How to install native image on Windows

[lispyclouds]

Thanks a lot for this handy action! 😄

I have been happily using this for Mac and Linux but wanted to try out native images for Windows too but im running into the following issues when trying to run gu install native-image:

• If the default shell(Powershell I think?) is used:

  Run gu install native-image
    gu install native-image
    shell: C:\Program Files\PowerShell\7\pwsh.EXE -command ". '{0}'"
    env:
      JAVA_HOME: C:\hostedtoolcache\windows\GraalVM\20.3.0-java11\x64
      JAVA_HOME_20.3.0.java11: C:\hostedtoolcache\windows\GraalVM\20.3.0-java11\x64
      LEIN_HOME: C:\hostedtoolcache\windows\Leiningen\2.9.5\x64
  Get-Unique: D:\a\_temp\1a3e4b20-ff2e-4c1f-8c67-4f71f6a61b6e.ps1:2
  Line |
     2 |  gu install native-image
       |  ~~~~~~~~~~~~~~~~~~~~~~~
       | A positional parameter cannot be found that accepts argument 'install'.
  
  Error: Process completed with exit code 1.
  

• If I use shell: bash

  Run gu install native-image
    gu install native-image
    shell: C:\Program Files\Git\bin\bash.EXE --noprofile --norc -e -o pipefail {0}
    env:
      JAVA_HOME: C:\hostedtoolcache\windows\GraalVM\20.3.0-java11\x64
      JAVA_HOME_20.3.0.java11: C:\hostedtoolcache\windows\GraalVM\20.3.0-java11\x64
      LEIN_HOME: C:\hostedtoolcache\windows\Leiningen\2.9.5\x64
  D:\a\_temp\9fd80673-7852-483b-9f69-b700b89aafdc.sh: line 1: gu: command not found
  Error: Process completed with exit code 127.
  

This is my YAML

- name: Setup GraalVM
  uses: DeLaGuardo/setup-graalvm@master
  with:
    graalvm-version: '20.3.0.java11'
- name: Setup Leiningen
  uses: DeLaGuardo/setup-clojure@master
    with:
      lein: 2.9.5
- name: Install native image toolchain
  shell: bash # Or without this
  run: gu install native-image # This is what fails

I tried setting up the PATH manually too but my limited Windows skills are failing me miserably 🙁

[DeLaGuardo]

I'll have a look. Probably you right and this is just misconfiguration so should be easy to fix

[DeLaGuardo]

To install additional components on windows you can use gu.cmd instead of gu
however, I don't know yet why there is a difference between windows and other platforms (they all should work the same) :(

By default, windows has an alias named 'gu' for Get-Unique command

[dermoritz]

what is "gu" and how to install it on windows?

[DeLaGuardo]

@dermoritz it is a command line tool called GraalVM updater - https://www.graalvm.org/latest/reference-manual/graalvm-updater/

I recommend using official action from graalvm and this is how you can use gu on windows - https://github.com/graalvm/setup-graalvm/blob/main/.github/workflows/test.yml#L119-L126
