minimizeJar = trueでシェードを使用するとNullPointerExceptionが発生する

シェードとminimizeJarを使用すると、シェードプラグインからNullpointerExceptionが発生します。minimizeJar = trueでシェードを使用するとNullPointerExceptionが発生する

以下の例では、2つの依存関係を定義しています。 junitとcommons-lang3であり、私のコードではcommons-lang3 - StringUtilsの単一のクラスしか使用していません。シェードのドキュメントから私の理解は、使用されていないクラスは影付きのjarファイルには含まれないので、影付きのjarファイルにはクラスとStringUtilsのみが含まれると考えられます。

mvn clean packageを実行している私は、次の出力（この質問の最後に-X MVNきれいなパッケージのフル出力）を取得：

[ERROR]はゴールorg.apache.maven.pluginsの実行に失敗しました：mavenのシェード - プラグイン：2.4.3：日陰プロジェクトシェード上（デフォルト）：エラー日陰のjarファイルを作成：ヌル：NullPointerExceptionが - 次のバージョンで実行している場合> [ヘルプ1]

これは、次のとおりです。
