Test projects are not excluded with option "exclude-test-projects"

[AlbertoMonteiro]

Opening a new issue because the previous one was closed, but didnt fixed all the cases as I explained in my comment:
#363 (comment)

Please add the property <IsTestProject>true</IsTestProject> in the test csproj file. As far as I know cyclonedx-dotnet does not merge all props and target files.

I can confirm this bug. In Directory.Build.Props we set the property IsTestProject to all test projects:

	<PropertyGroup Condition="$(MSBuildProjectName.EndsWith('.Tests')) or $(MSBuildProjectName.EndsWith('.IntegrationTests'))">
		<IsPackable>False</IsPackable>
		<IsTestProject>True</IsTestProject>
	</PropertyGroup>

But during the run it was analyzed even though we called it with the option to ignore test projects. When we set it directly in the csproj file, it is skipped as expected.

The cyclonedx-dotnet tool uses solution, project and intermediate output file project.assets.json. The tool is executed after a build is executed and does not use or create any derived project property settings from build target.

Therefore the definition of the IsTestProject property in a *.props or *.target file which is resolved during build target execution cannot be used for the exclude-test-projects option.

This limitation for exclude-test-projects option should be documented in README.md.

--exclude-test-projects option resolves IsTestProject property value from project file after a build is executed. Therefore <IsTestProject>true</IsTestProject> shall be defined in csproj file or in an explicit import property file within the csproj file without conditions.

This is technically understood - but from a user perspecitve I am now forced to apply an error prone + manual process (to add the flag everywhere and don't forget that in the future) where there is already a better and central place.

What about having an --ignore-pattern commandline paramter, where I can specify pattern to ignore projects that should not be scanned?

[Bertk]

A new feature with a command line option filter projects could solve it but the list of options is already pretty huge.

Anyway, #736 might be a better solution which also allows to eliminate some low level XML document handling.

This issue is stale because it has been open for 3 months with no activity.
