MSB1001: Unknown switch; Switch: --project

[Denovocto]

Describe the bug

When using the dotnet cli, using dotnet run --project <project_name> and dotnet build --project Bioportal.API,
MSBuild Fails with error:
MSBUILD : error MSB1001: Unknown switch.. Sometimes it runs flawlessly without error and other times it says build failed.
I've tried starting new shell sessions, new terminal sessions, restoring projects, none seem to fix the error.

To Reproduce

Currently using MSBuild version 17.4.0-preview-22428-01+14c24b2d3 and .NET 7.0.100-rc.1.22431.12.
The full default commandline flags are: -maxcpucount, verbosity:m, -restore, -consoleloggerparameters:Summary.

Below that error, this information is shown:
Switches appended by response files:
Switch: --project`

Exceptions (if any)

IDE / Editor

Just using alacritty as terminal and zsh as shell. Error appears only in cli.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

--project is only supported for the dotnet run command, so it doesn't surprise me that build doesn't seem to have the option.

Can you clarify the exact commands/sequence of command you're running? I'm not entirely sure how to repro here.

[Denovocto]

I ran the project using dotnet run --project <project_name>, and the build fails, so I then ran the build to see what was wrong. But thing is that there are no build errors when I build with Rider IDE, no linting errors either, only when I use the cli that error occurs. As I mentioned above, sometimes when I run the command again, it just runs without any error.

[Denovocto]

I have now realized that, as mentioned by @baronfel, the build option doesn't support --project. Sorry for the confusion, but still, my build is failing with (0 warnings) and (0 errors).
build output:

MSBuild version 17.4.0-preview-22428-01+14c24b2d3 for .NET

@Denovocto would you consider uploading a binlog to help us track down the issue?

[Denovocto]

build.zip
Here it is. Had to upload it as a zip.

[baronfel]

@Denovocto can you set the environment variable DOTNET_CLI_DO_NOT_USE_MSBUILD_SERVER to 1 and try again?

[Denovocto]

I did it. Now it succeeds. Why is that? Is it related to issue #7914

[baronfel]

@rokonec @MichalPavlik @AR-May can you all look into this potential MSBuild server issue?

[rokonec]

@Denovocto It might be related to #8010 and is already being fixed by #8006.
Above bug would have surfaced if you attempted to cancel build, CTRL+C, some short time, max 15 minutes, before. Have you?
