在 Gradle 中使用 SWT 无法解决所有依赖项

Question

我正在尝试在我的 Gradle 项目中使用最新的 Eclipse SWT 3.114.0，但得到以下结果：

   > Could not find org.eclipse.platform:org.eclipse.swt.${osgi.platform}:3.114.0.
     Searched in the following locations:
       - https://jcenter.bintray.com/org/eclipse/platform/org.eclipse.swt.${osgi.platform}/3.114.0/org.eclipse.swt.${osgi.platform}-3.114.0.pom
       - https://repo.maven.apache.org/maven2/org/eclipse/platform/org.eclipse.swt.${osgi.platform}/3.114.0/org.eclipse.swt.${osgi.platform}-3.114.0.pom
       - file:/C:/Users/voark/IdeaProjects/Eden-Dev/newlauncher/libs/org.eclipse.swt.${osgi.platform}-3.114.0.jar
       - file:/C:/Users/voark/IdeaProjects/Eden-Dev/newlauncher/libs/org.eclipse.swt.${osgi.platform}.jar
       - https://jcenter.bintray.com/org/eclipse/swt/org/eclipse/platform/org.eclipse.swt.${osgi.platform}/3.114.0/org.eclipse.swt.${osgi.platform}-3.114.0.pom
     Required by:
         project : > org.eclipse.platform:org.eclipse.swt:3.114.0

Possible solution:
 - Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html

这是我的build.gradle：

import org.gradle.api.JavaVersion

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.github.jengelman.gradle.plugins:shadow:5.2.0'
    }
}

apply plugin: 'java'
apply plugin: 'idea'
apply plugin: 'application'
apply plugin: 'com.github.johnrengelman.shadow'

mainClassName = 'com.legacypk.newlauncher.Main'

group 'com.legacypk'
version '1.0.0'

sourceCompatibility = JavaVersion.VERSION_1_8
targetCompatibility = JavaVersion.VERSION_1_8

repositories {
    jcenter()
    mavenCentral()
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    compile group: 'org.eclipse.platform', name: 'org.eclipse.swt.win32.win32.x86_64', version: '3.114.0'
    compile group: 'org.eclipse.platform', name: 'org.eclipse.swt.cocoa.macosx.x86_64', version: '3.114.0'
    compile group: 'org.eclipse.platform', name: 'org.eclipse.swt.gtk.linux.x86_64', version: '3.114.0'
    compile group: 'org.eclipse.platform', name: 'org.eclipse.swt.gtk.linux.ppc64le', version: '3.114.0'

    compile name: 'DJNativeSwing'
    compile name: 'DJNativeSwing-SWT'
}

我在这里错过了什么？

首先，SWT 现已在 Maven Central 上正式发布，因此您可能应该将 mavenCentral() 添加到您的存储库块中。

其次，maven 属性osgi.platform 似乎没有被 gradle 处理。相反，您必须做一些特殊的依赖关系解析才能正确获取平台特定的依赖关系。

以下应该可以正常工作（来自https://github.com/LWJGLX/lwjgl3-swt/blob/master/build.gradle）

configurations.all {
    resolutionStrategy {
        dependencySubstitution {
            def os = System.getProperty("os.name").toLowerCase()
            if (os.contains("windows")) {
                substitute module('org.eclipse.platform:org.eclipse.swt.${osgi.platform}') with module("org.eclipse.platform:org.eclipse.swt.win32.win32.x86_64:3.114.0")
            }
            else if (os.contains("linux")) {
                substitute module('org.eclipse.platform:org.eclipse.swt.${osgi.platform}') with module("org.eclipse.platform:org.eclipse.swt.gtk.linux.x86_64:3.114.0")
            }
            else if (os.contains("mac")) {
                substitute module('org.eclipse.platform:org.eclipse.swt.${osgi.platform}') with module("org.eclipse.platform:org.eclipse.swt.cocoa.macosx.x86_64:3.114.0")
            }
        }
    }
}
