Hi,

Can cal10n-api be marked as optional dependency (seems it's declared only in slf4j-ext/pom.xml)?

It contains CAL10NAnnotationProcessor which gets called (and can generate a warning because of @SupportedSourceVersion(SourceVersion.RELEASE_5)) when compiling any project that depends on slf4j-ext.

This way we don't need to add exclusions for it transitively.

Best regards,

Andrei Amariei
