the reason shapeless 1.x , shapeless 2.x not compatible. however, if mix dependencies depend on both versions of shapeless sbt's dependency manager default evict older version. that's happened here:
> dependencytree myapp:myapp_2.11:1.0.0 [s] +-com.netaporter:scala-uri_2.11:0.4.7 [s] | +-org.parboiled:parboiled_2.11:2.0.1 [s] | +-com.chuusai:shapeless_2.11:2.0.0 [s] | +-io.spray:spray-routing_2.11:1.3.3 [s] | +-com.chuusai:shapeless_2.11:1.2.4 (evicted by: 2.0.0) | +-io.spray:spray-http_2.11:1.3.3 [s] | | +-io.spray:spray-util_2.11:1.3.3 [s] | | +-org.parboiled:parboiled-scala_2.11:1.1.7 [s] | | +-org.parboiled:parboiled-core:1.1.7 | | ... spray-routing still depends on shapeless 1.x while scala-uri relies on parboiled2 depends on shapeless 2.x.
the solution use spray-routing-shapeless2 module built problems this.
