Description

In the v3 version of UIMA Ruta logger errors are logged in the console when running a Ruta script:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
SLF4J: Failed to load class "org.slf4j.impl.StaticMDCBinder".
SLF4J: Defaulting to no-operation MDCAdapter implementation.
SLF4J: See http://www.slf4j.org/codes.html#no_static_mdc_binder for further details.

Reproduce

• Install UIMA Ruta 3.0.1 into a fresh eclipse
• Import the example projects
• Enable the console view
• Run ExampleProject/script/uima/ruta/example/Main.ruta

I think this is quite a problem because it looks like no logging information will be provided neither from Ruta nor from any potential delegate UIMA v3 components which all use SLF4J by default now.
