How to get the return type or parent class of method invocations within a workspace? - exception

Question

I have to get the return types or the parent class of method invocations to distinguish between overloaded methods within a workspace. I am currently using javaparser to do the same, however I encountered unresolved symbol exceptions with certain method calls that I observed to be defined within the same class that they were being used in (with exception of a few). The directory given to the JavaParserTypeSolver is the src directory of the project containing the class. A snippet for the part is as follows -
for(ICompilationUnit unit : units) {
File file = new File(workspacePath+pack.getPath()+"\\" + unit.getElementName());
CombinedTypeSolver solver = new CombinedTypeSolver();
solver.add(new ReflectionTypeSolver());
solver.add(new JavaParserTypeSolver(projectPath + "/src"));
TypeSolver typeSolver = solver;
JavaSymbolSolver symbolSolver = new JavaSymbolSolver(typeSolver);
StaticJavaParser.getConfiguration().setSymbolResolver(symbolSolver);
CompilationUnit cu = StaticJavaParser.parse(file);
}
The output showing the methods that it is encountering exceptions with -

As I mentioned earlier, most of these methods are particularly the ones that are defined within the class itself.
I want to know if I am missing something or doing it wrong. Any alternatives to achieve the same would also be appreciated.
