错误消息“Android Gradle插件需要Java11才能运行。您当前使用的是Java1.8”

Question

我下载了最新的Android Studio，我想运行Android Jetpack Compose项目，但当我运行它时，我得到了错误：

> Failed to apply plugin 'com.android.internal.application'.
> Android Gradle plugin requires Java 11 to run. You are currently using Java 1.8.
You can try some of the following options:
- changing the IDE settings.
- changing the JAVA_HOME environment variable.
- changing `org.gradle.java.home` in `gradle.properties`.

我已经下载了Java11，并在gradle.properties中添加了Java11。

org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk-11.0.10.jdk/Contents/Home

JAVA_HOME显示Java11，但当我运行时，它不起作用-/library/Java/javavirtualmachines/jdk-11.0.10.jdk/contents/home

确保您的Gradle使用的是正确的JDK。尝试在项目目录中运行./gradlew--version。输出应该如下所示：

Gradle 7.0-rc-2
------------------------------------------------------------

Build time:   2021-04-01 21:26:39 UTC
Revision:     912a3368b654b71250dfc925a20d620393

Kotlin:       1.4.31
Groovy:       3.0.7
Ant:          Apache Ant(TM) version 1.10.9 compiled on September 27 2020
JVM:          11.0.10 (Ubuntu 11.0.10+9-Ubuntu-0ubuntu1.20.10)
OS:           Linux 5.11.4-051104-generic amd64

如果JVM指向版本1.8，那么您应该在设置中更改它。您可以在首选项→构建、执行、部署→构建工具→分级→*分级JDK中找到它。
