Hi,

I am new to Soot and I tried the following code:

public class mytry
{
	public static void main(String[] args) {
		args = new String[] {"VeryBusyClass"};
		
		if (args.length == 0) {
			System.out.println("Usage: java RunVeryBusyAnalysis class_to_analyse");
			System.exit(0);
		}
	Options.v().set_soot_classpath("/home/abhijit/Desktop/soot/nightly_build/soot_10th_jan_2019/");	
   		Options.v().set_keep_line_number(true);
		SootClass sClass = Scene.v().loadClassAndSupport(args[0]);		
		sClass.setApplicationClass();
		
		Iterator methodIt = sClass.getMethods().iterator();
		while (methodIt.hasNext()) {
			SootMethod m = (SootMethod)methodIt.next();
			Body b = m.retrieveActiveBody();
			
			System.out.println("=======================================");			
			System.out.println(m.toString());
		}
	}
}

Running this command :
java -cp sootclasses-trunk-jar-with-dependencies.jar:.:/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar mytry

The error is:

Exception in thread "main" soot.SootResolver$SootClassNotFoundException: couldn't find class: 
java.lang.Object (is your soot-class-path set properly?) Try adding rt.jar to Soot's classpath, e.g.:
java -cp sootclasses.jar soot.Main -cp .:/path/to/jdk/jre/lib/rt.jar <other options>
	at soot.SootResolver.bringToHierarchyUnchecked(SootResolver.java:232)
	at soot.SootResolver.bringToHierarchy(SootResolver.java:214)
	at soot.SootResolver.bringToSignatures(SootResolver.java:279)
	at soot.SootResolver.processResolveWorklist(SootResolver.java:172)
	at soot.SootResolver.resolveClass(SootResolver.java:134)
	at soot.Scene.loadClass(Scene.java:942)
	at soot.Scene.loadClassAndSupport(Scene.java:927)
	at mytry.main(mytry.java:37)

Can you please help me out with understanding what's going wrong here. How can I load the rt.jar?

Thanks and regards,
Abhijit

Soot complains that it cannot find any source for the java.lang.Object class. You can either add the rt.jar to Soot's class path explicitly (as stated in the error message): java -cp sootclasses-trunk-jar-with-dependencies.jar:.:/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar soot.Main -cp .:/path/to/jdk/jre/lib/rt.jar mytry. Or you use the -prepend-classpath option that will add your java class path to Soot's: java -cp sootclasses-trunk-jar-with-dependencies.jar:.:/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar soot.Main -pp mytry
