org.slf4j.LoggerFactory error

[zot...@gmail.com]

We got this error. Looked at the docs and the community site and tried adding all of the following to our build.sbt in various combinations and permutations with no luck:

libraryDependencies ++= Seq(
  "org.slf4j" % "slf4j-simple" % "1.7.21"
)

libraryDependencies ++= Seq(
  "org.slf4j" % "slf4j-log4j12" % "1.7.21"
)

libraryDependencies ++= Seq( "org.slf4j" % "log4j-over-slf4j" % "1.7.21")

Any help would be appreciated.

As it doesn't seem to be specific to ReactiveMongo, but to be a build issue, I suggest you ask on SO, giving error details.

Thanks for the response. However it is specific to reactivemongo, as the error is caused by a call of reactivemongo.

Also, just to clarify, as I noted in my post this issue has been covered in the doco and here as well. My attempts as described above are trying to follow what doco and people here said would solve the problem.

Thanks.

Here's the error message BTW:

You could first have a look at the documentation : http://reactivemongo.org/releases/0.12/documentation/release-details.html#logging

Actually, as noted we did look at the docs which is why we included the logger in our bet as recommended on that page. It still didn't work.

It turned out to be a problem w/the ivy cache. Invalidating & rebuilding the project got us past this problem.
