How to run eslint in different folders - vue.js

Question

I came into a eslint problem.
Generally, we have src folder side by side with package.json, like this:
|-projectName
|- src
|- .eslintrc.js
|- package.json
|- vue.config.js
Then i want to take compiling scripts and business code apart into different folders, and to enable them to be linted, i put two '.eslintrc.js' files in each, like this:
|- projectName
|- runtime
|- babel.config.js
|- .eslintrc.js
|- package.json
|- vue.config.js
|- business
|- .eslintrs.js
|- src
|- main.js
|- index.html
|- ...
Then i found eslint turns into chaos:
When i ran 'npm run build', eslint firstly linted files in 'runtime' folder as '.eslintrc.js' in it,
and then vue-cli-service came into building stage, which called eslint again as '.eslintrc.js' in 'template' folder,
but at last the vue-cli-service still finished building even if eslint throws errors, which should stopped building.
The output was like this:
✖ 7 problems (4 errors, 3 warnings)
3 errors and 3 warnings potentially fixable with the `--fix` option.
# ../template/src/store/index.js 14:0-34 18:10-14

I don't know why this happened? Is there someting wrong with eslint config? I just put two '.eslintrc.js' files generated by 'vue craete' command in two different folders , and configure right paths in vue.config.js, like this:
// vue.config.js
...
outputDir: path.resolve(__dirname, '../template/build'),
pages:{
index: {
entry: path.resolve(__dirname, '../template/src/main.js')
}
}
