Win10: An unexpected error occurred when running clj-kondo

[PEZ]

Hello,

I'm trying this on Windows 10 (fully aware that it is not yet supported) mainly to try to get an idea about what the problems might be.

Using the v2019.07.31-alpha version of clj-kondo. I get this in the Clojure Lint output channel:

Clojure Lint extension loaded.
Please report any issues to https://github.com/marcomorain/clojure-lint/issues
An unexpected error occured when running clj-kondo. Please report a bug

[SyntaxError: Unexpected end of JSON input

This does not look to me as a GraalVM problem, but I could be wrong.

I'll do some more looking into this now and will come back if I find out any more.

The problem right now is that clj-kondo, or more accurately GraalVM, has some problems on windows. I clj-kondo itself working with a workaround using WSL.

[PEZ]

But I was right about the above not being a GraalVM problem. It is a problem with quoting the command line arguments, that work differently on Windows.

If I fix that quoting I advance to a new level of problems that might, or might not be GraalVM related:

This error seems to stem from the JSON output format being configured, but I am not sure about that, only had a few moments to test it today. (It could actually be that I haven't got the quoting right yet, just differently wrong. :smile:)

[marcomorain]

@pez do you have a patch for the quoting issue? I’d like to apply that.

[PEZ]

@marcomorain , not really, I just hacked the thing to get me a bit further on my Windows investigation (no regards to still have it working on *nix in that session). :smile:

But I can certainly try to cook a patch for you. I have spent the last two weeks in Windows quoting hell for Calva jack-in so I am somewhat up-to-speed.

[PEZ]

Actually I fail to confirm that this even is a quoting issue. I'll let this be until we have some news about the clj-kondo executable on Windows starting to behave.

[marcomorain]

This is fixed in 0.6.0 using the latest kondo
