Çalıştığım almaya çalışıyorum this multi-module build configuration var, ama aşağıdaki hata ile başarısız proje derlemeye çalıştığınızda zaman:başarısız "MissingRequirementError: derleyici aynada nesne scala.runtime bulunamadı."?

bu nedir ve bunu nasıl düzeltebilirim fikrin var mı?

bir proje bağımlılık olarak scala-library ekleme:

"org.scala-lang" % "scala-library" % "2.10.1"

trick yaptı. Hala bunun neden gerekli olduğundan emin değil ama daha önce olmadı. Bir yapı tanımında libraryDependencies için bağımlılıkları eklemek için := değil ++= veya += kullanarak, yani senin ayarlarken açık tüm proje yukarı bağımlılıkları zaman

Ben aynı sorunu vardı ve Projemde * Bütün * ekstra dosyaları kaldırarak düzelttim:

sonuç aşağıdaki gibi olacak. Sadece tüm 'hedef /' dirs, ancak tüm 'proje/hedef /' dirs de (Ben ikinci onu çözdüm biri olduğunu düşünüyorum ve onlar sbt clean' 'tarafından kaldırılıyor değildi). – Dan

Doğru çözüm olduğunu düşünmüyorum. * Scala * lib, * scalaVersion * ile belirtilen sürümle otomatik olarak çekilmelidir. Temizliği denemelisiniz, sonra her şeyi yeniden inşa etmelisiniz. – davidshen84

konudur, build.sbt söz: Bütün := ile

libraryDependencies := Dependencies.microservice

libraryDependencies yılında ayarlıyoruz setleri SBT cari bağımlılıkları dışarı temizlenir ve sadece kullanılabilir bağımlılıkları (yukarıdaki örnekte olduğu gibi) Dependencies.microservice gelen bunlar.

"org.scala-lang" % "scala-library" % "2.10.1" Ekleme (veya kullandığınız scalaVersion sürümü), zaten düzgün bir şekilde başlatılmış olan libraryDependencies ayarının temizlenmesi için bir geçici çözümdür.

Bu şu inşa tanımıyla çoğaltmak kolay bulunuyor - build.sbt: yanlışlıkla Scala dosyaların sonuçları derlemek çalışılıyor

libraryDependencies := Seq()

- show libraryDependencies not: aşağıdaki
