If properties to download “Library sources” and “sbt sources” are disabled, then time to dump the structure is reduced from ‘forever’ to less … Read more
sbt: How can I add a local filesystem jar to my project?
You can put the jar in your project’s lib folder (create it if it doesn’t exist), it will then appear on your project’s unmanaged-classpath. To publish a jar file locally, if you have an sbt project that produces the jar, it should be as simple as invoking “publish-local” to publish the jar to your local … Read more
Enforcing Java version for Scala project in sbt?
Using javacOptions ++= Seq(“-source”, “1.7”, “-target”, “1.7”) does not work if you have no Java sources. But you can set the target JVM for the Scala compiler in build.sbt or Build.scala: scalacOptions += “-target:jvm-1.7” As a result it prints on a JDK 6: $ sbt clean run [info] Set current project to default-cd5534 (in build … Read more

How to set main class in build?
The main Class must be fully qualified with the package: Compile/mainClass := Some(“myPackage.aMainClass”) This will work for run and it will set the Main-Class in the Manifest when using the package task. The main class for these tasks can be set separately as in: mainClass in (Compile, run) := Some(“myPackage.aMainClass”) mainClass in (Compile, packageBin) := … Read more
How to prevent java.lang.OutOfMemoryError: PermGen space at Scala compilation?
I use HomeBrew to install sbt on OS X. It supports a SBT_OPTS argument which can be put in ~/.sbtconfig file with export SBT_OPTS=-XX:MaxPermSize=256M.
How to manage multiple interdependent modules with SBT and IntelliJ IDEA?
The approach with multi-project build is the correct one. You can have a nested tree of subprojects of arbitrary length, but you cannot have a module belonging to multiple parent projects. This makes absolutely sense, and in Maven happens the same. The reason is that it would be hard to have the same module into … Read more
