parboiled2 and Spray cause conflicting cross-version suffixes
问题 I'm trying to add parboiled2 as a dependency to my project, and follow the Calculator example but it conflicts with spray. My current build.sbt file includes: "io.spray" %% "spray-json" % "1.3.1" withSources() withJavadoc(), "io.spray" %% "spray-can" % sprayV withSources() withJavadoc(), "io.spray" %% "spray-routing" % sprayV withSources() withJavadoc(), "io.spray" %% "spray-testkit" % sprayV % "test" withSources() withJavadoc(), When I add "org.parboiled" %% "parboiled" % "2.0.1" withSources
