I also could not install using the gradlew steps. Build fails..

[askua]

maybe you should set a proxy for gradlew？
you can try.
and the gradlew’ version could not too high because the author of the source code repo. There are so many different dependents.

@nsankar I'm having the exact same issue, have you found a solution?

Same issue here, something to do with gradle ?

@nsankar @davisjm4 @yashj1301 @TDClarke
Maybe you could set a proxy sever for gradlew tool.
like https://michlstechblog.info/blog/gradlew-using-gradlew-behind-a-http-proxy-server/

and build again in cmd.

use command line
gradlew installkernel --stacktrace --info --python D:\Python37\python3.exe

From the plugin README:

• Install path configuration:
  • --python PYTHON: Set the python executable to use for resolving the sys.prefix.
• Install path:
  • --default: Install for all users.
  • --user: Install to the per-user kernel registry.
  • --sys-prefix: Install to Python's sys.prefix. Useful in conda/virtual environments.
  • --prefix PREFIX: Specify a prefix to install to, e.g. an env. The kernelspec will be installed in PREFIX/share/jupyter/kernels/.
  • --path PATH: Set the path to install the kernel to. The install directory is $path/$kernelName.
  • --legacy: Install to $HOME/.ipython. Not recommended but available if needed.

For example if your python installation is called python3.7, use ./gradlew installKernel --python python3.7.

may lated to jdk version, jdk 11 works, but 17 failed due to unsupported gradle version
