Question

I use eclipse 4.31 with slf4j.api 2.0.13 and ch.qos.logback.classic 1.5.6. But if i want to log something i get following:

SLF4J(W): No SLF4J providers were found.
SLF4J(W): Defaulting to no-operation (NOP) logger implementation
SLF4J(W): See https://www.slf4j.org/codes.html#noProviders for further details.

I created the eclipse RCP described here:
https://www.vogella.com/tutorials/EclipseRCP/article.html
And the logback logger similar to here (i user later versions):
https://www.vogella.com/tutorials/EclipseLogging/article.html

Here the target platform:

   </configurations>

</product>

According to the manual here the logback-classic.jar on the class path will solve the problem:
https://www.slf4j.org/codes.html#noProviders

I would say the ch.qos.logback.classic is the logback-classic.jar in classpath. But problem still exists.
