I created a CI pipeline using Nuke that builds my project. On this stage the project throws some warnings that I'd like to ignore, but CI treats them as errors and fails. I want to suppress this behavior. How can I do that? Here is my log.

You need to change <TreatWarningsAsErrors> tag in Directory.Build.props file to false and then everything will work. This error is specific for Nuke.
