To use shouldmatchers with maven you need to add repository to your pom or settings file

<repository>
    <name>piotrga</piotrga>
    <url>http://piotrga.github.com/maven-repo</url>
</repository>

You also need to add the dependency:

<dependency>
    <groupId>closures</groupId>
    <artifactId>closures</artifactId>
    <version>1.0.10</version> // please set the version to the one you want to use
</dependency>

Jar can be downloaded from:
http://piotrga.github.com/maven-repo/closures/closures/{version}/closures-{version}.jar

ie.
http://piotrga.github.com/maven-repo/closures/closures/1.0.10/closures-1.0.10.jar
