呼吸找不到C＃接口

Question

我正在尝试使用doxygen，呼吸和狮身人面像来生成C＃库的文档。这是在Windows下。基本目录结构为：

docs
    index.rst
    conf.py
    xml
        xml output from doxygen

执行make.bat html时遇到以下错误：

  

C：\ Programming \ J4JLogging \ J4JLogging \ docs \ index.rst：25：警告：doxygeninterface：在目录“ ./xml”中的项目“ J4JLogger”的doxygen xml输出中找不到类“ IJ4JLoggerConfiguration”

这是conf.py的内容

# import os
# import sys
# sys.path.insert(0, os.path.abspath('.'))

project = 'J4JLogger'
copyright = '2019, Mark Olbert'
author = 'Mark Olbert'

extensions = [ "breathe" ]

breathe_projects = {
    "J4JLogger": "./xml"
}

breathe_default_project = "J4JLogger"

templates_path = ['_templates']
exclude_patterns = ['_build', 'Thumbs.db', '.DS_Store']
html_theme = 'sphinx_rtd_theme'
html_static_path = ['_static']

这是index.rst的内容：

You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.

Welcome to J4JLogger's documentation!
