GitVersion should rely on existing dotnet SDKs rather than downloading it using brew

[iamNoah1]

I recognized that when I install GitVersion using brew on macos, it downloads a separate dotnet SDK using brew as well. Instead, it should rely on the existing one.

Detailed Description

I faced a problem that after installing GitVersion using brew, my Visual Studio Code Omnisharp could not find the installed SDKs anymore.

After doing some research, I deleted dotnet using brew and reinstalled dotnet using the official installer. After that my Visuals Studio Code Omnisharp found the SDK again, but my GitVersion was not working anymore.

I assume that installing GitVersion using brew, not only installs dotnet via brew, but also changes Environment that is responsible for pointing to a specific dotnet SDK version when invoking the dotnet command. Probable it changes the PATH in a way that the dotnet version installed via brew gets found first, before the one installed via the official installer.

Context

The importance of this is the following. With the described scenario I had to choose if I want to have GitVersion working or my Visual Studio Code Omnisharp. Both were not working at the same time. I had to create a symlink in order to tell GitVersion to use the SDK installed via the official installer.

sudo mkdir -p /usr/local/opt/dotnet/bin
sudo ln -s /usr/local/share/dotnet/dotnet /usr/local/opt/dotnet/bin/dotnet

Possible Implementation

• Installing dotnet as well could be made optional using a flag
• The SDK could be specified using an Env variable
• GitVersion could first check if there is any dotnet SDK already installed before wanting to install a fresh one

@asbjornu can you check that?

Homebrew can't set environment variables globally on your machine on install and installs formulae to a different path than the official installer so you would need to adjust the DOTNET_ROOT and PATH to the path Homebrew installs to. This should probably be noted in the Homebrew formula (see Homebrew/discussions#568).

In the meantime, I would advise you to uninstall Microsoft's official SDK, install Homebrew's dotnet formula, and add the following to your ~/.bash_profile or ~/.zshrc file (and remember to source the file to update your current session):

export PATH="$(brew --prefix)/bin:$PATH"
export DOTNET_ROOT="/usr/local/Cellar/dotnet/3.1.108/libexec"

I see, thanks for the info :)

[asbjornu]

Homebrew/homebrew-core#69323 seeks to add this information to the dotnet formula. Please close the issue if you got it working, @iamNoah1.
