sbt

I'm happy to announce sbt 1.4.1 patch release is available. Full release note is here - https://github.com/sbt/sbt/releases/tag/v1.4.1

How to upgrade

Download the official sbt launcher from SDKMAN or download from https://www.scala-sbt.org/download.html. This installer includes the sbtn binary.

In addition, the sbt version used for your build is upgraded by putting the following in project/build.properties:

sbt.version=1.4.1

This mechanism allows that sbt 1.4.1 is used only for the builds that you want.

Hi everyone. On behalf of the sbt project, I am happy to announce sbt 1.4.0. This is the fourth feature release of sbt 1.x, a binary compatible release focusing on new features. sbt 1.x is released under Semantic Versioning, and the plugins are expected to work throughout the 1.x series.

The headline features of sbt 1.4.0 are:

• build server protocol (BSP) support
• sbtn: a native thin client for sbt
• build caching
• ThisBuild / versionScheme to take the guessing out of eviction warning

Hi everyone. On behalf of the sbt project, I am happy to announce sbt 1.4.0-RC2. This is the fourth feature release of sbt 1.x, a binary compatible release focusing on new features. sbt 1.x is released under Semantic Versioning, and the plugins are expected to work throughout the 1.x series.

• If no serious issues are found by Saturday, October 3rd 2020, 1.4.0-RC2 will become 1.4.0 final.
• If no serious issues are found by Saturday, September 19th 2020, 1.4.0-RC1 will become 1.4.0 final.

The headline features of sbt 1.4.0 are:

• build server protocol (BSP) support
• sbtn: a native thin client for sbt
• build caching
• ThisBuild / versionScheme to take the guessing out of eviction warning

• sbt-projectmatrix enables parallel building of multiple Scala versions and JVM/JS/Native cross building.
• sbt-projectmatrix 0.6.0 simplifies the generated project ID.
• sbt-projectmatrix 0.6.0 enables Scala 2.13-3.0 interoperability within a build.

I'm happy to announce sbt-buildinfo 0.10.0. sbt-buildinfo is a small sbt plugin to generate BuildInfo object from your build definitions.

Since the last feature release was in 2018, there have been some pending contributions. I think the important thing is that it compiles with -Xlint and -Xfatal-warnings on both Scala 2.13.3 and 2.12.12. Note that sbt-buildinfo 0.10.0 changed to generate scala.collection.immutable.Seq(...) instead of scala.collection.Seq(...).

In this post, we'll try to automate the release of an sbt plugin using Ólafur's olafurpg/sbt-ci-release. The README of sbt-ci-release covers the use case for a library published to Sonatype OSS. Read it thoroughly since this post will skip over the details that do not change for publishing sbt plugins.

Automated release in general is a best practice, but there's one benefit specifically for sbt plugin releases. Using this setup allows multiple people to share the authorization to release an sbt plugin without adding them to Bintray sbt organization. This is useful for plugins maintained at work.

I'm happy to announce sbt 1.3.13 patch release. Full release note is here - https://github.com/sbt/sbt/releases/tag/v1.3.13.

Special thanks to Scala Center. It takes time to review bug reports, pull requests, make sure contributions land to the right places, and Scala Center sponsored me to do maintainer tasks for sbt during June.

I'm happy to announce sbt 1.3.12 patch release. Full release note is here - https://github.com/sbt/sbt/releases/tag/v1.3.12.

Special thanks to Scala Center. It takes time to review bug reports, pull requests, make sure contributions land to the right places, and Scala Center sponsored me to do maintainer tasks for sbt during May. Darja + whole Scala Center crew have been chill to work with.

Change since sbt 1.3.11

There was a regression in sbt 1.3.11 around the launcher integration, which showed up as repositories file getting ignored. sbt 1.3.12 fixes it. #5583

Update: There was a regression in sbt 1.3.11. Please use 1.3.12 instead.

Selective functor can facilitate conditional execution of tasks while keeping the ability to run inspect command.

Selective composition can be implemented in sbt as Def.taskIf macro:

Def.taskIf {
  if (Boolean) something1
  else something2
}
