Paths in tsconfig.json not parsed

[tobyryuk]

Our project relies on aliases in the paths key of the tsconfig.json and upon checking, it turns out that paths is being omitted, is there any specific reason for this or can this be added?

tsconfig.json

"paths": {
      "~/*": ["./*"],
      "@/*": ["./*"]
},

Edit:
After looking at the CLI flags, I see that you can't pass paths as a flag, now I'm wondering if there's any reason why the builder is running the CLI with all the flags and not just specifying the config through the tsconfig.json file?
