问题 I'm new to using SBT, and I'm trying to install and configure Lifty, however when I try to run sbt, I get the following error: [error] (*:update) sbt.ResolveException: unresolved dependency: org.lifty#lifty;1.7.4: not found As per the Installing the Plugin instructions for Lifty, my ~/.sbt/plugins/build.sbt file looks like: resolvers += Resolver.url("sbt-plugin-releases", new URL("http://scalasbt.artifactoryonline.com/scalasbt/sbt-plugin-releases/"))(Resolver.ivyStylePatterns) addSbtPlugin(

问题 I am writing a plugin for SBT that requires a list of the class files generated by the last run of the Scala compiler. This list of class files is then passed into a program that performs some bytecode transformations. Since this transformation process can be slow, I only want the class files written by the last run of the Scala compiler (i.e. those that there modified), not all class files in the output directory. How can I obtain a list of the files last generated by the compile task? 回答1:

问题 How do I make target "package" depend on target "test" ? There is a solution here: Force sbt 0.11 to run tests But it doesn't really work with the xsbt-web-plugin. 回答1: Here's what I did: Keys.`package` <<= (test in Test, Keys.`package` in Compile) map { (_, in) => println("after package & test") in } It runs test, and iff the tests were successful, runs package task. (tested on fresh install of lift-2.5-RC2) 来源： https://stackoverflow.com/questions/15547784/sbt-package-depend-on-test

问题 I am messing around with parsing and scala.tools.nsc.interactive.Global in Scala and I ran into a problem while executing tests under sbt. The tests run fine from Eclipse both with JUnitRunner and the ScalaTest plugin. After long time spent on Google I can't figure out how to fix this. When I execute sbt test the following error is thrown: Exception encountered when attempting to run a suite with class name: compileutils.CompileTest *** ABORTED *** [info] java.lang.ExceptionInInitializerError

问题 I have a project that is build using SBT which packages a single jar using the one-jar plugin. That project contains a bunch of json files in src/main/resources/fixture which I used to access via new java.io.File(App.getClass.getResource("/fixture").getFile Unfortunately this doesn't work any longer since no Resource is returned. I think one-jar uses a special classloading mechanism? Whats the best way to solve this? 回答1: I think one-jar uses a special classloading mechanism? Yes, this must
