Resolve pom.xml errors

[Manar El Kefi]

I am creating a first plugin with jira data center. The problem is that pom.xml contains errors that I have not been able to resolve. Here are the errors:

* Project build error: Unresolveable build extension: Plugin com.atlassian.maven.plugins:jira-maven-plugin:8.1.2 or one of its dependencies could not be resolved: The following artifacts could not be resolved: com .atlassian.maven.plugins:jira-maven-plugin:jar:8.1.2 (present, but unavailable): com.atlassian.maven.plugins:jira-maven-plugin:jar:8.1.2 was not found in https: //repo.maven.apache.org/maven2 during a previous attempt.

* Project build error: Unknown packaging: atlassian-plugin

here is pom.xml :

Hi @Manar El Kefi 

It is better to ask you question on the developer community, this should give you more traction than the global community.
