CLI parameter submission is not support for this plugin. When invoking jenkins-cli build on a specific job that use "maven metadata plugin":
java -jar jenkins-cli.jar -s http://myjenkins.test.com/ build refresh-setup2-5-install-version -p STATIC_ROLLOUT=1.0.26

I get the following error:
CLI parameter submission is not supported for the class eu.markov.jenkins.plugin.mvnmeta.MavenMetadataParameterDefinition type. Please file a bug report for this

Here is a sample of the config.xml (Changed some namespace for anonymous reason):
<eu.markov.jenkins.plugin.mvnmeta.MavenMetadataParameterDefinition plugin="maven-metadata-plugin@1.0.0">
<name>STATIC_ROLLOUT</name>
<description></description>
<repoBaseUrl>http://nexus.xxxxx.com/content/repositories/xxxxx-repository</repoBaseUrl>
<groupId>com.xxxxx.xxxxx.operating</groupId>
<artifactId>xxxxx-xxxxx-rollout</artifactId>
<packaging></packaging>
<defaultValue></defaultValue>
<versionFilter></versionFilter>
<sortOrder>DESC</sortOrder>
<maxVersions>10</maxVersions>
</eu.markov.jenkins.plugin.mvnmeta.MavenMetadataParameterDefinition>

This feature would be a huge progress for us... Is this plugin still maintained. Thanks for your help/feedback.
