cider repl error ClassNotFoundException: jdk.javadoc.doclet.Doclet

in CIDER by

Hello Everyone,

I have started learning clojure. Using the book "clojure for the brave and true".
I am trying to get the first code running using emacs, cider.

Whenever I run
M-x cider-jack-in

to start the repl. It starts then I get a very long error stack trace.
From the analysis I have done. It appers the error is caused

by Caused by: java.lang.ClassNotFoundException: jdk.javadoc.doclet.Doclet

I am using
jdk 11.0.14
clojure 1.11.1
cider 1.6.0

Find below the stack trace

I'm sorry you are seeing this error. I've done a little googling and found this issue: https://github.com/clojure-emacs/orchard/issues/117

It seems some jdks have the javadoc classes removed. CIDER (via its dependency orchard) uses these classes to parse java classes.

Can you tell me the output of java -version and how you installed java? For instance, for me my output is

❯ java -version
openjdk version "17.0.1" 2021-10-19 LTS
OpenJDK Runtime Environment Zulu17.30+15-CA (build 17.0.1+12-LTS)
OpenJDK 64-Bit Server VM Zulu17.30+15-CA (build 17.0.1+12-LTS, mixed mode, sharing)

And i installed it with sdkman.

by
java -version
openjdk version "11.0.14" 2022-01-18
OpenJDK Runtime Environment Temurin-11.0.14+9 (build 11.0.14+9)
OpenJDK 64-Bit Server VM Temurin-11.0.14+9 (build 11.0.14+9, mixed mode)

I am using a windows 64 bit laptop.
I downloaded the open jdk from this link

AdoptOpenJDK

https://adoptopenjdk.net/

The installer that was used is located at this link
https://adoptium.net/en-GB/temurin/releases/?version=11

Thanks for giving me a hint. I decided to change the jdk that lein is using by adding JAVA_CMD environment.  C:\Program Files\Java\jdk1.8.0_231\bin\java.  (Switched to jdk 8 instead of the default jdk 11). It's working now. This will allow me to continue learning for now. I still want to use jdk 11 for production apps so I will still have to fix this issue in the future.

I found this link helpful on how to switch jdk lein is using.
