Via library dependencies

Despite installation via sbt-redacted is the recommended way to add @redacted to your existing project, you can also opt for adding manually the required dependencies.

The procedure is pretty straightforward although, can't stress it enough, using sbt-plugin would be more future-proof, since there are plans to extend the compiler plugin, and using the sbt plugin would make its configuration less error-prone.

If you're still convinced, all you have to do is edit build.sbt like so

build.sbt
lazy val redactedVersion = "x.y.z" // use latest version of the library
// resolvers += DefaultMavenRepository

libraryDependencies ++= Seq(
  "io.github.polentino" %% "redacted" % redactedVersion cross CrossVersion.full,
  compilerPlugin("io.github.polentino" %% "redacted-plugin" % redactedVersion cross CrossVersion.full)
)

Scala.js and Scala Native

redacted is published for the JVM, Scala.js and Scala Native. The annotation library is cross-published, so use %%% to let sbt pick the right platform artifact; the compiler plugin always stays JVM-only (it runs inside the compiler and is never shipped in the final binary), so keep depending on it with %%:

build.sbt
lazy val redactedVersion = "x.y.z" // use latest version of the library

libraryDependencies ++= Seq(
  "io.github.polentino" %%% "redacted" % redactedVersion cross CrossVersion.full,
  compilerPlugin("io.github.polentino" %% "redacted-plugin" % redactedVersion cross CrossVersion.full)
)

Once done that, just import the annotation in your .scala file, and use it like so

src/main/com/your/project/YourClass.scala
package com.your.project

import io.github.polentino.redacted._

final case class YourClass(@redacted email: String, lastLogin: Timestamp)
