ProtoQuill on Ammonite

commands.scala

// This will download ammonite and put into /usr/local/bin. Command is `amm3`, if you already have `amm` it won't be affected
// sudo sh -c '(echo "#!/usr/bin/env sh" && curl -L https://github.com/com-lihaoyi/Ammonite/releases/download/2.5.2/3.1-2.5.2) > /usr/local/bin/amm3 && chmod +x /usr/local/bin/amm3' && amm3

import $ivy.`io.getquill::quill-sql:3.16.3.Beta2.3`
// https://repo1.maven.org/maven2/io/getquill/quill-sql_3/3.16.3.Beta2.3/quill-sql_3-3.16.3.Beta2.3.pom...
// import $ivy.$

import io.getquill._
// import io.getquill._

val ctx = new SqlMirrorContext(PostgresDialect, Literal)
// ctx: SqlMirrorContext...

import ctx._
// import ctx._

case class Person(name: String, age: Int)
// defined class Person

run(query[Person]).string
// res13: String = "SELECT x.firstName, x.lastName, x.age, x.blah FROM Person x"

That's odd, 3.16.3.Beta2.3 should be working fine with java 17. What was the error?
Also did you need to import something besides io.getquill._ ?
