No type errors found Version: typescript 3.5.3 Time: 20043ms

the very last 3 lines : No type errors found, but actually eslint-loader reports: 'NetExtra' is already defined (no-redeclare) at src\commons\node\netExtra.ts:26:18:

this situation may mislead developers , especially there are lots of warnings.

if this is because different tools report them, can we have a summary report ?

What is expected?

if any stage of building failed, the final report will report failure

What is actually happening?

the final report says No type errors found when eslint-loader reporting an error

vuejs / vue-cli
