I use with Gradle 8.5 and jdk 21.0.1 and spring boot 3.x,no problem. the error key word is "recreate". this is a annotations process error happen when dupplicated file name recreate. I guess your setting may have some problem.

@Gaga-for-coding you can try to remove the querydsl-apt dependencies from </dependencies> and leave it only inside the <plugin> as dependency. Also might be necessary to add the jakarta classifier there. This is what worked for me at least.
