Swag init generates nothing but "general API information"

问题

问题描述
在使用swag init命令时，当使用多个目录和--parseDependency和--parseInternal标志时，Swaggo无法递归解析Go文件中的Swagger注释。只有使用-g标志指定的主文件中的注释被解析，而指定目录中其他文件中的注释不被考虑。

包含Swaggo注释的文件是internal/transport/http/v1/auth.go、internal/transport/http/v1/trip.go和cmd/app/main.go。

仓库结构在这里。

我运行的命令：
swag init -d cmd/app/ -g main.go --parseDependency --parseInternal

swag init -d cmd/app/,internal/transport/http/v1 -g main.go --parseDependency --parseInternal

上述所有命令产生相同的结果。

结果

Issue Description
Swaggo fails to recursively parse Swagger comments in Go files when using the swag init command with multiple directories and the --parseDependency and --parseInternal flags. Only the comments in the main file specified with the -g flag are parsed, while the comments in other files within the specified directories are not considered.

Files that contain swaggo comments are internal/transport/http/v1/auth.go, internal/transport/http/v1/trip.go, and cmd/app/main.go

Repo structure is here

commands I have run:
swag init -d cmd[enter image description here][1]/app/ -g main.go --parseDependency --parseInternal

swag init -d cmd/app/,internal/transport/http/v1 -g main.go --parseDependency --parseInternal

All the commands above produces the same result

答案1

得分: 1

在使用v1.8.16时，我也遇到了同样的问题。降级到v1.8.4后，一切正常。你可以尝试降级，这样在swaggo中就能正常工作了。

Have the same issue too when using v1.8.16. Everything works fine after downgrading to v1.8.4. You should try downgrade and it work in swaggo
