编辑：由于我的问题似乎特定于我的设置，我在这里提供了一个完整的最小工作示例。
这是我的 Maven 设置 ( pom.xml)：

当使用 asciidoctor-pdf 转换为 PDF 时，我无法为 .adoc 文件设置字体大小（或样式）。根据文档，我可以指定它如下：
base:
font_size: 8
line_height_length: 10
所以我把它放在我的 .adoc 文件的顶部。但是生成的 PDF 并未反映此更改。您能否提供一个 .adoc 文件作为示例，该文件指定不同的字体大小或样式？坦吉斯
我使用asciidoctor-pdf将adoc文档转换为pdf，但总是出现“不是已知字体”的错误，在命令行后添加--trace时，错误是
