grails - Grails 3 schemaExport には、sitemesh.xml を検索する FileNotFoundException の警告が含まれています

Question

Grails 3.3 アプリケーションに対して Gradle を使用してschemaExportを実行すると、 ddl.sqlが作成されますが、以下の警告がログに記録されます。Grails 3 のドキュメントによると、sitemesh.xml は削除されているため、当然ファイルは使用できません。何か不足していますか？

ツールとバージョン: Grails 3.3.0、Gradle 3.3、Hibnerate 5、Sybase ASE 15.7
