Gradle を使った IntelliJ プロジェクトで "Cannot resolve symbol" を解消する

More than 1 year has passed since last update.

Java 力が皆無なので、日々しょうもないことを学んでいる。

今日の「しょうもない学び」は build.gradle に次の記述をしたのに、IntelliJ で import lombok.Data; が "Cannot resolve symbol" と言われてしまったのを解消した件だ。

dependencies {
    compile 'org.projectlombok:lombok:1.16.10'
}

本当にしょうもない話だけど、"File" => "Invalidate Caches / Restart..." を選択して IntelliJ を再起動すると、キャッシュが削除された状態で IntelliJ が再起動される。さらに、わたしのケースでは "Import Module from Gradle" というウィンドウが立ち上がり、そこで "Use gradle wrapper task configuration" にチェックを入れることで問題を解消できた (gradlew ファイルが作成される)。

しょうもな過ぎて Qiita に書くのもためらわれるけど、しょうもないレベルなのを受け入れてやっていくしかない...。
