Announce: sbt 1.3.8

I’m happy to announce sbt 1.3.8 patch release is available. Full release note is here -

How to upgrade

Normally changing the project/ to


would be ok. However, given that the release may contain fixes to scripts and also because your initial resolution would be faster with *.(zip|tgz|msi) that contains all the JAR files, we recommend you use the installer distribution. They will be available from SDKMAN, Homebrew, scoop, etc.


  • Fixes Coursier resolvers so the project resolvers come first #5413 by @raboof
  • Fixes intermittent NullPointerException in caused by a race condition zinc#731 by @hvesalai
