@RyanCavanaugh Please help. The project was folked from your demo and the layout was changed to reflect our need. Thanks in advance.

@RyanCavanaugh Any update?

I did more experiment and this project layout works - https://github.com/raymondfeng/learn-a/tree/ts.

Please note that I use ts as the rootDir to contain src and test so that dist is NOT under rootDir. But the project layout is not so intuitive.

I guess the issue is related to the fact that outDir ("dist") is under the rootDir (".") and include/exclude in tsconfig.json is not being honored in this case.

@raymondfeng see discussion in #26867
Your issue is probably caused by outDir being located inside rootDir

[raymondfeng]

@ajafff It seems so but my project layout should be legitimate as it works well with normal (without -b) tsc compilation.

Interesting. Maybe we can try to split each package into two sub-projects, one for src and another for test, as described in http://www.typescriptlang.org/docs/handbook/project-references.html#an-example-project?

@raymondfeng Is this still issue? I cloned your repo and built it and it works.
Note in your repo, the include was inside compilerOptions which I moved out and it seems to work and build without any errors after that.

If this is still an issue, please provide more information

@sheetalkamat I fixed the tsconfig and upgraded to TypeScript 3.1.1. Everything seems to be work fine now! Thanks a lot. I'll try with a much larger project at https://github.com/strongloop/loopback-next
