JJava kernel does not start in VSCode Jupyter

[emcastro]

Probable bug in Jupyter Extension for VSCODE
microsoft/vscode-jupyter#16344

Workaround
Replace {resource_dir} in kernel.json by its actual value.

One can install the JJava kernel using this script:

#!/bin/bash

set -e

version=1.0-a4 # Choose the one you wish

# Download
wget https://github.com/dflib/jjava/releases/download/${version}/jjava-${version}-kernelspec.zip --output-document=jjava-kernelspec.zip

# Install
mkdir -p "${HOME}/.local/share/jupyter/kernels/java"
unzip -o -d "${HOME}/.local/share/jupyter/kernels/java" jjava-kernelspec.zip 
rm jjava-kernelspec.zip

# Fix
sed -i "s|{resource_dir}|$HOME/.local/share/jupyter/kernels/java|g" "${HOME}/.local/share/jupyter/kernels/java/kernel.json"

echo -e "Restart VSCode before using the JJava kernel"

Thanks for reporting the issue and a possible solution. We'd like to support VSCode better. It seems like a very different beast from browser-based Jupyter clients (e.g. dflib/dflib#410 ). Wish it had more developer-oriented docs.

Jupyter Extension supports {resourse_dir} now. This one may be closed.

@m-dzianishchyts , cool! Let's wait till they actually release that at the end of February, and then we'll close it
