Errors deploying with version 2.3

[valcamonica]

Using version 2.3 as build extension, i.e.:

<extension>
    <groupId>com.gkatzioura.maven.cloud</groupId>
    <artifactId>google-storage-wagon</artifactId>
    <version>2.3</version>
</extension>

generates an error, following a call to mvn -e deploy:

org.apache.maven.lifecycle.LifecycleExecutionException: Internal error in the plugin manager getting plugin 'org.apache.maven.plugins:maven-resources-plugin': Plugin 'org.apache.maven.plugins:maven-resources-plugin:2.3' has an invalid descriptor:

Note: deleting folder ~/.m2/repository/com/gkatzioura/ does not fix the issue.
