如何在构建任务中执行shell脚本

import { hapTasks } from '@ohos/hvigor-ohos-plugin'; 
import { exec } from 'node:child_process' 
import util from 'node:util' 
 
// shell脚本地址，相对路径绝对路径均可 
const scriptPath = 'D:\\work_space\\ecological_problem\\test\\entry\\test.bat'; 
 
export function customPluginFunction1(str?: string) { 
  return { 
    pluginId: 'CustomPluginID1', 
    apply(pluginContext) { 
      pluginContext.registerTask({ 
        // 编写自定义任务 
        name: 'customTask1', 
        run: (taskContext) => { 
          console.log('run into: '); 
          const execPromise = util.promisify(exec) 
          execPromise(scriptPath).then(res => { 
            console.log(res, 'res') 
          }).catch(err => { 
            console.log(err, 'err') 
          }) 
        }, 
        // 确认自定义任务插入位置 
        dependencies: ['default@BuildJS'], 
        postDependencies: ['default@CompileArkTS'] 
      }) 
    } 
  } 
} 
 
export default { 
  system: hapTasks, /* Built-in plugin of Hvigor. It cannot be modified. */ 
  plugins: [customPluginFunction1()] /* Custom plugin to extend the functionality of Hvigor. */ 
}
