EclipseでJDKのバージョンが合っているのにエラーが出たりコンパイラが正常に動作しない場合

Last updated at Posted at 2017-11-22

EclipseでJDKのバーションが合っているのにエラーが出たりコンパイラが正常に動作しない場合の対処方法

手順

  1. Window->Preferences->Java->Compilerを開く
  2. JDK ComplianceのCompiler compliance levelを一旦、他のバージョンに変更
  3. Apply and Closeを押す
  4. 確認画面が出るのでYesを押し、処理が終わるまで少し待つ
  5. 1の画面からCompiler compliance levelを目的のバージョンに戻す
  6. 3,4の手順を行う

表示上では設定は間違えてないのにJDKが正常に動作していない時などは、この操作で治るかもしれないです。
