No SLF4J providers were found warning with fscrawler 2.10

Question

I have upgraded fscrawler from 2.9 to 2.10. I tried the same command towards indexing that I used in the older version:

/usr/bin/fscrawler --config_dir /home/user1/conf test_index --restart --loop 1

I see the following warning about SLF4J:

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See https://www.slf4j.org/codes.html#noProviders for further details.
SLF4J: Class path contains SLF4J bindings targeting slf4j-api versions 1.7.x or earlier.
SLF4J: Ignoring binding found at [jar:file:/usr/local/src/fscrawler-distribution-2.10-SNAPSHOT/lib/log4j-slf4j-impl-2.20.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See https://www.slf4j.org/codes.html#ignoredBindings for an explanation.

I am using Log4j for logging purposes instead of using any Java logging library. How to get rid of the above warning related to SLF4J?

Did you download the latest build or an old one?

Make sure you download the latest build. That should be fixed.

I have downloaded version: fscrawler-distribution-2.10-20230501.083424-195.zip – Manoj Agarwal May 04 '23 at 09:25
Does latest build mean v2.9, the released version or the latest available version 2.10-x? – Manoj Agarwal May 04 '23 at 11:55
Weird as this one is normally good to use. I need to check it manually. Could you open an issue in the project with the downloaded version as you wrote above? – dadoonet May 05 '23 at 14:10
