我正在使用与Jetty/Jersey的Swagger的2.1.16，我得到这个异常。我曾尝试在SwaggerConfiguration上使用readAllResources(false)关闭类路径扫描，因为我不想要这个功能，但它没有帮助。我可能做错了什么。但是什么?
谢谢,乔纳森。

Swagger包含一个过时版本的io.github.classgraph，导致java.lang.NoClassDefFoundError。我能够排除由Swagger包含的classgraph版本，并包含最新的版本。在那之后，我在module-info.java中丢失了require语句，现在它可以工作了。这个问题已经在master of Swagger repo中修复了，但还没有在任何版本中修复。
我在maven依赖中遇到了一个问题:
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.4</version>
</dependency>
唯一对我有用的是降级到1.6.3，它摆脱了Cannot resolve io.github.classgraph:classgraph:4.8.138的错误。
