When I read the documentation carefully, I found that there was a problem with my code, which has been solved now. The main reference is here http://www.ydcss.com/archives...
The main problem is the dependency of each task. It is very likely that the json file of the manifest cannot be found when the task is executed. Now add it After the dependency, replace ok. One thing that needs to be reminded is that because the call is dependent, it is best to take the return value of return. This way it is easier to use
