Hello
I would like to use the Abstract syntax tree of eclipse in order to count the number of methods, casts, etc in java classes
but until now, I'm not able to run any example using the AST
I would like to run the following example:
package astexplorer;
import org.eclipse.jdt.core.dom.*;
import org.eclipse.jface.text.Document;
import org.eclipse.text.edits.TextEdit;
public class Test{
public static void main(String[] args){
Test t= new Test();
t.runtest();
}
void runtest(){
Document doc = new Document("import java.util.List;\nclass X {}\n");
ASTParser parser = ASTParser.newParser(ASTParser.K_COMPILATION_UNIT);
parser.setResolveBindings(true);
parser.setSource(doc.get().toCharArray());
CompilationUnit cu = (CompilationUnit) parser.createAST(null);
cu.recordModifications();
AST ast = cu.getAST();
ImportDeclaration id = ast.newImportDeclaration();
id.setName(ast.newName(new String[] {"java", "util", "Set"}));
cu.imports().add(id); // add import declaration at end
TextEdit edits = cu.rewrite(doc, null);
}
}
first, I found problems to know what jars I have to include to my project.
then, I added the following jars :
aspectjtools-1.2.jar
core-3.2.0.658.jar
eclipse-jface-2.1.0.jar
swt.jar
but I still have problems with
mpilationUnit) parser.createAST(null);
and
I've got a compilation error indicating that the methods are undefined for the type CompilationUnit
Could you indicate to me if I added the right jars and if I have to do other thigs in order to use The AST of eclipse.
thank you

You need more than that.
The best way to know what jars you need is to select org.eclipse.jdt.core inside a launching configuration and click on Add required bundles.
That way you should get a list of all bundles required to run the org.eclipse.jdt.core bundle.
