Components Example

[Simonl9l]

Trying to understand components. Look like it has lots of potential for our use case (s) - lot's of similar builds!

per the Parameters I'm looking to access the solution, but [Solution] Solution Solution => TryGetValue(() => Solution)!; comes back with null?

I see in the link above, that Solution is defined as string, however that mean I can then get to the Solution properties?

Am I also supposed to define [Solution] Solution Solution; in the main Build.cs file too?

I'm getting a No solution file defined for 'Solution'. exception?

here is the Component:

[ParameterPrefix(nameof(IBuildRestore))]
public interface IBuildRestore : INukeBuild
{
    [Solution] Solution Solution => TryGetValue(() => Solution)!;
 
    public Target Restore => _ => _
        .Executes(() =>
    {
        Log.Debug(Solution);
    }); 

here is the build:

class Build : NukeBuild, IBuildRestore 
{
    public static int Main () => Execute<Build>(x => x.DoBuild);
   
    [Solution] Solution Solution;
        
    public Target DoBuild => _ => _
        .DependsOn<IBuildRestore>(t => t.Restore)
        .Executes(() =>
        {
            Log.Debug(Solution);
        });
}

here is the error:

12:45:37 [WRN] Could not inject value for IBuildRestore.Solution
System.ArgumentException: No solution file defined for 'Solution'.
   at Nuke.Common.Assert.NotNull[T](T obj, String message, String argumentExpression) in /_/source/Nuke.Utilities/Assert.cs:line 73
   at Nuke.Common.ProjectModel.SolutionAttribute.GetSolutionFileFromParametersFile(MemberInfo member) in /_/source/Nuke.Common/Attributes/SolutionAttribute.cs:line 83
   at Nuke.Common.ProjectModel.SolutionAttribute.GetValue(MemberInfo member, Object instance) in /_/source/Nuke.Common/Attributes/SolutionAttribute.cs:line 53
   at Nuke.Common.ValueInjection.ValueInjectionAttributeBase.TryGetValue(MemberInfo member, Object instance) in /_/source/Nuke.Build/Execution/Extensibility/ValueInjectionAttributeBase.cs:line 26

from the Build - the Solution is correctly returned:

[DBG] /{file system path}/NukeConstructs.sln

Is there a comprehensive working example I can crib from - as Im obviously missing something from the documentation?

On review of this, it seems that this is directly setting the interfaces Solution property, where as the understandings is that is what the TryGetValue(() => Solution) is supposed to do?
