POI(poi-3.7とpoi-ooxml-3.7を含む)を使用してGrailsプロジェクトを構築しました。プロジェクトのBuildConfig.groovyファイルの依存関係ブロックにこれら2つの外部ライブラリを追加しました。私がそれをコンパイルしたとき、何も奇妙なことはありません。しかし、そのプロジェクトに対してコマンド「run-app」を呼び出すと、以下のスタックトレースでエラーが発生しました。

そして、これが私の構成です:
dependencies {
provided ('com.oracle:ojdbc6_g:11.2.0.1.0')
runtime ('org.apache.poi:poi:3.7', 'org.apache.poi:poi-ooxml:3.7')
}
これを解決するにはどうすればよいですか?どうもありがとう!
