Error: value seq is not a member of object slick.dbio.DBIO

I am writing a web application in play framework. I decided to use slick (FRM) to query in my database (postgre). I am new to slick so I started following slick official document for revision 3.0.0 http://slick.typesafe.com/doc/3.0.0/gettingstarted.html

As per the documentation, I added dependencies in my build.sbt file

libraryDependencies ++= Seq(
  "com.typesafe.slick" %% "slick" % "3.0.0",
  "org.slf4j" % "slf4j-nop" % "1.6.4"
)

Everything else is working fine but while writing below line in my Scala IDE. It is showing error that

value seq is not a member of object slick.dbio.DBIO

val setup = DBIO.seq(
// Above line is showing error

(suppliers.schema ++ coffees.schema).create,
.
.
.
)

In fact Scala IDE (same as eclipse IDE) isn't detecting any member of object DBIO though when I browse slick api of same version http://slick.typesafe.com/doc/3.0.0/api/#slick.dbio.DBIO$ for object DBIO I am seeing seq as it's member.

Where am I doing wrong?

I opened a bug with scala ide: assembla.com/spaces/scala-ide/support/tickets/1002527 – Chris Scott
I tracked the problem to a known bug in the presentation compiler and REPL, and submitted a workaround for the next release of Slick: stackoverflow.com/questions/30436661/… – retronym
@retronym can you fix your link? You're just linking back here with your work-around. – Chris Scott
Looks like it's this pull-request: github.com/slick/slick/pull/1224 This will probably hit slick in 3.1. – Chris Scott

As anticipated by retronym and Chris Scot, this problem was fixed with the release of Slick 3.1

You need to import the API for the database you are using:

import slick.driver.PostgresDriver.api._

I'm not sure if you've got your answer (I'm answering for those that may stumble upon this in the future), but I've resolved this by upgrading to 3.0.0-M1 and using Action.seq() instead of DBIO.seq()

This may also work in 3.0.0, but I'm not sure as I upgraded from Slick 2.x to 3.0.0-M1!
