spirngboot 3.3.1 + JDK17;

Problem occurred during migration from Springboot 2.7 to 3.3

To migrate to Springboot 3.0, I have newly written from gadle.build to gardle.build.kts

Because the existing entity code is Java code, we used annotationProcessor instead of KPAT plugin.

//queryDSL
implementation("com.querydsl:querydsl-jpa:5.0.0")
annotationProcessor("com.querydsl:querydsl-apt:5.0.0")
annotationProcessor("jakarta.annotation:jakarta.annotation-api")
annotationProcessor("jakarta.persistence:jakarta.persistence-api")

I expecting generated QClass
