我按照文档新建了MyAbilityStage，并且在该模块对应的 module.json5中配置如下，但是在预览启动时，log控制台没打印，求解惑
代码如下

import AbilityStage from '@ohos.app.ability.AbilityStage';


export default class MyAbilityStage extends AbilityStage{
  onCreate(): void {
    console.log("MyAbilityStage onCreate")
  }

}

  "module": {
    "name": "entry",
    "type": "entry",
    "description": "$string:module_desc",
    "mainElement": "MyAbilityStage",
    "srcEntry": "./ets/myabilitystage/MyAbilityStage.ets",
    "deviceTypes": [
      "phone"
    ],

        "exported": true,
        "skills": [
          {
            "entities": [
              "entity.system.home"
            ],
            "actions": [
              "action.system.home"
            ]
          }
