如何在sonarqube插件建树时获取节点访问者的行号

import org.sonar.plugins.java.api.tree.*;

public class MyAstVisitor extends BaseTreeVisitor {

  private List<Integer> lineNumbers = new ArrayList<>();

  @Override
  public void visitNode(Tree tree) {
    if (tree instanceof MethodTree) {
      MethodTree methodTree = (MethodTree) tree;
      int lineNumber = methodTree.simpleName().identifierToken().line();
      lineNumbers.add(lineNumber);
    }
    super.visitNode(tree);
  }

  public List<Integer> getLineNumbers() {
    return lineNumbers;
  }
}
