`nest build` ignores tsconfig exclude option

Bug Report

Current behavior

nest build ignores tsconfig.json’s exclude option. e.g.: I want to exclude scripts folder from compiling and this works with tsc. But when I run nest build, scripts folder is also compiled and copied to dist.

Input Code

Inside tsconfig.json:

  "exclude": ["node_modules", "dist", "uploads", "static", "scripts"]

Expected behavior

nest build should obey tsconfig excludes.

Possible Solution

Environment

Nest version: 7.0.1
 
For Tooling issues:
- Node version: 13.7.0
- Platform:  Linux 4.4

Others:
Yarn: 1.22.4

Please, provide a minimal repository which reproduces your issue.

From what I’ve reproduced, it works as expected.

// tsconfig.build.json
{
  "extends": "./tsconfig.json",
  "exclude": ["node_modules", "scripts", "test", "dist", "**/*spec.ts"]
}

extends only extends properties in the top level, which means, the exclude array defined in tsconfig.json will be overridden by what is specified in tsconfig.build.json. You need to specify everything defined in tsconfig.json exclude plus the new ones also, in tsconfig.build.json. Hope this helps. @VFC-elindgren
