Hi @ftomassetti ,
First of all, thank you very much for your explanations in your blog and your examples here. I'm trying to use JavaParser and JavaSymbolSolver to find all the declarations of variables belonging to specific classes (although project-defined ones) and I've started using this example and trying to combine with examples of JavaSymbolSolver in JavaSymbolSolverExamples, but using the build.gradle in this example and adding the dependency for JavaSymbolSolver found the build.gradle of that JavaSymbolSolver examples, I obtain one non-relevant error with node.getBeginLine() and node.getEndLine() methods. The important thing that I'm not able to solve is the use of ReflectionTypeSolver.
As I said before, I'm trying to find the way to search inside all code of one project to obtain all variables of one type. For example, finding all the variables of type javax.swing.JFrame. I would be grateful if you could help me.
