sbt-buildinfo v0.9.0 Release Notes

Release Date: 2018-04-16 // over 2 years ago
  • 🏗 sbt-buildinfo 0.9.0 is published for sbt 1.

    🏗 TaskKey to BuildInfoKey conversion potentially breaking semantic change

    TL;DR No need for BuildInfoKey.of(...) or BuildInfoKey.ofN(...) any more. Use BuildInfoKey.outOfGraphUnsafe if your build definition is now circular.

    🏗 sbt-buildinfo 0.8.0 deprecated the original TaskKey[A] to BuildInfoKey.Entry[A] implicit and explicit conversions (BuildInfoKey.task and BuildInfoKey.apply respectively), that executed the underlying sbt Task out of sbt's task graph execution, in favour of a newly introduced BuildInfoKey.of(...) and BuildInfoKey.ofN(...) API, which correctly wired up the task graph. See #114.

    🚀 As it was implemented (and released) it interacted poorly with sbt-buildinfo's API (#117), due to a mistake in the implementation and test coverage.

    🏗 In resolving the issue it became clear that instead of introducing a new API, that required sbt-buildinfo users to change their source code to use, the already used conversions could have been modified to use the new Task-based semantics.

    🏗 However, this change breaks any build definition that declares as a build info key any TaskKey that depends on sourceGenerators or resourceGenerators, because the build definiton would now be circular and fail to load. To fix this breaking semantic change the user has to either drop the key used, choose another key, or fallback to the previous semantics by using the not-deprecated BuildInfoKey.outOfGraphUnsafe API, also introduced in sbt-buildinfo 0.8.0.

    ➕ Add direct support for sbt's Attributed

    🏗 A number of keys defined by sbt use sbt's Attributed type, specifically the keys that define classpaths. Prior to this change defining any of these keys as a build info key would generate Seq[String] as Attributed would be simply converted to string with toString. sbt-buildinfo 0.9.0 introduces direct support for these keys so they generate Seq[File] instead.

    👉 Make toJson more JSONish

    🏗 sbt-buildinfo is able to generate toJson method using the following setting:

    buildInfoOptions += BuildInfoOption.ToJson

    🏗 sbt-buildinfo 0.9.0 makes the JSON encoding more natural:

    "libraryDependencies" :
      [ "org.scala-lang:scala-library:2.12.4",

    Do not generate multi-parameter infix calls

    🚚 Multi-parameter infix calls may be removed in the future, so it's better not to generate this kind of code.

Previous changes from v0.8.0

  • 🏗 sbt-buildinfo 0.8.0 is published for sbt 1.

    🏗 BuildInfoKey.of(...) and BuildInfoKey.ofN(...)

    🏗 Prior to 0.8.0 when sbt-buildinfo generated the BuildInfo object using tasks, it was executing the tasks out-of-graph.
    This would occasionally cause race conditions when used with side-effecty tasks.

    🏗 To workaround this issue sbt-buildinfo introduces a new BuildInfokey.of(...) and BuildInfoKey.ofN(...) macro that will safely execute the tasks within the control of the task engine.

    Before 0.8.0

    lazy val root = (project in file(".")) .enablePlugins(BuildInfoPlugin) .settings( buildInfoKeys := Seq[BuildInfoKey](name, version, someTask), buildInfoPackage := "hello" )

    After 0.8.0

    lazy val root = (project in file(".")) .enablePlugins(BuildInfoPlugin) .settings( buildInfoKeys := BuildInfoKey.ofN(name, version, someTask), buildInfoPackage := "hello" )
