Kotlin 如何设置/构建LibGDX+；科特林项目正确吗？

我已经下载了gdx-setup.jar，并尝试使用以下设置构建空项目：

下面是我在控制台中得到的信息：

如果我没有标记“Use Kotlin”，它构建得很好，那么这是为什么？我做错了什么？

好吧，我终于找到了如何使用Kotlin正确构建项目的方法（如果你在gradle上遇到问题，它也会帮助你）。首先，您只需在不使用“Use Kotlin”的情况下构建它，然后像这样编辑project build.gradle文件：

buildscript {
    ext.kotlinVersion = '1.1.1'

    repositories {
        mavenLocal()
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"

    }
}

如果jcenter（）之后有

google（）

，也应该删除它

在

中：桌面
用
kotlin
插件替换
java
，并添加
kotlin stdlib

project(":desktop") {
    apply plugin: "kotlin"

    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-lwjgl:$gdxVersion"
        compile "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-desktop"
        compile "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-desktop"
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
    }
}

project(":android") {
    apply plugin: "android"
    apply plugin: "kotlin-android"

    configurations { natives }

    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi-v7a"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-arm64-v8a"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86_64"
        compile "com.badlogicgames.ashley:ashley:$ashleyVersion"
        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi-v7a"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-arm64-v8a"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86_64"
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"

    }
}

project(":core") {
    apply plugin: "kotlin"

    dependencies {
        compile "com.badlogicgames.gdx:gdx:$gdxVersion"
        compile "com.badlogicgames.ashley:ashley:$ashleyVersion"
        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
    }

在

插件和
kotlin-stdlib

project(":desktop") {

        compile "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-desktop"
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
    }
}

project(":android") {
    apply plugin: "android"
    apply plugin: "kotlin-android"

    configurations { natives }

    dependencies {
        compile project(":core")
        compile "com.badlogicgames.gdx:gdx-backend-android:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-armeabi"

        natives "com.badlogicgames.gdx:gdx-platform:$gdxVersion:natives-x86_64"
        compile "com.badlogicgames.ashley:ashley:$ashleyVersion"
        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-armeabi"

        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86"
        natives "com.badlogicgames.gdx:gdx-freetype-platform:$gdxVersion:natives-x86_64"
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"

    }
}

project(":core") {
    apply plugin: "kotlin"

    dependencies {

        compile "com.badlogicgames.gdx:gdx-freetype:$gdxVersion"
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
    }

    }
}

如果你有kotlin的问题，那就足够了

如果您也像我一样有gradle问题，请打开
gradle wrapper.properties
并将gradle版本修复为3.3：

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-bin.zip

尝试在不使用“UseKotlin”的情况下构建，然后直接导入它，就像在这里一样。你运气好吗？我似乎也有类似的问题。请注意，Kotlin 1.3与gradle 2.2（默认的libgdx-gradle版本）并不匹配。如果存在构建问题，请升级gradle。
