在Gradle中使用SWT的java无法解析所有依赖项

Question

我试图在Gradle项目中使用最新的Eclipse SWT 3.114.0，但我得到了以下结果：

   > 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'
}

我错过了什么

Answer 1

首先，SWT现在正在Maven Central上正式发布，所以您可能应该将mavenCentral()添加到您的repositories块中

其次，maven属性osgi.platform似乎不是由gradle处理的。相反，您必须进行一些特殊的依赖项解析，以正确获取特定于平台的依赖项

以下内容应该很好（摘自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")
            }
        }
    }
}
