Question

I get the following error using the mvn -X validate command:
The POM for org.apache.maven.plugins:maven-jar-plugin:jar:2.3.1 is invalid, transitive dependencies (if any) will not be available: 3 problems were encountered while building the effective model for org.apache.maven.plugins:maven-jar-plugin:2.3.1
