java - 我不知道我对 Gluon Start 做错了什么

Question

我不知道我一开始用 Gluon 做错了什么。

1. 我有 IntelliJ IDEA 2018.2.4(社区版)
   版本 #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

2. 安装 Gluon 插件版本:2.7.0

3. 文件->新建->项目->gluon->使用 FXML 的桌面多 View 项目->java 11->完成

4. 安装gradel Gradle 4.10.2 在上次安装 View 中将其用作本地选项

5. 我使用java版本“11”2018-09-25

6. 我下载了 javaFx11 (openjfx-11_windows-x64_bin-sdk) 并将其作为自由在结构中使用

知道我有这个-->

我哪一步出错了？

Answer 1

不久前发布了 Gluon 插件 2.7.0，主要是为了使用 Java 8 创建 Gluon Desktop 或 Gluon Mobile 应用程序。

如果您现在使用的是 Java 11，在 Gluon 插件有新版本之前，您将必须更新 build.gradle 文件。

我建议您在 guide 中了解如何开始使用 JavaFX 11 ，然后检查这个 question关于将 JavaFX 11 添加到 IntelliJ 中的项目。

当您使用 Gluon 插件时，您正在创建一个 Gradle 项目。为此，您不需要下载整个 JavaFX SDK，您可以通过 Maven Central 的依赖项包含它。

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:

1. 根据 Gradle 的指南，添加一种方法来查找您的平台:

   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'
   

2. 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}"
   

3. 添加与 Java 9+ 兼容的 ControlsFX 依赖项(默认情况下使用适用于 Java 8 的 8.40.14)，并添加 javax.annotation 依赖项(该依赖项不是 Java 的一部分) 9+:

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

4. 根据指南，您需要添加模块路径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'
           ]
       }
   }
   

5. 运行参数也是如此。在这种情况下，可以使用 --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，您应该能够运行您的 Gluon Desktop 项目。
