如何在JShell中提供javadoc文档？

我正在使用JShell来测试一个库，我通过类路径为它提供类，源和javadoc，如下所示：

I am using JShell to test a library for which I made classes, sources, and javadoc available through the class path like so:

jshell --class-path library-javadoc.jar:library-sources.jar:library-jar-with-dependencies.jar

但是，当我收到记录的Java标识符之后的双标签时：

Still, when double tab after a documented Java identifier I receive:

<no documentation found>

JShell如何期待文档？

How does JShell expect the documentation?
