SBT項目找不到ScalaCheck

Question

使用SBT測試代碼

package examples 
import org.specs2._ 

class ScalaCheckExamplesSpec extends Specification with ScalaCheck { def is = s2""" 
    startsWith ${ prop { (a: String, b: String) => (a+b) must startWith(a) } } 
    endsWith ${ prop { (a: String, b: String) => (a+b) must endWith(b) } } 
    substring ${ prop { (a: String, b: String) => (a+b).substring(a.length) === b } } 
    substring ${ prop { (a: String, b: String, c: String) => (a+b+c).substring(a.length, a.length+b.length) === b } }                              """ 
} 

與SBT配置：

libraryDependencies ++= Seq(
    "org.specs2" %% "specs2-core" % "3.8.5" % "test", 
    "org.scalacheck" %% "scalacheck" % "1.13.4" % "test" 
) 

類ScalaCheck無法找到：

ScalaCheckExamplesSpec.scala:11: not found: type ScalaCheck 
[error] class ScalaCheckExamplesSpec extends Specification with ScalaCheck { 

我該如何解決錯誤？

您需要：

libraryDependencies ++= Seq(
    "org.specs2" %% "specs2-core" % "3.8.5" % "test", 
    // the scalacheck lib will come as a transitive 
    // dependency 
    "org.specs2" %% "specs2-scalacheck" % "3.8.5" % "test" 
)
