即使 java gradle 工具链设置为 jdk 11，Gradle 仍使用 Java 1.8 构建 android 项目

FAILURE: Build failed with an exception.

A problem occurred evaluating project ':app'.
> 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`.

Gradle 检测本地安装的 JVM Gradle 选择符合构建要求的 JRE/JDK（在本例中为支持 Java 14 的 JVM） 如果没有找到匹配的JVM，会自动从AdoptOpenJDK下载匹配的JDK

Android Gradle 插件支持新的 gradle 工具链吗？https://docs.gradle.org/current/userguide/toolchains.html https://docs.gradle.org/current/userguide/toolchains.html

著名的库/插件/版本

• 运行 AGP 7.0.0-alpha03
• 科特林 1.4.21
• Android Studio 北极狐金丝雀 3
• jvm目标 1.8
• gradle 包装器 6.8-rc-1

下面的应用程序模块 gradle 配置（删除了一些细节）

android {

    java {
        toolchain {
            languageVersion = JavaLanguageVersion.of(11)
        }
    }

    kotlinOptions {
        jvmTarget = Versions.jdkNumber
        useIR = true
    }

    buildToolsVersion Config.buildToolsVersion
    compileSdkVersion Config.compileSdk

    buildFeatures {
        compose true
        dataBinding true
    }

    composeOptions {
        kotlinCompilerVersion Versions.kotlin_version
        kotlinCompilerExtensionVersion Versions.compose
    }

    androidExtensions {
        experimental = true
    }
}

你可以看看这个。我有一个类似的问题，它为我解决了。这是 Gradle 自己的代码“片段”，用于解决您所面临的问题。

import org.jetbrains.kotlin.gradle.dsl.KotlinJvmCompile

plugins {
    id "org.jetbrains.kotlin.jvm" version "1.4.20"
}

repositories {
    jcenter()
}

// tag::compiler-kotlin[]
def compiler = javaToolchains.compilerFor {
    languageVersion = JavaLanguageVersion.of(11)
}

tasks.withType(KotlinJvmCompile).configureEach {
    kotlinOptions.jdkHome = compiler.get().metadata.installationPath.asFile.absolutePath
}
// end::compiler-kotlin[]

这是在https://github.com/gradle/gradle/blob/master/subprojects/docs/src/snippets/java/toolchain-kotlin/groovy/build.gradle https://github.com/gradle/gradle/blob/master/subprojects/docs/src/snippets/java/toolchain-kotlin/groovy/build.gradle

我将它合并到我的项目中https://github.com/7ep/r3z/blob/51cc69bb6396c34f0507b67763487c9bc171a03e/build.gradle#L36 https://github.com/7ep/r3z/blob/51cc69bb6396c34f0507b67763487c9bc171a03e/build.gradle#L36

祝你好运！
