java - 我不知道我为Gluon Start做错了什么

阿罗哈·盖伊(Aloha Guy)，

我没有任何想法，我从胶粘剂开始就犯错了。

我有intellj IDEA 2018.2.4(社区版)
Build＃IC-182.4505.22，建于2018年9月18日
JRE:1.8.0_152-release-1248-b8 amd64
JVM:JetBrains s.r.o的OpenJDK 64位服务器VM
Windows 10 10.0

install Gluon插件版本:2.7.0

File-> new-> Projekt-> gluon-> Desktop Multi view Projekt with FXML-> java 11-> finish

install gradel Gradle 4.10.2在上次设置 View 中将其用作本地选项

我使用Java版本“11” 2018-09-25

我下载了javaFx11(openjfx-11_windows-x64_bin-sdk)，并在结构中将其用作自由的

知道我有这个->

我会错吗？

最佳答案

Gluon插件2.7.0不久前发布，主要用于使用Java 8创建Gluon Desktop或Gluon Mobile应用程序。

如果现在使用的是Java 11，则在发布新版本的Gluon插件之前，您将不得不更新build.gradle文件。

我建议您看看此guide中如何开始使用JavaFX 11，并检查此question有关将JavaFX 11添加到IntelliJ中的项目的信息。

当您使用Gluon插件时，您将创建一个Gradle项目。为此，您无需下载整个JavaFX SDK，您可以通过Maven Central的依赖项将其包括在内。

因此，编辑您的build.gradle文件，如下所示:

apply plugin: 'java'
apply plugin: 'application'

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

mainClassName = 'com.gluonapplication.GluonDesktop'

dependencies {
    compile 'com.gluonhq:particle:1.1.3'
}

并添加以下更改:

根据Gradle指南，添加一种方法来查找哪个平台:

apply plugin: 'java'
apply plugin: 'application'

def currentOS = org.gradle.internal.os.OperatingSystem.current()
def platform
if (currentOS.isWindows()) {
    platform = 'win'
} else if (currentOS.isLinux()) {
    platform = 'linux'
} else if (currentOS.isMacOsX()) {
    platform = 'mac'
}

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

mainClassName = 'com.gluonapplication.GluonDesktop'

为您的平台添加JavaFX依赖项:

dependencies {
    compile "org.openjfx:javafx-base:11:${platform}"
    compile "org.openjfx:javafx-graphics:11:${platform}"
    compile "org.openjfx:javafx-controls:11:${platform}"
    compile "org.openjfx:javafx-fxml:11:${platform}"

添加与Java 9+兼容的ControlsFX依赖项(默认情况下使用的是Java 8+的8.40.14)，并添加javax.annotation依赖项，它不属于Java 9+:

    compile 'com.gluonhq:particle:1.1.3'
    compile 'org.controlsfx:controlsfx:9.0.0'
    compile 'javax.annotation:javax.annotation-api:1.3.1'
}

根据指南，您需要添加module-path并将所需的模块添加到编译器参数中:

compileJava {
    doFirst {
        options.compilerArgs = [
                '--module-path', classpath.asPath,
                '--add-modules', 'javafx.controls,javafx.fxml'
        ]
    }
}

和运行参数相同。在这种情况下，可以通过--add-exports来访问私有(private)API(由于ControlsFX的某些要求):

run {
    doFirst {
        jvmArgs = [
                '--module-path', classpath.asPath,
                '--add-modules', 'javafx.controls,javafx.fxml',
                '--add-exports', 'javafx.base/com.sun.javafx.runtime=ALL-UNNAMED',
                '--add-exports', 'javafx.graphics/com.sun.javafx.scene=ALL-UNNAMED',
                '--add-exports', 'javafx.graphics/com.sun.javafx.scene.traversal=ALL-UNNAMED',

        ]
    }
}

保存并同步更改，您应该能够运行Gluon Desktop项目。
