swag init can't generate api info in swagger.json

[gjxgjxgjxgjx]

when i run 'swag init', no api info has been generated in swagger.json

swag.exe version v1.16.3 go version go1.22.1 windows/amd64 i use the examples provided on the official website and filled in the correct package name.

package main

import (
    "net/http"

    docs "oj/docs"

    "github.com/gin-gonic/gin"
    swaggerfiles "github.com/swaggo/files"
    ginSwagger "github.com/swaggo/gin-swagger"
)

// @BasePath /api/v1

// PingExample godoc
// @Summary ping example
// @Schemes
// @Description do ping
// @Tags example
// @Accept json
// @Produce json
// @Success 200 {string} Helloworld
// @Router /example/helloworld [get]
func Helloworld(g *gin.Context) {
    g.JSON(http.StatusOK, "helloworld")
}

func main() {
    r := gin.Default()
    docs.SwaggerInfo.BasePath = "/api/v1"
    v1 := r.Group("/api/v1")
    {
        eg := v1.Group("/example")
        {
            eg.GET("/helloworld", Helloworld)
        }
    }
    r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerfiles.Handler))
    r.Run(":8080")

}

I am also in the same situation, and it can detect annotation information on the main function, but it cannot scan API information with added annotations. Have you resolved it now?
