Classpath error - java.lang.NoSuchMethodError: org.json4s.JsonMethods.render

Hi,

I was trying to use the PgJson4sSupport example from https://github.com/tminglei/slick-pg/blob/master/src/test/scala/com/github/tminglei/slickpg/addon/PgJson4sSupportTest.scala

And I am getting the following error. I believe this has got to do with some classpath issue (with a version mismatch possibly)?

Not sure if it is under your scope, but I think you might find the following links relevant.

http://stackoverflow.com/questions/24877062/receiving-bad-symbolic-reference-to-org-json4s-jsonast-in-eclipse-scala-ide (suggesting you add your dependency “org.json4s” %% “json4s-ast” % “3.2.11”)

Any help would be much appreciated.

Thanks

I thought that you can do it yourself. But, ok, there is another special version for json4s v3.2.11. 😃

pls update your dependency as below to use it:

libraryDependencies += "com.github.tminglei" %% "slick-pg_json4s" % "0.8.5_json4s-3.2.11"

Yes, it should be "com.github.tminglei" %% "slick-pg" % "0.8.5_json4s-3.2.11". It’s still an all-in-one jar for 0.8.x.
