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?

当前回答

这里的所有解决方案对Java 11都有帮助。但是如果你不想升级到Java 11,那么你应该把Android Gradle插件(ADP)降级到4。X如下图所示:

其他回答

如果你不想使用JDK 11,仍然想使用JDK 1.8,你可以恢复Android插件,如下所示。

plugins {
    id 'com.android.application' version '4.2.0' apply false
    id 'com.android.library' version '4.2.0' apply false
}

我是如何解决这个问题的…

如果在Gradle属性和环境变量中设置Java版本似乎没有任何效果,有可能是Gradle中的全局设置阻止了你的设置。

C:\Users\<yourUserName>\.gradle

寻找一个名为gradle.properties的文件。如果

org.gradle.java.home

,则其值将覆盖您在项目中使用的任何设置。

因此,解决方案是删除这一行,或者在那里设置你想要的java版本。在我的情况下,我得到了它的工作是编辑文件,看起来像

#org.gradle.jvmargs=-Xmx1536M
android.enableR8=true
android.useAndroidX=true
android.enableJetifier=true

org.gradle.java.home=C:\\Program Files\\Microsoft\\jdk-11.0.12.7-hotspot

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.

你可以用这种简单的方法来解。

访问https://www.oracle.com/java/technologies/javase-jdk16-downloads.html 下载系统的JDK ZIP文件。(比如说Windows) 将其解压到PC主目录下具有高权限的任何文件夹中 现在打开并转到位于men File*→project structure的Android studio项目结构。 然后将解压JDK版本的目录粘贴到这里。正如你所看到的,我的是JDK 16,并安装在这个目录中,如图所示:

你可以这样做(菜单文件→构建选项):
