Do not require silencer-lib on classpath

Firstly, just wanted to say thanks for this plugin! I found it through this bug report in Play.

When using the plugin as described there, I don’t need the @silent annotation, since I’m only excluding files based on paths rather than with the annotations - so it’s a bit annoying (and ironic 😛) that the plugin generates the following warning:

[warn] `silencer-plugin` was enabled but the @silent annotation was not found on classpath - have you added `silencer-lib` as a library dependency?

Would it be sensible to remove this warning?

perhaps some of your subprojects lack these options

Ahh of course! This is my mistake: I had the compiler plugin enabled on all my subprojects (which all share the same basic configuration) but of course only enabled the filters on some subprojects (e.g. Play modules). You’re quite right - it absolutely makes sense to still emit the warning in the “vanilla” case.

Thanks (again) for being so responsive 😃

I’ve tested this on a minimal project and it seems to work as intended. Without any options the warning is emitted but when I enable either messageFilters or pathFilters, the warning disappears. Perhaps some of your subprojects lack these options or have the plugin unnecessarily enabled in the first place (maybe the root project in sbt?).

This warning was originally introduced to avoid build mistakes like this one. If it turns out to be more annoying than helpful then maybe I should remove it again…
