Why does json4s need a Scala compiler as a runtime dependency -


i've discovered using json4s native

    <dependency>         <groupid>org.json4s</groupid>         <artifactid>json4s-native_2.10</artifactid>         <version>3.2.9</version>     </dependency>

brings scalap , scala-compiler dependencies.

why need it?

does generate code on fly @ runtime?

why doesn't use macros processing @ compile time?

the people of json4s have answered me in this issue following:

because need read byte code find out information scala primitives. more necessary on 2.9 on 2.10
