Error locating module crux.kv.index-store/->kv-index-store

[luposlip]

After updating from 1.16.0 to 1.17.0 I get a new error from my unit tests.

Previously I've initialized a "mock" node by just passing an empty configuration map to crux.api/start-node. Which worked fine.

With 1.17.0 I get the following error:

Hey @luposlip :) I'm a little surprised by this one, we use (crux/start-node {}) in a lot of tests. Couple of quick questions:

• What JDK version are you using? We've fixed a JDK16 bug recently and released a dev-SNAPSHOT - if you're also using JDK16+, would you mind testing against that snapshot?
• Otherwise, do you get any other errors trying to (require 'crux.kv.index-store)?

Cheers,

James

Hi @jarohen - yeah, me too. I'm using JDK 11 (AdoptOpenJDK 11.0.11+9 Hotspot).

I've also tried with GraalVM JDK 11.

Both JDK's give same issue.

I can require crux.kv.index-store without issues.

I am hitting something similar to this, exception below this is a very basic setup using (crux/start-node {}) it works on my machine but not when run inside docker using image: clojure:tools-deps and launching like so java -jar target/demo.jar

I am using juxt/crux-core {:mvn/version "RELEASE"} in my deps file.

[olymk2]

switched to image: clojure:openjdk-11-tools-deps seems to fix it so I guess its an issue with the newer jdk versions

[jarohen]

Fix released as part of "1.18.0-rc1" :rocket:

For the record - if anyone else experiences this going forward - a simple cleaning (i.e. remove the target folder) might fix this issue.
