Hello,

any ideas why detekt and detektMain give me different violations in one source file for a multimodule project?

Any help would be appreciated.
Thanks

The reason is that some rules require type resolution and and therefore are not enabled when running gradle detekt.

[Stanislav Kral]

And how come that the UnsafeCallOnNullableType is found with detektMain but not with detekt ? How to make it so that both tasks find the violation?

[Stanislav Kral]

Oh, I see this being referenced here: https://detekt.dev/docs/gettingstarted/type-resolution#enabling-on-a-jvm-project

[marschwar]

Yes, there is no way to make it work. You should probably run detektMain and detektTest only.

Sorry, I previously missed this piece of docs. Thanks a lot. It's clear now.
