用程序/桌面应用程序。我在 Netbeans 中使用了 Gluon 插件。当我想编译桌面应用程序时，一切正常。但是当我想编译 Android 应用程序时 -> 它崩溃了

信息:JDK:8u65
Netbean版本:8.0.2

这是 build.gradle:

谢谢，希望你能帮助我。

Answer 1

我尝试使用最新的 mysql-connector 驱动程序 (5.1.37)，并且在构建 apk 时遇到了相同的异常。

此异常似乎与用于编译 driver 的 JDK 的一些问题有关。 ，而不是 Android 不支持 mysql。

所以按照这个answer在那篇文章中，我使用了旧版本的驱动程序:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.6'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

dependencies {
    compile 'mysql:mysql-connector-java:3.1.12'
}

mainClassName = 'com.gluonhq.testsql.TestSQL'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        packagingOptions {
            exclude 'META-INF/INDEX.LIST'
        }
    }
    ios {
        forceLinkClasses = [ 'com.gluonhq.**.*', 'com.mysql.**.*']
        infoPList = file('src/ios/Default-Info.plist')
    }
}

我能够构建该项目并在桌面、Android 和 iOS 上成功运行它。

编辑

对于 iOS，使用较新版本的驱动程序 (3.1.13+) 会导致编码 exceptions 。
