This plugin is currently being developed under name clover-maven-plugin. Since version 4.1.1 it has been renamed to clover-maven-plugin to stay compliant with Apache Maven naming conventions.

The new plugin is backward-compatible and it's enough to change artifactId in the pom.xml and call it by new name, e.g.

<plugin>
    <groupId>com.atlassian.maven.plugins</groupId>
    <artifactId>clover-maven-plugin</artifactId> <!-- maven-clover2-plugin before 4.1.1 -->
    <version>4.1.1</version>
</plugin>

Similarly, when ran from a command line, goals have "clover:" prefix, instead of "clover2:":

mvn clean clover:setup verify clover:clover
 
# before 4.1.1 it was
# mvn clean clover2:setup verify clover2:clover
