私はJavaでプロジェクトを実行しました。つまり、javaCVライブラリを使用したモーション検出ソフトウェアです。NetBeansからコードをデバッグすると、正しく機能します。動きを検出してアラームを鳴らしたり、メールを送信したりします。しかし、コードをクリーンアップしてビルドすると、取得した.jarファイルがWebカメラをロードしていません。その.jarファイルを開くと、空白のキャンバスが表示されます。私が提供できるもう1つの情報は、クリーンアップしてbulidを実行すると、o/pに非推奨のAPIなどの警告が表示されることです。

出力は、コマンドラインから実行する必要があることを示していますjava -jar "C:\Users\Anooj\Documents\NetBeansProjects\projectlogin\dist\projectlogin.jar

distディレクトリから実行すると、プロジェクトに必要なライブラリが含まれます。関連付けられたライブラリなしでプロジェクトを実行しようとしていると思われます。
