[SOLVED] Build Failure in Stromcrawler 1.16

i am using stormcrawler 1.16, apache storm 1.2.3, maven 3.6.3 and jdk 1.8.

i have created the project using the articfact command below-

mvn archetype:generate -DarchetypeGroupId=com.digitalpebble.stormcrawler -Darche typeArtifactId=storm-crawler-elasticsearch-archetype -DarchetypeVersion=LATEST

when i run mvn clean package command then i get this error -

   /crawler$ mvn clean package

i put com.cnf.245 in groupId and crawler in articfactId.

someone please explain what cause this error ?
