Hello, I have done Family Tree Problem but there is some issue with pom.xml file.
I am getting this error in my pom.xml file, " Plugin 'org.apache.maven.plugins:maven-assembly-plugin:' not found" . I am using IntelliJ Idea and I have tried invalidating the cache and also turned on plugin registry but still it is not working. Any suggestions
