Unreal Header Tool Plugin Regarding cpp file output

Development Pipeline & Plugins

I am making a plugin for UnrealHeaderTool.
I would like to know the proper way on how to output the cpp file.

↓Link to the project of the plugin you are creating

I am still implementing it with reference to the UHT built-in exporter “UhtCodeGenerator” and making sure that the output cpp file is built.
However, I am experiencing a bug where the generated cpp files are constantly regenerated under the influence of the ““UhtCodeGenerator”” code.

We have investigated and found the following

  1. only “.gen.cpp” files are build targets
    It seems that the cpp file generated in the “UEBuildModuleCPP” section is the target of compilation.
    Looking at the code, I see that the extension cannot be specified here and must be “gen.cpp”.

  2. extra files are deleted at “UhtSession.CullOutputDirectory”.
    The file format of each exporter’s output file format is used to delete unnecessary files. (This is for automatic deletion when the h file on the project side is deleted.
    Deletion is performed according to the naming convention of CppFilters and HeaderFilters of each exporter.
    Since “*.gen.cpp” is included in the CppFilters written in “UhtCodeGenerator”, the code of the home-made plugin seems to be deleted during the session of UhtCodeGenerator.
