gradle - 使用 Kotlin Sync 配置 Clean LibGDX 项目失败，类型代码无效 :82

Question

我正在尝试使用 kotlin 配置干净的 libgdx 项目。首先我使用 libgdxs 工具生成了一个干净的项目，然后即使我在官方文档中做了所有事情，我也同步失败
原因:无效类型代码:82

我做了这里写的一切:

主项目目录 build.gradle:

请尝试添加
源兼容性 = 1.8
目标兼容性 = 1.8
在您的 build.gradle 中检查一次

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


            dependencies {
                sourceCompatibility = 1.8
                targetCompatibility = 1.8

                compile "com.badlogicgames.gdx:gdx:$gdxVersion"
                compile "com.badlogicgames.gdx:gdx-box2d:$gdxVersion"
                compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlinVersion"
                compile "org.jetbrains.kotlin:kotlin-reflect:$kotlinVersion"



            }
}
