Jacocoは自分のWebサービスをテストしようとしたとき

Jacocoは（私はテスト段階を含む任意のMavenの目標とそれを得る）私は、このエラーを与えているのStringUtilsについての奇妙なエラーで私のシステムでのみ失敗します。

だけ明らかに、私はコード内でどこでもStringUtilsを使用しているわけではなく、テストコードでも使用していません。テストをスキップすると、私のプロジェクトはビルドされ、正常に動作します。

私はグーグルの問題、ジャココの問題、確かな問題を抱えて、私が出会ったすべてのソリューションを試してみました。 、クリーンビルド

• も
• 手動で全体のターゲットディレクトリを削除する元コモンズ-のlang-2.6.jarを含むPOMへのStringUtilsを含むいくつかの異なる依存関係を（追加と：ここ

  は、私が試したものです新しいコモンズ・lang3ライブラリ）

• 引き起こす可能性があるすべての可能な違いを見つけるために、同様のテストケースを使用して、私の他のプロジェクトと比較すると、すべてのリポジトリのライブラリ
• を再ダウンロードするために私の.m2 /リポジトリ/組織/ apacheの/ Mavenのディレクトリを削除しますポンポンで確実なフェールセーフの両方のプラグイン構成に<skipTests>true</skipTests>を追加する別の確実な、フェイルセーフのバージョン、および確実な-レポートプラグイン
• （テストケースを二回実行されていたので、私は読んでいくつかの同様の問題が起こった）
• を使用して、この
• Mavenのコンパイラプラグインの設定不足しているクラス名Aに一致する適切なディレクトリにjacocoポンポンに直接StringUtils.classを挿入
• で、ソースとターゲットのJDKのバージョンを変更jacocoプラグインの設定
• で<exclude>タグを使用して、さまざまな出力ディレクトリを除外ND Coberturaのへの切り替え
• （3.1.1と3.3.9の両方を試してみました）のMavenの異なるバージョンをインストールして使用してjacocoプラグイン
• の異なるバージョンを使用して
• をパッケージ（私は違い非常に類似したエラーが出ますStringUtilsではなくorg/apache/commons/lang/SystemUtils）

私はこれを1日中引き出しています。私は他の誰かにそれをテストさせることができました。ターゲットディレクトリを自分のマシンにコピーし、成功したビルド結果（jacoco.execとチェックインされたコード）に対してソナーコード分析を実行することができました。

私の質問は、私のシステムでこれが原因で何がうまくいかないのですか？

HP EliteDeskでWindows 7 64ビットを実行しています。ここに私のpom.xmlです：

私のテストケースは、何も特別なことではありません、彼らは基本的には、エンドポイントのそれぞれにサンプルPOSTリクエストを送信し、結果が戻ってくることを確認してください。ここで

は、例えば、テストケースである：

private CustomResponse executePostRequest() 
{ 
    MyPojo data = new MyPojo(); 
    data.setId(0); 
    data.setRequestType("sometype"); 
    data.setSomeField("value"); 
    data.setSomeOtherField(5); 
    return target.path(endpoint).request().post(Entity.json(data), CustomResponse.class); 
} 

@Test 
public void testEndpoint() 
{ 
    CustomResponse response = executePostRequest(); 
    assertTrue(response.getCode() == 200); 
} 

私は他の設定を投稿するか、あなたが私のシステムについて知りたいかもしれないものは何でもご満足いただけることでしょう。

更新：ちょうど約jHadesが見つかりました。このようなjar-hellシナリオに遭遇したときに競合するJarリソースを識別するのに役立つツールです。私はまだ試していないが、もし何かを生み出すならば、ここに結果を更新していく予定だ。
