Scalatest testim neden derlenmiyor?

Question

Projemdeki tüm kodu vardır (scala.MatchError): scala.MatchError ile

package fileSearcher 

import org.scalatest.FlatSpec 

class FilterCheckerTests extends org.scalatest.FlatSpec { 
    "Foo" should 
    "not do terrible things" in { 

    assert(1 == 1) 
    } 
} 

sbt testi çöker (aşağıda tam ayrıntılar).

Neyi yanlış yapıyorum? derleyici tarafindan yazdırılır sınıf yolunda, bakarak görebileceğiniz gibi

Answer 1

, sen 2.11 için kütüphaneler ile Scala 2.10 karışık. Scala'nın büyük sürümlerinin ikili uyumsuz olduğu düşünüldüğünde, bu asla işe yaramaz.

Bu scalaVersion := "2.11.5" ile veya otomatik olarak SBT %% vasıta doğru kütüphane sürümünü kullanır libraryDependencies += "group" %% "libName" % "version" ile yapılabilir 2.10 sürümlerini kullanmak için tüm bağımlılıkları ayarlayarak sabitlenebilir. Benzer bir hata alıyorum herkes için

Answer 2

(benim yaptığım gibi) yerine sbt ait Maven'in kullanıldığı Scala 2.10 çalıştıran, çözüm sadece

için

<dependency> 
    <groupId>org.scalatest</groupId> 
    <artifactId>scalatest_2.11</artifactId> 
    <version>3.0.0</version> 
    <scope>test</scope> 
</dependency> 

gelen ScalaTest web sitesinde önerilen Maven'in bağımlılığını değiştirmek olurdu

<dependency> 
    <groupId>org.scalatest</groupId> 
    <artifactId>scalatest_2.10</artifactId> 
    <version>3.0.0</version> 
    <scope>test</scope> 
</dependency>
