Recommendations on variations of build components that need to be used in the same build?

[forrestab]

I have a situation where I need to run restores for dotnet, npm and bower during a build. I was thinking of using build components for this because we have other projects that have these same requirements.

Originally I thought of something like below.

interface IRestore
{
    Target Restore => _ => _.Executes(() => Log.Information("Base restore"));
}

interface IDotNetRestore : IRestore
{
    Target IRestore.Restore => _ => _
        .Inherits<IRestore>()
        .Executes(() => Log.Information("DotNet restore"));
}

interface INpmRestore : IRestore
{
    Target IRestore.Restore => _ => _
        .Inherits<IRestore>()
        .Executes(() => Log.Information("Npm restore"));
}

class Build : NukeBuild, INpmRestore, IDotNetRestore
{
    Target RestoreTask => _ => _.DependsOn<IRestore>();
}

But that runs into c# problems where it doesn't know which Restore target to execute (I believe its called the "diamond problem").

Maybe Im doing something dumb or I just don't understand the nuke api well enough yet, but is there a way to achieve my goal or maybe a better recommendation?

You should introduce separate targets for that – RestoreDotNet, RestoreNpm, ...

One example could work like this (for illustration without components):

Target Restore => _ => _;

Target Compile => _ => _
    .DependsOn(Restore);

Target RestoreDotNet => _ => _
    .DependentFor(Restore);

Target RestoreNpm => _ => _
    .DependentFor(Restore);
