webpack plugin error and how to stop build

[hhhpw]

I have a simple webpack plugin. and add this to vue.config.js plugins.
And when i build the vue serve, the plugin works.
In this plugin, i will do some aysnc tasks, and the task maybe fail.
However, the task failed, the serve not stops build process.
I expect if task succeed, the build continue. task failed, stop build process.
so have any comand to stop build process in my codes？
