无法应用插件：找到 java 版本 11 最低要求是 1.8。尚不支持 11.0.0 及更新版本
Failed to apply plugin: Found java version 11 Minimum required is 1.8. Versions 11.0.0 and newer are not supported yet
我正在尝试在 MacOS 10.14.6 上使用 IntelliJ 2017.3.4 构建 Minecraft Forge MDK。当我执行 gradlew build 时，出现以下错误：
Failed to apply plugin [id 'net.minecraftforge.gradle']
Found java version 11.0.4. Minimum required is 1.8.0_101. Versions 11.0.0 and newer are not supported yet.`
但是，我什至没有安装 Java 11。项目结构设置为1.8:
我也将 IDE 引导 jdk 切换为 1.8:
并且在其他设置 --> 默认项目结构中我也将其设置为 Java 8:
尽管如此，gradle 认为我正在尝试使用 Java 11。我究竟如何让它识别出我正在使用 Java 8？

你说：
However, I don't even have Java 11 installed.
错误消息说："Found java version 11.0.4."
这意味着您确实安装了 Java 11。您可能没有自己安装它，或者您可能尝试过卸载它。但它肯定在那里。 Gradle 已找到 Java 11 安装，其 java 命令报告其版本号为 11.0.4。
查看 gradlew 脚本，它使用两种方法来决定使用哪个 Java 安装：
如果设置了 JAVA_HOME 环境变量，脚本会在变量指向的安装中查找 java 可执行文件。
如果没有设置JAVA_HOME环境变量，则在命令搜索路径上使用java命令；即根据 PATH 环境变量指定的内容。
所以，检查这两个环境变量说的是什么......在 shell 你所在的地方 运行 gradle 命令。我建议设置 JAVA_HOME。它需要指向您的 Java 8 安装目录。
（您可以将正确的 JAVA_HOME 设置从路径反向工程到您的 Java 8 java 命令以及 gradlew 脚本正在执行的操作。）
请注意 Java 的多个安装将在 Mac 上愉快地共存。您只需要确保您的 PATH and/or JAVA_HOME 变量指向正确的位置......对于您当前正在使用/想要使用的版本。
