Omnisharp-vscode: The terminal shell path "dotnet" is a directory

[abaga129]

Issue Description

Cant run "build" task because "The preLaunchTask 'build' terminated with exit code -2."

I've narrowed it down to the following The terminal shell path "dotnet" is a directory. Changing the build task to have a direct path to the dotnet executable works.

Before (Error)

{
    "label": "build",
    "command": "dotnet",
    "type": "process",
    "args": [
    "build",
    "${workspaceFolder}/ProcessedSaleWatcherService.csproj",
    "/property:GenerateFullPaths=true",
    "/consoleloggerparameters:NoSummary"
    ],
    "problemMatcher": "$msCompile"
},

After (Works)

{
    "label": "build",
    "command": "/home/ethanpreker/.dotnet/dotnet",
    "type": "process",
    "args": [
    "build",
    "${workspaceFolder}/ProcessedSaleWatcherService.csproj",
    "/property:GenerateFullPaths=true",
    "/consoleloggerparameters:NoSummary"
    ],
    "problemMatcher": "$msCompile"
},

Steps to Reproduce

Install dotnet sdk 3.0 on linux using dotnet-install.sh script.

./dotnet-install.sh -Channel Current

Add path to .bashrc or .zshrc

export PATH=$PATH:/home/ethanpreker/.dotnet

Run build task in vscode (ctrl + shift + B)

Expected Behavior

The project will build correctly

Actual Behavior

> Executing task: dotnet build /home/ethanpreker/Repos/ProcessedSaleWatcherService/ProcessedSaleWatcherService.csproj /property:GenerateFullPaths=true /consoleloggerparameters:NoSummary <

The terminal shell path "dotnet" is a directory

Terminal will be reused by tasks, press any key to close it.

[JoeRobich]

Hi @abaga129,
Sorry you ran into this. It seems you were able to fix this by making sure dotnet was on your path, which is what we expect.
-Joey

[abaga129]

It's not exactly fixed. I have to change my tasks to have a hardcoded path to the dotnet binary e.g. "command": "/home/ethanpreker/.dotnet/dotnet". This would be okay except that when someone else pulls my code and tries to run it, they wont have dotnet at the same path. Is there some way I make it work with "command": "dotnet",?

Thanks for your time

[auspex]

I agree, this is _not_ fixed and should not be closed! Every time I create a project, I have to go in and hardcode the path to the dotnet executable.

[auspex]

Further, if I use F5 to build the project, I get this error message, but if I open a terminal and use
dotnet build it works fine.

[auspex]

The true error is that the tasks.json file is being built with "type": "process" rather than "type": "shell" https://github.com/microsoft/vscode/issues/79346 gets this wrong, too, but I can't comment on that. Thanks to https://stackoverflow.com/a/58486984/334719

[abaga129]

Thanks @auspex! That did the trick for me as well! I guess now this issue can be closed sarcasm

[rishitc]

The true error is that the tasks.json file is being built with "type": "process" rather than "type": "shell" microsoft/vscode#79346 gets this wrong, too, but I can't comment on that. Thanks to https://stackoverflow.com/a/58486984/334719

Just wanted to mention that in my case changing process to shell actually made it work error-free. I didn't have to change anything else in the tasks.json file.
