I try to use mvn site
to create site for my maven project, but I get the following Error. I have try to delete maven-site-plugin/
and /org/apache/maven/reporting
from my .m2/repository, but it doesn't work. Is there any know how to solve this problem?

Because org/apache/maven/reporting/AbstractMavenReport
is a class of maven-reporting-impl
, I try to add maven-reporting-impl
as a dependency. However, it still doesn't work.
