推荐答案

如果你不想为 Android 开发 Java 11 可以很好地使用 libgdx.

IF you do not want to develop for Android Java 11 works fine libgdx.

您必须在一切构建和运行之前更改一些内容.
这是我为使我的项目正常工作所做的工作.
我的上下文 Mac OSX 10.14 和 openJDK 11.0.2、新项目、桌面启动器和一堆扩展(不重要).

You have to change some things before everything builds and runs.
Here's what I did to get my project working.
My context Mac OSX 10.14 and openJDK 11.0.2, new project, Desktop launcher and a bunch of Extensions (not important).

1. 你得到的关于找不到 java 11.0.x 的错误来自 gradle.Java 11 仅从 gradle 5 开始支持.为了使用 gradle 5 而不是 4.6 生成的项目配置，请转到 /gradle/wrapper/gradle-wrapper.properties并将 distributionUrl=https://services.gradle.org/distributions/gradle-4.6-all.zip 更改为 distributionUrl=https://services.gradle.org/distributions/gradle-5.0-all.zip.

1. The error you get about not being able to find java 11.0.x comes from gradle. Java 11 is only supported since gradle 5. In order to use gradle 5 instead of 4.6 the generated project is configured with, go to <project-dir>/gradle/wrapper/gradle-wrapper.properties and change distributionUrl=https://services.gradle.org/distributions/gradle-4.6-all.zip into distributionUrl=https://services.gradle.org/distributions/gradle-5.0-all.zip.

这解决了 java 11 错误，只是为了让您遇到一个新错误Could not get unknown property 'classesDir' for main classes of type org.gradle.api.internal.tasks.DefaultSourceSetOutput.

That resolves the java 11 error just to confront you with a new error Could not get unknown property 'classesDir' for main classes of type org.gradle.api.internal.tasks.DefaultSourceSetOutput.

1. 要摆脱这种情况，请打开 <project-dir>/desktop/build.gradle 并更改第 27 行(您可能会有所不同)
   从文件(sourceSets.main.output.classesDir) 到
   来自文件(sourceSets.main.output.classesDirs)

1. To get rid of that, open <project-dir>/desktop/build.gradle and change line 27 (might be different for you)
   from files(sourceSets.main.output.classesDir) into
   from files(sourceSets.main.output.classesDirs)

就是 classesDir 变成 classesDirs

这应该可以解决所有构建错误，您可以开始了.

This should resolve all build errors and you're good to go.
