This line https://github.com/playframework/play-slick/blob/master/samples/basic/build.sbt#L3 seems to give error when running sample play app. Here's how you can reproduce the error:

$ cd basic
$ sbt run
[info] Updated file /tmp/play-slick/samples/basic/project/build.properties: set sbt.version to 1.0.4
/tmp/play-slick/samples/basic/build.sbt:3: error: not found: value PlayKeys
PlayKeys.playOmnidoc := false
