I am new to maven, and I am exploring it, So for some plugins i would like to have some additional information using theirs "help" goal. However (apart from the basic plugins such as archetype or help : I cite as an example the plugin "maven-jar-plugin"), I get this ERROR in the output ..: ------------- angelo_dev@pluto:~$ mvn maven-jar-plugin:help Downloading: https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-metadata.xml Downloading: https://repo.maven.apache.org/maven2/org/codehaus/mojo/maven-metadata.xml ................

I absolutely don't understand why this can happen... (I use this plugin in my POM.xml and it works) Thank you Angelo
