"Debug Failure. False expression: Output generation failed"

[cjthompson]

If the source files include any type declaration files, like src/@types/my-modules/index.d.ts, the result is:

[15:08:25] Starting scripts
[15:08:25] scripts failed because Debug Failure. False expression: Output generation failed
[15:08:25] Task chain was aborted!

It took a while to figure this out. If I change the code to:

yield fly.source(['src/**/*.ts', '!src/@types/**/*']).typescript().target('dist');

then it will work.

Hi there!

I don't actually use TypeScript, but it seems like you needed to pass in the types option. Can you try this & let me know?

[cjthompson]

Actually, the problem is trying to compile type declaration files. Probably enough to just tweak the example to yield fly.source(['src/**/*.ts', '!src/**/*.d.ts']).

Ah, okay. I assumed that once given a types key, the compiler would have ignored them all internally.
