STS（SpringSource Tool Suite）の単純なSpringバッチプロジェクトテンプレートを使用して、サンプルのSpringバッチプロジェクトを実行しようとしています。

これを行うために、Eclipseで次の手順を実行しました。

右クリック->新規->その他の選択したSpringSourceツールスイート->SpringTemplate Project-> SimpleSpringBatch関連するプロジェクト名とパッケージ名を入力しました

次に、を使用してプロジェクトを実行しようとします

mvn exec:java

次のエラーが発生します。

HSQLDBドライバーが見つからないか、正しくロードされていないようです。

Mavenの依存関係を確認しましたが、hsqldbは間違いなくそこにあり、クラスパスでEclipseにプルインされています。

    <dependency>
        <groupId>hsqldb</groupId>
        <artifactId>hsqldb</artifactId>
        <version>1.8.0.7</version>
    </dependency>

なぜ私がこれを見るのか、何か考えはありますか？

編集：ApplicationContextxmlを追加しました

<?xml version="1.0" encoding="UTF-8"?>

ときどき、Eclipse の動作がおかしくなることがあります。Eclipse は、新しく追加された依存関係 (HSQLDB ドライバー) でプロジェクトのビルド パスを更新できないと思います。eclipse http://www.eclipse.org/m2e/用の Maven 統合プラグインを使用することをお勧めします。これにより、Eclipse(juno) マーケットプレイスからダウンロードできます。
