Build fails on Windows

[MichaelMauderer]

I was just trying to build the newest develop on Windows, and the build failed with the following error:

Error: Failed to build Wasm.

Caused by:
    Cannot create a file when that file already exists. (os error 183)

This was a fresh build started with ./run.cmd ide watch --backend-source=release --backend-release=latest --skip-wasm-opt and using cargo watch plus.

Just before, the build seemed to be creating the precompiled shaders, which seemed to be going on for quite a while.

@MichaelMauderer It's a known bug, unfortunately. Try again, it should work after any change to the code. Please confirm if it works on your end.

[MichaelMauderer]

Changed some code and did a rebuild, but it failed the same way.

[MichaelMauderer]

Okay, after another clean rebuild and it worked. But this is an ugly bug costing a lot of time.

[wdanilo]

@mwu-tow do we have any insights here?

[mwu-tow]

@wdanilo Not really, no. The first step would be fixing the ensogl-pack to use build-script-style FS access, so we at least get better logs.

@MichaelMauderer I wonder… Does this ever happen without cargo watch plus? Both you and @wdanilo use it, and both of you encountered this issue.

[wdanilo]

That's good question. I haven't see this error for a LONG time tbh. @MichaelMauderer are you using cargo watch plus?

[MichaelMauderer]

Yes, I was using cargo watch plus there.

[MichaelMauderer]

But I just got the error on Linux without cargo watch plus, too.
