问题部分中的VSCODE扩展堆叠输出

Question

有人可以给我一个提示，为什么vScode多次运行时，Vscode在问题部分中堆放了输出（在我们的自制作Vscode扩展程序中，来自同一文本文件）？

类定义：

import {  Uri, languages, Range, Diagnostic, Position, DiagnosticCollection } from "vscode";

export class ProblemHelper{

   public rangeObj: Range | undefined; 
   public  problemObj: Diagnostic | undefined;
   public problemEntries: Array<Diagnostic> = [];

   //public static diagnosticCollection: DiagnosticCollection;
   constructor(actDocument: Uri| undefined,message: string, severity: number){

     console.log("problemhelper const 0 " + this.problemEntries.length);
     this.rangeObj = new Range(new Position(1,1),new Position(1,1) );
     this.problemObj = new Diagnostic(this.rangeObj,message,severity );
     this.problemObj.source = actDocument?.fsPath;
     this.problemEntries.push(this.problemObj);
     console.log("problemhelper const 1 " + this.problemEntries.length);      
  }

  public  setProblems(actDocument: Uri, coll: DiagnosticCollection, mess: string, sev: number) {
      this.problemEntries.forEach(e => {
          if (this.problemObj?.message === e.message) { 
             return;
          }
      });
      this.rangeObj = new Range(new Position(1,1),new Position(1,1) );
      this.problemObj = new Diagnostic(this.rangeObj,mess,sev );
      this.problemEntries.push(this.problemObj);
      console.log("problemhelper const 3 "  + this.problemEntries.length);
      coll.set(actDocument,this.problemEntries);
      console.log("problemhelper const 4 " + coll.get(actDocument)?.length);
      //ProblemHelper.diagnosticCollection!.set(actDocument,ProblemHelper.problemEntries);
  }

  public deleteProblems(actDocument: Uri | undefined, coll: DiagnosticCollection) {
       console.log("in delete before " + this.problemEntries.length);
       coll.delete(actDocument!);
       this.problemEntries = [];
       console.log("in delete after " + this.problemEntries.length);
       //coll.dispose();
   }

}

与：

const diagnosticCollection = languages.createDiagnosticCollection(window.activeTextEditor?.document.uri.fsPath);
let temp = new ProblemHelper(window.activeTextEditor?.document.uri,"test", 0);
temp.deleteProblems(window.activeTextEditor?.document.uri,diagnosticCollection);

temp.setProblems(window.activeTextEditor?.document.uri!,diagnosticCollection,"test1",1);
    
temp.setProblems(window.activeTextEditor?.document.uri!,diagnosticCollection,"test222",2);
console.log("end");

在调试控制台中输出（屏幕截图）来自“扩展开发主机”，可以看出正确的条目数量，但每次都会堆叠起来）：

problemhelper const 0 0
problemhelper const 1 1
in delete before 1
in delete after 0
problemhelper const 3 1
problemhelper const 4 1
problemhelper const 3 2
problemhelper const 4 2
end
problemhelper const 0 0
problemhelper const 1 1
in delete before 1
in delete after 0
problemhelper const 3 1
problemhelper const 4 1
problemhelper const 3 2
problemhelper const 4 2
end

VSCODE版本：1.66.0（Win 10）

谢谢！

非常感谢您，您是对的，我完成了两次新课程，所以我在Extension Startup上运行此课程，然后Do clear（）而不是删除（xx）。现在我可以前进。
