Quarkus で Unable to locate appropriate constructor on class エラーが出た時

Quarkus の Hibernate Reactive with Panache を使っている時に上記エラーに遭遇したので対処方法をメモします。

ドキュメントにある Query projection を試そうとした時に、以下のエラーが出ました。

org.hibernate.hql.internal.ast.QuerySyntaxException: Unable to locate appropriate constructor on class [myClass]. Expected arguments are: long, java.time.LocalDateTime, java.time.LocalDateTime, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.time.LocalDateTime, java.lang.String, long, java.lang.String, int, java.lang.String, java.lang.String, long [SELECT new myClass (postAuthor, postDate, postDateGmt, postTitle, postExcerpt, postStatus, commentStatus, pingStatus, postPassword, postName, toPing, pinged, postModifiedGmt, postContentFiltered, postParent, guid, menuOrder, postType, postMimeType, commentCount) FROM myDtoClass WHERE postType = ?1 ORDER BY postModified DESC]

./mvnw quarkus:dev を実行しながら動作確認をすると発生します。 @RegisterForReflection はビルド時に登録されるようなので、 Quakus をビルドし直さないとうまく反映されないようです。

一旦 quarkus:dev を停止して再実行すれば動くようになります。止めるのが面倒な場合は、 quarkus:dev 実行中に pom.xml を更新(中身は変えずに保存してファイルの更新日時を変更)すれば自動で再コンパイルが走ります。

Quarkus のバージョン: 1.13.6
