ノウハウ
Java Platform Support
- VSCode拡張機能からインストール
- インストールすると、JDKがインストール済みかチェック
インストールしていないので、エラーメッセージが出る
- OKをクリックした後、右下にJDKのダウンロードを促す通知が出る！
- 「Downloade JDK and setup automatically」をクリックすると、「JDK Downloader」画面が表示される
- 「Download Oracle OpenJDK」を選択すると、バージョン等が表示される
問題なければ、「Install and start setup」をクリック
- インストール結果が右下に通知され、完了したので、「Reload now」をクリックして、再読み込みを行う
