The pom.xml depends on

<dependency>
	<groupId>org.jenkins-ci.plugins</groupId>
	<artifactId>junit</artifactId>
	<version>1.2-beta-3</version>
</dependency>

And the MANIFEST.MF in the cucumber-testresult-plugin.hpi also has a dependency listed for junit 1.2.-beta-3. However, that version of the junit plugin does not exist: http://updates.jenkins-ci.org/download/plugins/junit/

This isn't a big deal and won't really affect anyone installing from the Jenkins UI, but if someone is looking at dependencies, such as those listed in http://updates.jenkins-ci.org/update-center.json, or in the MANIFEST.MF, or the pom.xml, they'll have trouble finding one to satisfy that junit 1.2-beta-3
