copied!<p>The question is in danger of just generating lots of opinions; it would be better to have a clear list of requirements or a description of your environment, previous knowledge, etc.</p> <p>FWIW, there are more opinions in <a href="http://www.scala-lang.org/node/11935" rel="noreferrer">this scala mailing list thread</a>.</p> <p>My 2c are: Go with sbt if you don't have specific requirements</p> <ul> <li>for simple projects, it's totally effortless (you don't even need a build file until you have dependencies)</li> <li>it is commonly used across Scala open source projects. You can easily learn about configuration by peeking into other people's projects. Plus many projects assume you use sbt and provide you with <a href="https://github.com/milessabin/shapeless#using-shapeless" rel="noreferrer">ready-made copy+paste instruction</a> for adding them as a dependency to your project.</li> <li>if you use IntelliJ IDEA, it can be totally integrated. You can <a href="https://github.com/orfjackal/idea-sbt-plugin/wiki" rel="noreferrer">have IDEA use sbt</a> to continuously compile your project, and vice versa you can use sbt to quickly <a href="https://github.com/mpeltonen/sbt-idea" rel="noreferrer">generate IDEA projects</a>. The last is extremely useful if you are in a 'snapshot' cycle with depending on other of your own libraries which are bumped from minor version to minor version -- just close the project, update the version in the build file, re-run the <code>gen-idea</code> task, and re-open the project: updates done.</li> <li>comes ready with most tasks you will need (<code>compile</code>, <code>test</code>, <code>run</code>, <code>doc</code>, <code>publish-local</code>, <code>console</code>) -- the <code>console</code> is one of the best features.</li> <li>some people highlight the feature that dependencies can be source repositories directly grabbed from GitHub. I haven't used this so can't comment here.</li> </ul> <p>Some people hate sbt because it uses Ivy for dependency management (I can't comment on its pros and cons, but most of the time it is a non-issue), some people hate sbt because you specify the build file in terms of a Scala DSL instead of XML. Some people were disappointed that sbt's format changed from v0.7 to v0.10, but obviously, migration won't affect you if you start from scratch.</p>
