Building a library project using Ant, Ivy, ScalaTest and Scaladoc?
Jumpstart by using this skeleton project.
I was working on a Scala project which needed to be packaged as a library (jar) for used by other Scala/Java projects. My goal was to keep the build file pretty simple without requiring any external dependencies (like having to install scala). I wanted to use:
You can also download the entire skeleton project here and execute ant to build, test and publish the skeleton project jar to local repo.
Lets look at ivy.xml first:
We have three configurations to keep the downloaded dependencies separate. This is usually a good idea, so as to not muddle up your test dependencies with the ones needed only at runtime or at compile time. So, we have:
- core: This is the main library dependencies. If your library needs Commons DBCP, you'd put it in this configuration. If my example, I've listed gson and slf4j as the core dependencies.
- test: This extends core and adds ScalaTest lib on top of the ones in core.
- scala-lang: This fetches scala compiler and library jars.
Here the main targets are:
- docs: builds scaladocs
- build: builds jar
- test: runs tests
- publish: publishes the jar into local repo
