sbt

问题 I'm trying to build a project with scala 2.11.7 in intellij. I've set the scalaVersion to 2.11.7 , but when I check the external libraries, I can see scala-compiler:2.11.0 . Do I need to declare scala-compiler:2.11.7 as a dependency in build.sbt ? The docs are confusing, seemingly saying that I do need to and then not to in consecutive paragraphs: When using a Scala dependency other than the standard library, add it as a normal managed dependency. For example, to depend on the Scala compiler,

问题 I need to call sbt from ant. I'm doing this with the "exec" task as follows: <target name="publish-jar"> <exec executable="sbt.bat" failonerror="true"> <arg value="publish"/> </exec> </target> I need the ant task to "fail" if the sbt task fails, which is why failonerror="true" is being used. However, this does not work. When the sbt task fails, ant does not report a failed build. This looks like the problem discussed here: Ant exec resultproperty is not working. The suggested workaround is to

问题 I am trying to use ScalaTest (with Scala 2.11.0 and SBT 0.13.x) to generate a single HTML report for a project with many sub projects. To do this, I put the following line in my build.sbt: testOptions in ThisBuild += Tests.Argument(TestFrameworks.ScalaTest, "-h", "target/test-reports") And I have included the pegdown library that is needed for this facility... libraryDependencies in ThisBuild ++= Seq( "org.scalatest" %% "scalatest" % "2.1.7" % "test", "org.pegdown" % "pegdown" % "1.4.2" %

问题 I'm building a scala project(writen in scala 2.11) with SBT 1.x.There are a few "versions of scala" which made me puzzle. SBT 1.x => scala 2.12 SBT plugin => scala 2.x My project => scala 2.11 Please help me to figure out what's the difference or relationship between them.And how SBT tells them apart when compiling or running the project? 回答1: The Scala version used by sbt itself and its plugins is completely independent from the Scala version used to compile the code in your project. The sbt

问题 Every time I launch my app play resolves dependencies. Considering this happens every single launch takes a lot of time... There was a time I had problem with one lib that wasn't unavailable so the app didn't launch... Is there anyway to configure play/SBT to work like Maven? Download dependencies and use local instead resolve every launch? 回答1: Yes, you can do this. Add skip in update := true in to the build.sbt file to stop dependencies resolution. My build.sbt looks like ... scalaVersion :
