How to build a .sln file using mdtool on OS X - macos

Question

I'm trying to compile a .sln file within /SteamBot-master/SteamBot.sln.
After research I found out that I can only use mdtool within the mdtool directory within Xamarin Studio. So what I enter into the Terminal is the following:
"/Applications/Xamarin\ Studio.app/Contents/MacOS/mdtool" -v build SteamBot-master/SteamBot.sln
This is the error message I get:
-bash: /Applications/Xamarin\ Studio.app/Contents/MacOS/mdtool: No such file or directory
The mdtool.exec application is within the MacOS file, I already checked that. When I try to run the application within Xamarin Studio, I get the following error:
/Users/Johannes/SteamBot-master/.nuget/NuGet.targets: Error: Command 'bash "/Users/Johannes/SteamBot-master/.nuget/../.ci/exec-with-retry.sh" mono --runtime=v4.0.30319 /Users/Johannes/SteamBot-master/.nuget/NuGet.exe install "packages.config" -source "" -RequireConsent -solutionDir "/Users/Johannes/SteamBot-master/"' exited with code: 127. (SteamTrade)
I'd really appreciate if someone could help me fix this so I can use the application. Thank you very much in advance, and I apologize for my lack of programming knowledge.
Edit: New Error Message

Answer 1

I am assuming you are using the SteamBot source code from GitHub:
https://github.com/Jessecar96/SteamBot
The .ci/exec-with-retry.sh file is missing since this is part of the continuous integration build and it is not on GitHub.
Probably the simplest workaround is to edit the .nuget/NuGet.targets file and change the following line:
<RestoreCommand Condition=" '$(OS)' != 'Windows_NT' ">bash "$(NuGetToolsPath)\..\.ci\exec-with-retry.sh" $(NuGetCommand) install "$(PackagesConfig)" -source "$(PackageSources)" $(RequireConsentSwitch) -solutionDir "$(SolutionDirParsed)"</RestoreCommand>
To:
<RestoreCommand Condition=" '$(OS)' != 'Windows_NT' ">$(NuGetCommand) install "$(PackagesConfig)" -source "$(PackageSources)" $(RequireConsentSwitch) -solutionDir "$(SolutionDirParsed)"</RestoreCommand>
This just removes the reference to the file and to bash.

Answer 2

The problem is that you have effectively double-escaped the space. Either enclose a command with spaces in it inside double quotes, or put a backslash in front of each space, but not both!
Use either of these:
/Applications/"Xamarin Studio.app"/Contents/MacOS/mdtool ...
or
/Applications/Xamarin\ Studio.app/Contents/MacOS/mdtool ...
