There is no task provider registered for tasks of type "cargo" for VSCode workspace, again

[CrendKing]

I'm experiencing the exact same issue as #9093, but in the latest version. The previous 0.3.1885 does not have issue.

rust-analyzer version: 0.3.1896

rustc version: 1.77.0 stable

Same here.
Using the same Rustc and Analyzer version.

Using VSCodium on Linux.

I didn't change anything in my project configuration, today it does not build using Ctrl+Shift+B or explicitly entering "Run: Tasks" -> "rust: cargo build" and the error is shown for me as well.

However, clicking the "Run", "Debug" and "Run Tests" hyperlinks shown inside the code editor above main and tests does still work and also F5 to start debugging (which I have configured to launch with LLDB) works as always.

So it seems quite specifically related to the cargo build task.

Same too.

Likewise, experiencing this issue :(

The previous 0.3.1885 does not have issue.

Are you sure? I get the same error in v0.3.1868 and v0.3.1885.

Same issue, vscode with RA 0.3.1896 (on Linux 6.5.0-26), no issue on 0.3.1885

Can anyone bisect this?

Can anyone bisect this?

Hmmm … now I've built a binary to check, but how do I use it with my VSCode?

git checkout "2024-03-25"
git bisect start
git bisect bad
git bisect good "2024-03-18"
cargo build --release

cargo xtask install will install it to ~/.cargo/bin and also build and install the Code extension. Make sure you have nodejs and npm and you'll need to restart Code to make sure it's using the new one (i.e. don't trust "Reload window").

This refers to commit 2e109c7, but someone deeper involved should take it from here, I know nothing about the vscode extension API.

I wonder why these were broken for me though.

[Wilfred]

Thanks for the ping, I'll take a look. Sorry about this.

[Wilfred]

OK, this is an issue with how tasks are defined, because they're a user-facing API through tasks.json or .code-workspace.

If you need a workaround right now and can't downgrade, you can define your task as a shell command:

{
	"version": "2.0.0",
	"tasks": [
		 {
			"type": "shell",
			"command": "cargo build",
			"problemMatcher": [
			  "$rustc"
			],
			"group": "build",
			"label": "my example cargo build task"
		 }
	]
}

I think there's another issue with the task declaration in package.json, it doesn't allow cwd at all. That looks like a pre-existing problem though.
