Current behavior

The current implementation of createRelativePathMap from gulp-module-resolver is unsafe and does not account for multiple paths specified in tsconfig.

Expected behavior

The plugin should be safe and should resolve multiple paths to be TS complied.

Minimal reproduction of the problem with instructions

Adding an alias with an empty array in tsconfig crashes the gulp-build pipe.
