Android Studioで初めてのビルドがうまくいかない時にしたこと。(Mac)

Posted at

Flutter大学のこの動画を観ながら環境構築していましたが、Android Studioの最初のビルドがうまくいかず、困っていましたが、解決できたので、記事にしておきます。

前提

  • MacOS Big Sur バージョン 11.5
  • Android Studio 2020.3.1.22

出てきたエラーメッセージ

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> Kotlin could not find the required JDK tools in the Java installation '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home' used by Gradle. Make sure Gradle is running on a JDK, not JRE.

* 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.

* Get more help at https://help.gradle.org

BUILD FAILED in 1s
Exception: Gradle task assembleDebug failed with exit code 1

どうやら、JDKにパスが通っていないということらしいので、こちらの記事にしたがって、JDKをインストールしたらうまくいきました。

[1] https://adoptopenjdk.net にアクセス

[2] [OpenJDK 11]・[HotSpot]を選択したあと、[Latest Release]をクリック

[3] インストール

[4] ターミナルで下記コマンドを実行

cd ~
echo JAVA_HOME=/Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk/Contents/Home >> .zshrc
