Is there a Java continuous testing plugin for Maven?

Question

I'm looking for a plugin that would run in a console continuously to scan a Maven project's test sources directory, and when it detects a change kicks off a test cycle. Something analogous to mvn scala:cc or the Scala Build Tool, but for Java. Can anyone point me towards one?

This might be obvious but, you are aware that there are continuous integration servers with good support for maven, right? e.g. [Jenkins-CI](http://jenkins-ci.org/) — Miquel, Jul 05 '12 at 15:56
Yeah, I do. I am looking for something simple out of the box to run in a console alongside a text editor when I don't have access to a full-blown IDE. — Jakub Korab, Jul 05 '12 at 16:00
Ok, all clear. You want eclipse's autobuild functionality minus eclipse :) — Miquel, Jul 05 '12 at 16:01
but jenkins offer a consloe command interface to manipulate it — Moataz Elmasry, Jul 09 '12 at 11:02

I have personally used sbt even for a java only project just for continuous test feature.

I added a sbt build file to a maven based project and use sbt when developing, but use maven when building the final package, starting embedded jetty etc and this has worked out quite well.

That's certainly one way to do it, but I'm looking for something that wouldn't require me to introduce sbt. – Jakub Korab Jul 06 '12 at 09:24
It's quite possible that there isn't actually a Maven continuous compilation plugin, so this is the best answer that I received. Thanks! – Jakub Korab Jul 17 '12 at 08:47

I've just discovered that the scala-maven-plugin supports both continuous compilation & testing, as well as cross-compilation (Java + Scala). So it's possible to use it over a pure Java build and get all the continuous build goodness.

Recently, I have had a need for a solution to this. Having been learning scala and finding about the goodness of sbt ~test, I want to apply it to Java projects that do not have continuous test.

Using the scala-maven-plugin that you mentioned, I have created a github seed that will run Java Junit tests everytime I save a Java source or a Java test.

Check it out: https://github.com/ailveen/maven-scala-java-continuous-test

The project is very simple right now (contains only Java files because that is my current need) but in the future I hope to add scala test (or specs2 or scalacheck) so it works with mixed java and scala files.

Hope you find it useful.

It is not exactly for Maven, but JUnit Max does continuous testing and if you're on Eclipse it might be the tool you would like to check out
