Importing the library into your build system (e.g gradle, sbt), is not enough. You need to follow an extra step. | Scala 2.11 | Scala 2.12 | Scala 2.13 | | ---------------------------- | ---------------------------- | --------------------------------------------------- | | Import macro paradise plugin | Import macro paradise plugin | Enable compiler flag `-Ymacro-annotations` required | ```scala addCompilerPlugin("org.scalamacros" % "paradise_" % "") ``` Where `` must be the full scala version. For example 2.12.13, and not 2.12. If that doesn't work, google for alternatives. In version scala`2.13.x`, the functionality of macro paradise has been included in the scala compiler directly. However, you must still enable the compiler flag `-Ymacro-annotations`.
