依存関係以下はJunit4（PowerMock）にモック

を実装しながら、私のJUnitテストケースである：依存関係以下はJunit4（PowerMock）にモック

     } 
     catch (Exception e) 
     {

私はビルド・パス

powermock-easymock-1.4.10-フルに次のJARが含まれています。ジャー
powermockモジュール-junit4-1.6.6.jar
easymock-3.4.jar
powermockコア-1.6.6.jar

はまだ依存関係に次のエラーを取得：

はなぜJUnitの4はあまり依存関係を必要としてからかっていますか？私はちょうど2つまたは3つの瓶でそれを行うことはできませんか？別のエラーを取得してビルド・パスにCGLIBを追加した後

あなたはcglibライブラリが欠落しています。

thisを参照してください。 cglibがPowerMockからどのように進化して、独自のライブラリになるかを説明しています。

すべてを一括して取得する最も簡単な方法は、downloadsのドキュメントを読んで従ってください。そこにはさまざまなZIPファイルがあります。

PowerMock + easymock + JUnitを使用する場合は、そこからpowermock-easymock-junit-1.7.0.zipをダウンロードしてください。 ZIPファイルを解凍し、すべて JARをクラスパスに含めます。

これを参照してください。今、私はcglibを追加しましたが、もう一つのエラーが発生しました。質問自体にエラーが追加されています – ShraddhaJ

トレースのcglibの期待バージョンはどこですか？ – ShraddhaJ

ありがとうございました。助けてくれてありがとう。 – ShraddhaJ
