This spring, Eugene ( revisited this again to make a few more changes so we can swap out the LM engine in #4614 with the help from Alex. During the fall, it was further improved by Andrea Peruffo ( and lm-coursier eventually became part of coursier/sbt-coursier repository maintained by Alex. Early in 2018 Leonard Ehrenfried ( started the Coursier-backed LM API implementation as lm#190. Many people were involved in the effort of bringing Coursier to sbt. If you wish to go back to Apache Ivy for library management, put the following in your build.sbt: Note: Under some situations, Coursier may not resolve the same way as Ivy (for example remote -SNAPSHOTs are cached for 24 hours). Coursier is a dependency resolver like Ivy, rewritten in Scala by Alexandre Archambault ( aiming to be a faster alternative. Sbt 1.3.0 adopts Coursier for the library management. To disable this behavior, either set Compile / run / fork := true or run sbt with =false. This may cause downstream crashes if the task uses ShutdownHooks or if any threads created by the tasks continue running after the task completes. ClassLoader management: To prevent resource leaks, sbt 1.3.0 closes the ephemeral ClassLoaders used by the run and test tasks after those tasks complete.

Please use CrossVersion.disabled instead sbt/librarymanagement#316 #4456 by Deprecates HTTP resolvers, but allow localhost or resolvers marked. Multi command no longer requires leading semicolon.Combined together we hope these features will improve the user experience of running your builds. The headline features of sbt 1.3 are out-of-box Coursier library management, ClassLoader layering, IO improvements, and super shell. sbt 1.x is released under Semantic Versioning, and the plugins are expected to work throughout the 1.x series. This is the third feature release of sbt 1.x, a binary compatible release focusing on new features.
