How can troubleshoot this?

This seems to be a CodeNarc internal error... What is your version of java ?

[UksusoFF]

java --version
openjdk 11.0.21 2023-10-17
OpenJDK Runtime Environment (build 11.0.21+9-post-Ubuntu-0ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.21+9-post-Ubuntu-0ubuntu122.04, mixed mode, sharing)

https://github.com/nvuillam/npm-groovy-lint?tab=readme-ov-file#installation

npm-groovy-lint is supposed to install java 17 if a previous version is found...

Was your first run strangely long ?

What if you try to add --noserver to your npm-groovy-lint call ?

[UksusoFF]

After apt install openjdk-17-jdk openjdk-17-jre and reboot.

First run npm-groovy-lint stuck on CodeNarcServer run without any errors.

Second run produce: GroovyLint: Request cancelled by duplicate call on requestKey undefined

[UksusoFF]

--noserver produce:

ouuuch... seems to require super @stevenh 's knowledge ^^

[stevenh]

Looks like your trying to use a java version, possibly a library, that's compiled with a version of java later that what the code is compiled with, so it can't analyse it.

Can you run the server with debug enabled and post the log file so we can see if it's server or codenarc which is throwing the error.

[UksusoFF]

@nvuillam how I can pass debug enabled to CodeNarc with npm-groovy-lint?

[stevenh]

You can't but if you can run it manually from the command line in another shell npm-groovy-lint will use it instead of starting one.

I am getting similar error, possibly due to my proxy settings, but it makes me paranoid that my non-open-source Jenkinsfile is going to get sent to some off-site server, which is not allowed by my company. Why didn't npm install all pre-reqs? Here's my java output:

$ java --version
Command 'java' not found, but can be installed with:
sudo apt install default-jre              # version 2:1.11-72build2, or
sudo apt install openjdk-11-jre-headless  # version 11.0.20.1+1-0ubuntu1~22.04
sudo apt install openjdk-17-jre-headless  # version 17.0.8.1+1~us1-0ubuntu1~22.04
sudo apt install openjdk-18-jre-headless  # version 18.0.2+9-2~22.04
sudo apt install openjdk-19-jre-headless  # version 19.0.2+7-0ubuntu3~22.04
sudo apt install openjdk-8-jre-headless   # version 8u382-ga-1~22.04.1

using --noserver I still get something about codenarc trying to download and it doesn't seem like it makes any progress:

[████░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░] Running CodeNarc for 0sJava jre or jdk 17 is required
Installing Java jre 17 in /home/user/.java-caller...
[████████████████████████░░░░░░░░░░░░░░░░] Running CodeNarc for 2m3s^C

then I installed java 17 manually with apt: apt install openjdk-17-jre-headless

then I re-run the linter (with --noserver), and I get linting results.

Can't fix this issue on localhost, but run successful in Docker container. So seems this is environment dependent.
