How do I find outdated libraries with sbt? - sbt

Question

How can I find libraries which have newer versions with sbt.
For Ruby bundler, it can be done with bundle outdated. I want to do similar thing with sbt.

Answer 1

There is sbt-updates which gives you latest stable and snapshot versions. Not sure how reliable it is, though.
Example run:
my-project $ sbt
[info] Set current project to my-project
> dependencyUpdates
[info] Found 14 dependency updates for my-project
[info] com.typesafe.akka:akka-actor : 2.2.1 -> 2.2.3
[info] com.typesafe.akka:akka-agent : 2.2.1 -> 2.2.3
[info] com.typesafe.akka:akka-dataflow : 2.2.1 -> 2.2.3
[info] com.typesafe.akka:akka-slf4j : 2.2.1 -> 2.2.3
[info] com.typesafe.akka:akka-testkit : 2.2.1 -> 2.2.3
[info] com.typesafe.akka:akka-zeromq : 2.2.1 -> 2.2.3
[info] org.scala-lang.plugins:continuations:plugin->default(compile) : 2.10.2 -> 2.10.3
[info] org.scala-lang:scala-library : 2.10.2 -> 2.10.3
[info] org.scalaz:scalaz-concurrent : 7.0.3 -> 7.0.5
[info] org.scalaz:scalaz-core : 7.0.3 -> 7.0.4
[info] org.scalaz:scalaz-effect : 7.0.3 -> 7.0.5
[info] org.scalaz:scalaz-iteratee : 7.0.3 -> 7.0.5
[info] org.scalaz:scalaz-typelevel : 7.0.3 -> 7.0.5
[info] org.scalaz:scalaz-xml : 7.0.3 -> 7.0.5

You can use "SBT > dependencyUpdates" in the command line. Just like described above. That will work. But that is now automated.
You can use VersionEye to monitor your build.sbt file on GitHub/Bitbucket. VersionEye will notify you about out-dated dependencies in your project, automatically via email. In that way it is completely automated and you don't have to remember to execute commands in the shell. It's like a CI Server for versions ;-)
By the way, I'm the dude who started VersionEye. Let me know if you have questions.
