如何在Gluon Mobile项目中更改jdk？

Question

我已尝试将grade.properties文件夹中.gradle文件中的jdk设置为：org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/bin/java

但是项目仍然使用jdk 8

我在Mac上使用Eclipse，并且还尝试将Eclipse>偏好设置> Java>已安装的JRE中的jdk 9设置为默认值。

如何更改Gluon项目使用的jdk版本？

这是我的build.gradle：

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
        }
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:2.0.28'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

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

mainClassName = 'com.directions.Direction'

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    println JavaVersion.current(); 
    if (JavaVersion.current() == JavaVersion.VERSION_1_9) {
        compile 'com.gluonhq:charm:5.0.0-jdk9'
        androidRuntime 'com.gluonhq:charm:5.0.0'
    } else {
        compile 'com.gluonhq:charm:5.0.0'
    }
    compile 'com.fasterxml.jackson.core:jackson-core:2.7.3'
    compile 'com.fasterxml.jackson.core:jackson-annotations:2.7.3'
    compile 'com.fasterxml.jackson.core:jackson-databind:2.7.3'
    compile 'com.gluonhq:charm:5.0.0'
    compile 'com.google.api-client:google-api-client:1.23.0'
}

jfxmobile {
    downConfig {
        version = '3.8.0'
        // Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
        plugins 'compass', 'display', 'lifecycle', 'magnetometer', 'position', 'settings', 'statusbar', 'storage'
    }
    android {
        manifest = 'src/android/AndroidManifest.xml'
        androidSdk = '/Users/hemma/Library/Android/sdk'
        packagingOptions{
                exclude 'META-INF/LICENSE'
                exclude 'META-INF/LICENSE.txt'
                exclude 'META-INF/NOTICE'
            exclude 'META-INF/NOTICE.txt'
        }
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
        forceLinkClasses = [
                'com.gluonhq.**.*',
                'javax.annotations.**.*',
                'javax.inject.**.*',
                'javax.json.**.*',
                'org.glassfish.json.**.*'
        ]
    }
}

我的gradle.properties看起来像这样：

{\rtf1\ansi\ansicpg1252\cocoartf1561\cocoasubrtf200
{\fonttbl\f0\fswiss\fcharset0 Helvetica;\f1\fnil\fcharset0 Menlo-Regular;\f2\fnil\fcharset0 Monaco;
}
{\colortbl;\red255\green255\blue255;\red0\green0\blue0;\red255\green255\blue255;\red255\green0\blue0;

\f1 \cf2 \cb3 \CocoaLigature0 \
}

从终端运行项目的./gradlew run命令时，构建失败，出现异常Process 'command '/Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1。我将org.gradle.java.home设置为jdk 9还是jdk 10都没有关系。我猜grade.properties看起来不应该像我的吗？

即使我在Eclipse中的Java构建路径设置中删除了jdk 8，也是如此。将Java 8 jre系统库添加到新创建的gluon vm项目中。

gradle.properties文件包含以下内容：

Gluon插件的版本为2.6.0.v20180424-0818，用于Eclipse氧气

Answer 1

org.gradle.java.home必须指向目录。试试：

org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk-9.0.4.jdk/Contents/Home/

Answer 2

我不得不编辑eclipse.ini文件，该文件指向jdk8指向jdk10 bin文件夹。这使我可以与jdk 10一起运行。但是gluon vm项目崩溃了。这是由于它在build.gradle中编译了com.gluonhq：charm：5.0.0。因此，我必须包括jdk 10检查，以便依赖性如下所示

dependencies {
    println JavaVersion.current();
    if (JavaVersion.current() == JavaVersion.VERSION_1_9 || JavaVersion.current() == JavaVersion.VERSION_1_10) {
        compile 'com.gluonhq:charm:5.0.0-jdk9'
        androidRuntime 'com.gluonhq:charm:5.0.0'
    } else {
        compile 'com.gluonhq:charm:5.0.0'
    }
}
