Sootup is not able to perform analysis without java dependency

[Liyw979]

When I am generating a call graph without the jdk dependency. I get

Could not find java.lang.Enum in View. ./file-does-not-exist NoPositionInformation
sootup.core.frontend.ResolveException: Could not find java.lang.Enum in View. ./file-does-not-exist NoPositionInformation
	at sootup.core.views.View.lambda$getClassOrThrow$0(View.java:93)
	at java.base/java.util.Optional.orElseThrow(Optional.java:403)
	at sootup.core.views.View.getClassOrThrow(View.java:93)
	at sootup.core.typehierarchy.ViewTypeHierarchy.sootClassFor(ViewTypeHierarchy.java:411)
	at sootup.core.typehierarchy.ViewTypeHierarchy.superClassOf(ViewTypeHierarchy.java:292)
	at sootup.core.typehierarchy.TypeHierarchy.superClassesOf(TypeHierarchy.java:183)
	at sootup.callgraph.AbstractCallGraphAlgorithm.findMethodInHierarchy(AbstractCallGraphAlgorithm.java:271)

For me, a partially constructed call graph(without the jdk) will do the job.

There are throws in many places in the code base like

  @Nonnull
  default T getClassOrThrow(@Nonnull ClassType classType) {
    return getClass(classType)
        .orElseThrow(() -> new ResolveException("Could not find " + classType + " in View."));
  }

Is soot designed for only whole program analysis? (user should provide all dependencies in the setup, and when some dependencies are missing , it stops.)
Or it wants to support partial analysis but there is a misimplementation in CallGraphAlgorithm?

Hi @Liyw979,
we want to support partial analysis as well - unfortunately this is not the current implementation state, yet.
Maybe you like to contribute to SootUp, enabling the CallGraphAlgorithm to create the partially constructed CallGraphs you need.

Which jdk version should I use when developing SootUp?

We use Java8 (Java9 for Java Modules support)
