[BUG] 修改文件，发现 fileServiceClient.onFilesChanged 会触发 2 次 #4628

import { IFileServiceClient, IFileServiceWatcher } from '@opensumi/ide-file-service';

@Injectable()
@Domain(ClientAppContribution)
export class CompileServiceClient extends RPCService implements ICompileServiceClient, ClientAppContribution { 
  @Autowired(IFileServiceClient)
  private readonly fileService: IFileServiceClient;

 private fileWatcher: IFileServiceWatcher | undefined;

  onDidStart() {
    // 创建文件监听器
    this.fileWatcher = await this.fileService.watchFileChanges(new URI(projectPath), [
      '**/node_modules/**',
      '**/dist/**',
      '**/.git/**'
    ]);

    this.fileWatcher.onFilesChanged((events) => {
      // ❓问题点：修改被 fileService watch 目录里面任意文件，回调都会触发2次
    })
  }
}
