错误消息“Android Gradle 插件需要 Java 11 才能运行.您当前使用的是 Java 1.8"

问题描述

我下载了最新的 Android Studio，我想运行 Android Jetpack Compose 项目，但是当我运行它时，出现错误:

I downloaded the newest Android Studio, and I wanted to run the Android Jetpack Compose Project, but when I ran it, I got the error:

> 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 Java 11 并在 gradle.properties 中添加了 Java 11.

I already downloaded Java 11 and added Java 11 in gradle.properties.

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

JAVA_HOME 显示 Java 11，但是当我运行时，它不起作用 -/Library/Java/JavaVirtualMachines/jdk-11.0.10.jdk/Contents/Home

The JAVA_HOME shows Java 11, but when I run, it doesn't work -/Library/Java/JavaVirtualMachines/jdk-11.0.10.jdk/Contents/Home

我该怎么办?

推荐答案

确保您的 Gradle 使用正确的 JDK.尝试在项目目录中运行 ./gradlew --version.输出应该是这样的:

Make sure that your Gradle is using the proper JDK.Try running ./gradlew --version in your project's directory. The output should be something like this:

Gradle 7.0-rc-2

Kotlin:       1.4.31
Groovy:       3.0.7
Ant:          Apache Ant(TM) version 1.10.9 compiled on September 27 2020

OS:           Linux 5.11.4-051104-generic amd64

如果 JVM 指向 1.8 版，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 → Gradle → *Gradle JDK 中找到它.

If the JVM points to version 1.8 then you should change it in settings. You can find it in Preferences → Build, Execution, Deployment → Build Tools → Gradle → *Gradle JDK.
