启动Jetty服务器时扫描条目“module-info.class”时出错
我最近在启动java服务器时看到了这个。 有没有人见过这个？ 如果是这样的话怎么办？ 我可以确认jar和module-info.class存在于相关路径中。

Jetty 9.4.9（或更新版本）支持从Java 9更改新的JAR文件。
有关Java 9function的问题：
- https://github.com/eclipse/jetty.project/issues/1692 – 从字节码扫描中排除
module-info.class。 - https://github.com/eclipse/jetty.project/issues/1797 – 正确支持
META-INF/versions/*多版本JAR文件（JEP 238）。
