NoSuchMethodError running release candidate

[aninhumer]

Using versions:

• sbt version 0.13.16
• neo-sbt-scalafmt version 1.15 (coursier version sbt-scalafmt-coursier)
• scalafmt version 1.6.0-RC1 (set in scalafmtVersion sbt setting)

When I run scalafmt like this:

sbt scalafmt

Scalafmt fails with the following error message:

[error] (compile:scalafmt::scalafmtter) com.google.common.util.concurrent.ExecutionError: java.lang.NoSuchMethodError: org.scalafmt.config.Config$.fromHoconString(Ljava/lang/String;Lscala/Option;)Lmetaconfig/Configured;

Using scalafmt version 1.5.1 this does not occur.

Thanks for reporting! I admit I removed this method too eagerly, it was previously not well documented that only org.scalafmt.Scalafmtis protected by binary compatibility. Docs on integrating with scalafmt as a standalone library are here https://scalameta.org/scalafmt/#Standalonelibrary

Given this is the second ticket on the same issue (see #1204) I think it's best to re-introduce the old method

Opened #1212 to fix this issue

Note that neo-scalafmt is using internal APIs which are subject to binary and source breaking changes between any release. Docs on using scalafmt as a library can be seen here https://scalameta.org/scalafmt/#Standalonelibrary
