如何将 Android 项目升级到 Java 11 [英] How to upgrade an Android project to Java 11

问题描述

我正在使用最新的 Android Studio Arctic Fox 2020.03.01 Canary 8 和 AGP 7，并且我想将我的项目转换为使用 Java 11.显然，仅执行以下操作并不能像

之前

我假设您安装了 Java 11 或更高版本.以下步骤:

文件 ->项目结构 ->SDK 位置 ->将 JDK 位置更改为 Java 11 jdk 文件夹

如果您使用的是 Mac OS，请尝试在以下位置搜索该文件夹:

/Library/Java/JavaVirtualMachines/jdk-11.0.9.jdk/Contents/Home

I am using the latest Android Studio Arctic Fox 2020.03.01 Canary 8 and AGP 7, and I want to convert my project to use Java 11. Apparently just doing the following does not work as mentioned on https://developer.android.com/studio/preview/features#use-java-11:

android {
    compileSdkVersion 30

    compileOptions {
      sourceCompatibility JavaVersion.VERSION_11
      targetCompatibility JavaVersion.VERSION_11
    }

    // For Kotlin projects
    kotlinOptions {
      jvmTarget = "11"
    }
}

I get the following error when I build:

Execution failed for task ':app:compileDebugJavaWithJavac'.
> Could not resolve all files for configuration ':app:androidJdkImage'.
   > Failed to transform core-for-system-modules.jar to match attributes {artifactType=_internal_android_jdk_image, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}.
      > Execution failed for JdkImageTransform: /Users/azfarsiddiqui/Library/Android/sdk/platforms/android-30/core-for-system-modules.jar.
         > jlink executable /Applications/Android Studio Preview.app/Contents/jre/jdk/Contents/Home/bin/jlink does not exist.

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

To keep it simple, I've been trying this on a Jetpack Compose sample project here: https://github.com/android/compose-samples/tree/main/JetNews

Any thoughts? Thanks guys

解决方案

Android Studio Artic Fox 2020.3.1

Preferences (Settings) -> Build, Execution, Deployment -> Build Tools -> Gradle -> Gradle JDK -> Select JDK 11 or download JDK

Before

I assume you have Java 11 or later installed. Following steps:

File -> Project Structure -> SDK Location -> Change JDK Location to the Java 11 jdk folder

If you are using Mac OS then try to search for that folder in:

/Library/Java/JavaVirtualMachines/jdk-11.0.9.jdk/Contents/Home
