我下载了最新的Android Studio,我想运行Android Jetpack Compose Project,但当我运行它时,我得到了一个错误:

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

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

JAVA_HOME显示Java 11,但当我运行时,它不工作 /图书馆/ Java / Home / JavaVirtualMachines / jdk-11.0.10.jdk /内容

我该怎么办?

我的Android Studio版本

我再次下载了11 JDK,它可以工作了。这节省了您的时间,因为您不必清除缓存,构建和重新构建项目。

其他回答

如果你目前正在使用Android Studio Arctic Fox (4.2):

您可以手动设置Gradle JDK(菜单Preferences→Build Tools→Gradle→Gradle JDK(使用或下载JDK 11)) 在所有项目中恢复默认设置,不要执行前面的技巧(菜单文件→管理IDE设置→恢复默认设置)

确保你的Gradle使用了正确的JDK。 试着在项目目录下运行。/gradlew——version。输出应该是这样的:

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

当我在北极狐构建的终端中开始gradlew ktlintFormat时,我得到了这个错误。

I opened Project Structure (menu File → Project Structure) and selected Java 11, but it didn't help even after a restart of Android Studio. Then I changed the Java path in Settings (see the accepted answer), but it didn't help. You should set it. I tried to change Windows system variables and changed JAVA_HOME. (A short way: run cmd with administrative rights and write: setx /M JAVA_HOME "C:\Program Files\Java\jdk-11.0.11", and then restart Android Studio) Press Win+X, press "System", and enter "va". I pressed Edit button and "Browse Directory...", and then selected JRE (or JDK) folder (without bin) of Java 11. Then OK, and OK (as always). I opened cmd (command line in Windows) and typed: %JAVA_HOME%. It wrote me this error: 'C:\Program' is not recognized as an internal or external command, operable program or batch file. Looking at Setting the JAVA_HOME Variable in Windows, I found that we should replace Program Files with Progra~1 (yes, this DOS trick still works). So, replace JAVA_HOME again like in the picture below (C:\Progra~1\Android\Androi~1\jre). Restart Android Studio or reset the computer.

如果你正在使用MS App Center,当你在Android项目中使用Java 11时,你可能会面临同样的问题。如果您正在寻找MS应用程序中心问题的解决方案。这可能对你有帮助!

访问https://appcenter.ms/users/user1/apps/yourapp/build/branches 单击设置图标转到生成配置 向下滚动到环境并打开。 设置JAVA_HOME为$(JAVA_HOME_11_X64)
