SLF4J log error in stdout console

[mcinquin]

Hello,

With ROR 1.16.8 and 1.16.9-pre4, i have a SLF4J log error in stdout console for each elasticsearch restart (ES 5.5.0 and Ubuntu 14.04).

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.

How to fix that ?

Thanks.

Thanks for reporting @Shini31, this is fixed missing dependency, will be on the next stable release.
If you notice anything else, let me know!

Thanks for you work and your reactivity!

Hello,

I have the same issue, on version 5.3.0, did you fix this on this version too?

Thanks.

Hello,

The same issue with ROR 1.16.9 and ES 5.5.1

[sscarduzio]

Yes. Unfortunately I had to revert this because it was causing all kind of issues preventing ES to even start. Very sorry :(

I spent half an hour on this, but still couldn't figure it out. Feel free to experiment with adding/removing jars in your ES installation to find a working combination! I'll come back to this in the future (as it doesn't really look as a blocker).

Adding "slf4j-simple-1.7.25.jar" to the zip readonlyrest-plugin and reinstall solve the problem.

@abdox2 can you fix this at gradle level in ROR?

[abdox2]

it's been fixed c08cd63 and revert 0179bbd for some reason. for me it's works just fine with the slf4j-simple.

Readonlyrest 1.16.13
Elasticsearch 5.6.4
Ubuntu 16.04.3

guys, I think I solved this, can you also check? (1.16.15 is out now)

hi, i have the same issue but with ROR 1.18.1_es6.8.0
i added into zip slf4j-simple-1.7.25.jar and reinstall plugin but it doesn't help anyway

UPD: i just downloaded a sources and compilated this one. Then it works fine

I encountered this same error today when running ES v7.8.1 with 1.24.0 of free ROR ES plugin.
