I am trying to build a Jenkins plugin.
What I already did was creating a Maven project from the hello-world-plugin archetype.
But when I do mvn verify, it gives me the following error:
How can I point it to the hpi package?
Hello @joris and welcome to this community. 
Please, next time you want to show us logs, do a textual copy and paste, not a screenshot. 
I had that kind of error when trying to build a very old plugin with a recent version of Maven.
Could you please show us your pom.xml?
hey gay, i see same error. i using maven3.9.6(use new empty repository) generate new empty plugin.
$ mvn archetype:generate -B -DarchetypeGroupId=io.jenkins.archetypes -DarchetypeArtifactId=empty-plugin -DhostOnJenkinsGitHub=true -DarchetypeVersion=1.22 -DartifactId=somefeature
$ cd somefeature
$ mvn verify

I believe this is cross-posted from
If that’s not the case, then it may be that the same problem is happening here. In that case, the developer was trying to use Java 8 to create a new Jenkins plugin. The Jenkins project stopped supporting Java 8 for development of new plugins over a year ago.
yes, is me. sorry for enfore your double time.
Repeat my results in this:
archetype 1.22 + Java 17 work well.
archetype 1.7 + Java 8 work well.
No continue attempts.
