爪哇/gradlew desktop:运行不起作用，但设置配置起作用：libgdx

Question

当我在Android Studio终端中运行./gradlew desktop:run时，它无法运行。但当我设置一个运行配置（Gradle任务，Gradle项目是我的项目，运行任务是“desktop:run”）时，它工作得非常好。（另外./gradlew 安卓:run也不起作用，它只在我运行自动创建的安卓配置时起作用。）

./gradlew desktop:run：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '10.0.2'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

./gradlew 安卓:run：

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '10.0.2'.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

编辑：网络上的一些页面建议我使用旧的java版本，但这不起作用

您可能正在Gradle包装器中使用的Gradle版本太旧，无法识别JDK 10。当您直接在Android Studio中运行时，它可能会使用自己的Gradle版本（我认为在导入项目时有一个设置，决定Android Studio是否会使用包装好的Gradle）

因此，您可以降级JDK或升级Gradle包装器版本。降级JDK是一件痛苦的事，因为他们已经开始从Sun下载网站上删除旧版本。而且你可能有一些非LibGDX的东西想要用一个新的JDK来处理

要升级Gradle包装，请打开/gradle/wrapper/gradle-wrapper.properties，并将末尾的文件名更改为gradle-5.1.1-bin.zip。至少，这是我所使用的，它适用于JDK 12

然后，您需要将build.gradle文件中的compile关键字替换为implementation。在/desktop/build.gradle中，将from files(sourceSets.main.output.classesDir)行更改为from files(sourceSets.main.output.classesDirs)（在末尾添加一个s）
