所以我一直在嘗試使用parboiled2過去的幾個星期，它可能是最困難的依賴添加到構建我在我的整個生活中遇到過。我現在的錯誤是編譯sbt assembly）錯誤：Parboiled2導致「加載類文件'Prepender.class'時檢測到缺失或無效的依賴關係」
[error] missing or invalid dependency detected while loading class file 'Prepender.class'.
[error] Could not access type PrependAux in package shapeless,
[error] because it (or its dependencies) are missing. Check your build definition for
[error] missing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)
[error] A full rebuild may help if 'Prepender.class' was compiled against an incompatible version of shapeless.
[error] .../Main.scala:56: could not find implicit value for parameter prepender: spray.routing.Prepender[shapeless.HNil,shapeless.::[String,shapeless.HNil]]

[error] ^
看來，這是根本不可能進行噴霧和Parboiled2發揮好起來。
我試過sbt clean並刪除我的target目錄。我的build文件基本上是這樣的：
resolvers ++= Seq(
"spray repo" at "http://repo.spray.io"
)
val akkaV = "2.3.6"
val sprayV = "1.3.2"
libraryDependencies ++= Seq(
// If I comment this line, everything works fine.
"org.parboiled" %% "parboiled" % "2.0.1" withSources() withJavadoc(),
//
"org.scalacheck" %% "scalacheck" % "1.12.1" % "test" withSources() withJavadoc(),
"org.specs2" %% "specs2-core" % "2.4.15" % "test" withSources() withJavadoc(),

)
scalaVersion := "2.11.4"
javaOptions ++= Seq("-target", "1.8", "-source", "1.8")
我sbtVersion是0.13.6，我sbt-assembly版本是0.12.0
升級到2.11，提升我specs2依賴關係之前，我得到：parboiled2 and Spray cause conflicting cross-version suffixes
