out of scope: Is it actually fine to create a new instance of Pip each time? (IIRC dependency graph building relies on using only once instance)

IIRC dependency graph building relies on using only once instance

Actually, the requirement is that not multiple package managers that manage the same project type are enabled at the same time:

ort/model/src/main/kotlin/DependencyGraphNavigator.kt

Lines 48 to 55 in b2e6c3d

	// TODO: Relax this assumption that package manager names start with the name of the type of project
	// they manage, for example that "GradleInspector" manages "Gradle" projects.
	val managers = graphs.keys.filter { it.startsWith(project.id.type) }
	val manager = requireNotNull(managers.singleOrNull()) {
	"All of the $managers managers are able to manage '${project.id.type}' projects. Please enable only one " +
	"of them."
	}

So, as this commit fixes the multiple Pip instances to have different project types, we should be good.

Hm, I believe I was after a different requirement, was it that same DependencyGraphBuilder or Handler instance needs to be used, maybe?

[sschuberth]

No idea...
